Test of the best: 3-season down sleeping bags reviewed

PACKED SIZE AND WEIGHT
A small packed size and low weight is essential when backpacking, so you can easily store the bag into a rucksack. Sizes stated are the minimum achieved when the bag is stuffed into its stuffsack and this is compressed as small as possible. Weights stated include the stuffsack.

CONSTRUCTION
Most of the bags here use a box wall construction, where the down is trapped inside box-shaped baffles within the bag, rather like bricks in a wall. To reduce cold spots, some bags use trapezoid and slanted wall-shaped boxes. 

SHELL AND LINING
To protect the insulation, the shell and lining benefit from some water-resistance, and in some cases this may be enhanced on the base, foot and hood areas. Nylon is often used for the shell and lining, but polyester could be used to reduce prices.

INSULATION
The bags featured here all use down insulation. Down has the advantage over synthetic insulation of being more efficient at trapping air, and therefore it can be used to produce lighter and less bulky sleeping bags. It doesn’t maintain its performance when damp very well though, so some manufacturers treat the down (or shell) to help it resist water and dry quicker when damp.

SIZE
If a bag is too big you’ll have more air inside to heat up, and this will tend to move around and escape from the bag. If the bag is too small you’ll be uncomfortable, as you’ll be restricted in movement and the insulation will become compressed so it won’t trap air to keep you warm. Some bags are available in a choice of lengths and there are also women’s models. It is always worth checking with the manufacturer if you need a slightly different size, as there may be size differences available. Sizes stated are for the standard bags.

ZIP
Zip designs vary from half-length to full-length side zips – the former offering a weight saving, the latter making a more versatile bag for hot nights. Zips may come with an anti-snag strip behind them to prevent jamming, or a wide insulation-filled baffle to prevent cold spots along the length of the zip. 

HOOD
The fit and degree of insulation in the hood is important in cold conditions. A drawcord will be provided to cinch it in, but some hoods are easier to adjust, making their fit and comfort level better than others.

SHOULDER BAFFLE
A good shoulder baffle keeps the air down in the bag, which increases its insulating ability. The best can be adjusted to fit closely, while lighter or lower-priced bags may have non-adjustable shoulder baffles, or no shoulder baffle at all.


Alpkit PipeDream 400 £215

Alpkit.jpg
  • Lowest comfort temperature rating -6°C
  • Packed size 18x22cm
  • Weight 877g (including 29g stuffsack)

IT'S GOOD What is not to like here? The price is great compared to other down bags, and the weight and packed size are very impressive and more than acceptable for backpacking. The insulation is 750 fill power down and it has even been treated with a Nikwax process so it maintains better performance if it gets slightly damp. The down is held in a box wall construction, and the shell is made from polyester rather than more pricey nylon to help keep costs down. You get a full-length side zip and there is a drawcord around the hood. All of this is great for anyone on a budget wanting a great backpacking bag.

HOWEVER The drawbacks are that you are not getting a full shoulder baffle, although it does at least have a front chest baffle that is well padded – so this is only a small negative point. Also the size is slightly smaller than some other bags at 78cm width and 215cm length, so again this depends on your body size. The hood fit is not quite as neat as the best here and the drawcords are not as well baffled for comfort against the head either. If you pay more you get nylon shell materials and even higher performance down for an even lighter bag. So this may not be absolute best performance available, but at this price, does that matter?

VERDICT Outstanding value when you compare it to other options, but if you do pay more, you’ll get more benefits.

Exped Versa 600 £240

Exped.jpg
  • Lowest comfort temperature rating -5°C
  • Packed size 20x23cm
  • Weight 1181g (including 63g stuffsack)

IT'S GOOD What sets this bag apart from every other bag here is its spaciousness. This bag is massive and benefits from a square rather than heavily-tapered footbox area, so you have plenty of room. Also the shoulder width is 89cm and the length is 225cm. The side zip extends around the base of the foot, so you can open this up fully on hot nights. Importantly you also get a good temperature rating and the hood area is well padded. There is also a comfy drawcord around the hood and top of the bag. The shell is polyester and the down is a 700 fill-power. For the price tag, this bag offers a lot of comfort.

HOWEVER It is not the lightest option available and it is quite bulky when packed too, so it’s not the best for lighter-weight backpacking. There is no shoulder baffle to lock in the warm air around your body, and as this is a wider and longer bag it will naturally feel cooler than a closer-fitting design, so you tend to need it fully battened down in cooler weather to stay warm. You don’t get the water-resistant down of higher-priced designs, and the outer is made of polyester rather than the more expensive but more durable nylon. The anti-snag zip design is better on some bags. You won’t get this level of space elsewhere but others are lighter.

VERDICT A spacious bag for maximum comfort, but the drawbacks are the increased weight and packed size.

Terra Nova Elite 550 £260

Terra-Nova.jpg
  • Lowest comfort temperature rating -5°C
  • Packed size 22x21cm
  • Weight 1256g (including 95g stuffsack)

IT'S GOOD The price is creeping up now but is still far more appealing than the higher-priced options. The insulation is 600 fill power down which is housed in a very robust and tightly-woven polyester, rather than nylon, to reduce costs. You also get an internal shoulder baffle with a drawcord and the hood is well packed with insulation. There is also a drawcord around the top of the bag and around the hood. The side zip extends halfway down the side of the bag, rather than being full length, to save weight, and some reflective piping makes it easier to find the zip at night. The stuffsack contains compression straps.

HOWEVER To keep costs down there are drawbacks. This bag is relatively heavy, in part due to the use of 600 fill power down rather than more efficient 700 or 800 fill power down. Also the polyester outer shell is quite heavy compared to the lighter nylons used on the higher-priced bags. The side zip is only half length, so if you use this on hotter nights your feet may get overly warm and you won’t be able to vent them. The bag is slightly smaller than others too, at 210cm long and 73cm at the shoulder. Higher priced bags also use down that has
a water-repelling treatment to maintain performance better when it gets damp.

VERDICT The price is attractive but the bag is heavier when packed and it has only a half-length side zip, as well as being slightly smaller than some.

Vango F10 Vulcan -7°£280

Vango.jpg
  • Lowest comfort temperature rating -7°C
  • Packed size 25x18cm
  • Weight 962g (including 44g stuffsack)

IT'S GOOD The packed size and weight of this bag are slightly less than some others, and the comfort limit is also a lower offering than normal at -7°C. So what’s going on? Well, the Vulcan uses a V-baffle construction with Hydro-barrier 700 fill power down, which is treated to help maintain performance if damp. There’s also an internal Thermal Reverb aluminised reflective liner within the bag to reflect heat back to the user, while the elastic seams appear to hug the bag closer to the body. These features help give a good temperature rating for the low weight. The bag has a good size, of 220cm long by 80cm wide, and I found all this came together well for a comfy sleep. 

HOWEVER The hood and foot construction aren’t quite as elaborate as some others, so while these areas work well enough others have more complex designs to better ensure that the insulation is well placed. The hood in particular doesn’t fit as neatly as others. The outer shell is made from ripstop nylon, which is thinner and lighter than other options. This saves weight but does mean you need to treat it with more care. Some bags have added benefits, such as volume adjustment on the hood or a fleecy chin area. The price tag is quite high too, so you need to decide if that low weight is worth it to you.

VERDICT  Ideal for backpackers wanting to save a few grams, but some details aren’t as good as those on heavier bags.

Marmot Hydrogen £300

Marmot.jpg
  • Lowest comfort temperature rating -4.8°C
  • Packed size 22x15cm
  • Weight 672g (including 20g stuffsack)

IT'S GOOD The Marmot Hydrogen has an excellent weight for a sleeping bag of this temperature range and at this price tag. But what is really important is that the details are great too. You get 800 fill power down, which carries a Down Defender treatment to reduce the impacts of moisture on its performance. The bag has a Pertex Quantum shell with a side zip that is specially designed to be less likely to snag, and does appear very effective. The hood design fits closer than others and is very comfortable around the face, while the foot box is also well-shaped thanks to some extra panels. It is hard to justify paying more as any improvements gained are small. 

HOWEVER The bag is slightly narrower than others, being 76cm at the shoulder. It also tends to taper a little more than others toward the feet, but at 220cm the length is good. Also while the hood and top of bag is nicely packed with insulation there is no additional shoulder baffle, so it is necessary to fully tighten down the top of the bag to lock in warmth. To do this there is just one drawcord which goes around the brim of the hood, rather than a cord that extends across the top of the shoulders at the top of the bag. This does work, but others are more adjustable. 

VERDICT Superb weight for the temperature and price, but personal preferences will dictate if the hood and shoulder design is right for you.

Montane Direct Ascent £320

Montane.jpg
  • Lowest comfort temperature rating -5°C
  • Packed size 23x21cm
  • Weight 1181g (including 63g stuffsack)

IT'S GOOD A well-established bag that has proven itself over a number of years. It has the key features a 3-season camper needs, with a good temperature rating, a good weight and a good packed size. The insulation is 800 fill power down and this is held in place with trapezoidal baffles to limit cold spots at the seams. The shell and lining are made of Pertex Quantum nylon. There is a unique volume adjustment on the back of the hood, so you get a jacket-style hood fit. The baffle is well filled and can be adjusted, while extra panels in the foot allow more space without compressing the insulation. 

HOWEVER There is not a lot wrong here, but bags with hydrophobic down will maintain a better performance when damp. The bag’s size is 205cm long by 78cm wide, which is slightly shorter and more narrow than some sleeping bags, so some people may feel other bags are more appropriately-sized for them. Some bags are also a degree warmer but for 3-season use this bag is still fine of course. This is not the lowest priced bag available, but if you compare the details it does have a few extra benefits that others lack, such as a microfleece panel around the chin and that great hood and shoulder baffle.

VERDICT A great backpacking bag, with the drawbacks being others have more water-resistant down, some are slightly lighter and others are lower in price.

Criterion Quantom 350 £345

Criterion.jpg
  • Lowest comfort temperature rating -6°C
  • Packed size 18x16cm
  • Weight 710g (including 19g stuffsack)

IT'S GOOD Check out the weight, check out the pack size and then check out the temperature rating. This bag has it all for anyone wanting to travel light and stay warm. So how is it done? Well, firstly you are getting 870 fill power down, which is more efficient than, say, 700 fill power down, meaning you need less of it to stay warm. You also get a very thin Pertex Quantum nylon outer, which all helps to save weight. Trapezoidal and box wall construction keeps cold spots at bay along the seams. Other features are kept to
a minimum to save on weight and size, but fundamentally this sleeping bag provides a comfy night’s sleep. 

HOWEVER  With some other bags you get a more water-resistant down and also a more elaborate anti-snag baffle on the zip, so some more care is needed here.
I also noticed that some bags have more insulation in the hood, and the drawcord around the hood is less well protected too – so others are more comfortable in the head area in general. There is a shoulder baffle, but some other bags have a more extensive design. Some also have a more elaborate foot box design. At 217cm long and 75cm at the shoulders it is slightly smaller than some. These details may not be important if weight is your main priority, but the price tag may still be a concern.

VERDICT An ideal bag for lightweight backpacking, but heavier bags have benefits including a lower price tag.

Thermarest Parsec 20 £350

Thermarest.jpg
  • Lowest comfort temperature rating -6°C
  • Packed size 24x22cm
  • Weight 1043g (including 88g stuffsack)

IT'S GOOD The Parsec 20 is new for 2018 and has been designed to be attached to a Thermarest mattress via two removable connectors, which means you are not having to carry a full bag of insulation as the base of the sleeping bag is insulated by being attached to a sleeping mat. It also means you cannot slide off the mat when inside the bag. The bag is insulated with Nikwax-treated 800 fill power down to resist dampness, and a Thermacapture lining traps radiant heat. The half-length side zip has a very good baffle inside, there is a huge shoulder baffle and the hood is very well insulated. The shell is polyester, with a very good water-repellent treatment.

HOWEVER This is not quite the lightest and most compact bag, and this is due to not having the thinnest and lightest nylon shell - as well as appearing to have a little more insulation in the hood, the side zip baffle and the shoulder baffle than some other bags. The removable connectors for attaching the bag to the mattress are quite bulky and weigh 40g too, so you could ditch these. Some bags have a shoulder baffle drawcord and also a hood that fits a little neater, with a down-filled baffle under the hood drawcord, so this area isn’t the absolute best. Also that side zip is not full length, so you cannot vent your feet.

VERDICT A warm bag with a good weight and attaches to a mattress, but the short side zip may not be ideal.

Lightwave Firelight 450 £549

Lightwave.jpg
  • Lowest comfort temperature rating -5°C
  • Packed size 20x18cm
  • Weight 756g (including 15g stuffsack)

IT'S GOOD 

This bag uses 900 fill power down, and appears to have more insulation and be slightly warmer than some other bags at this weight and temperature rating. Importantly you also get an exceptionally good weight and small packed size and yet you still get a well-stuffed hood area and a full shoulder baffle, which is better than slightly lighter bags. Slant wall construction is used to reduce cold spots and the shell is made of Pertex Quantum nylon. A nice benefit with this bag is that the side zip is placed on the top edge to reduce cold spots. So with its good warmth and minimal packed size this is a winner for backpacking when weight is important.

HOWEVER The huge price tag is an obvious issue with this bag, so you need to be keen to warrant the cash. Also this bag’s dimensions are 210cm long by 76cm wide at the shoulder, so it is slightly smaller than some other bags, which taller walkers may need to consider. Yes, you do get a shoulder baffle that is well-filled – but you don’t get a drawcord adjustment, as is standard on heavier bags. Like other lightweight bags the hood drawcord is not as well insulated as others, so it can dig in a little. Also the side zip doesn’t benefit from the elaborate anti-snag strips found elsewhere, so a little more care is needed. 

VERDICT Exceptionally good weight and warmth for lightweight backpacking, but the price could scupper it.

Vango Supernova 5000 2011

The Vango Supernova 5000 explodes out of its stuffsack and is the closest you’re going to get to down luxury in a synthetic sleeping bag. The hollowfibre insulation lofts (fluffs up) extremely well, and you get a good compression sack, an inner pocket and a two-way zip with a good baffle running down to the feet to allow it to be opened out in warm weather. But what really makes this bag comfy is the Thermal Embrace System, where the elasticated inner lining is brought snug to your body to keep warm air where it should be, next to your body. Add this to an exceptionally well-fitting hood and shoulder baffle, and you have one of the warmest bags on test. However the Vango Supernova 5000 is big and heavy, so you’re paying for all that warmth and loft when carrying it. This is fine for campsites, but will be hard work for camping up high. Also, the large packed size means you’ll need a large rucksack to carry it, along with the rest of your kit. If you can afford it, there are smaller, lighter and more versatile sleeping bags on the market.

The Vango Supernova 5000 is an innovative sleeping bag offering great-value warmth and function in a soft, luxurious package, and it won Trail’s ‘Best Value’ award. It’s big, though, and heavy.

Vango Supernova 5000 2010

The steam from my mug of morning tea drifted up through the unzipped doorway of my tent. The sun was rising over a perfect wild camping morning. When everything goes well, there is nothing more idyllic than waking from a good sleep high on the mountains. The problem is that the weatherman’s forecast is never that reliable. Knowing how much gear to take wild camping to stay warm and comfy is a balancing act between carrying so much that your rucksack is uncomfortably heavy and packing too little, which can result in a sleepless night. The key to staying warm at night is all about efficiency. The more efficient your gear the warmer you will be without having to carry extra kit.
Vango’s new Supernova 5000 sleeping bag is designed to maximise the efficiency of its insulation. It features Vango’s Thermal Embrace System; elasticated threads on the inside of the bag. These threads cause the bag to fit closer to the user than one with the usual non-stretch threads. The lining is pulled comfortably close to the curves of the body, holds the insulation closer to you too and does not allow warm air to billow out of the bag when you move. Equally the insulation inside the bag is allowed more space to ‘loft’ (fluff up) due to the stretch inner hugging the body. The result is a bag that works far more efficiently than a conventional sleeping bag – so it should keep you warmer. There are other bags that use stretch systems, such as the Mountain Equipment Dreamcatcher range and the Mont Bell Down Hugger. It is basically the same system but they put stretch on the outside too, which is a drawback as that compresses the insulation. Vango’s Thermal Embrace System is better as the stretch is only on the inside so the insulation has more space to loft.
I used the new Supernova 5000 sleeping bag in early November. It is insulated with synthetic hollowfibre, so it is not as light or as compact as an equivalent down-filled sleeping bag, but at £90 it is far easier on the wallet.
The bag erupted from its stuffsack effortlessly and immediately felt big, warm and cosy. It is rated as being comfortable down to -8 to -12 deg C, which is ideal for milder winter conditions. Annoyingly, Vango describes this as a 5-season bag, but I’m sure most people would describe it as a 3- 4 season bag.
I found it comfortable, though, with a great side zip that did not snag on the large baffle. The hood fitted well and was easily adjusted. A large shoulder baffle enhanced efficiency further by preventing warm air from escaping the bag when the hood was not fully tightened. 
The Vango’s new Supernova 5000 is definitely a step forward in efficiency, and I look forward to seeing the Thermal Embrace System on their down bags too, and more stretchy bags from other brands in the future. Those elasticated threads cannot guarantee the weather, but at least they do mean the sleeping bag is doing more than its fair share of work to keep you comfortable and cosy at night wild camping in the winter hills.

Verdict
The Vango Supernova 5000’s internal stretch baffles increase insulating effect; good side zip; good hood. But the weight and packed size are high compared to higher-priced or to down-insulated alternatives. In summary, the Vango Supernova 5000 is an excellent bag for year-round use for those on a tighter budget, but packed size and weight are always the drawbacks at this price.

Vango Summit 5000 2009

The Vango Summit 5000 is a very slim-cut 3-season synthetic sleeping bags that features on the Duke of Edinburgh’s Award recommended kit list. The two-way zip is unusual as it runs from the hood all the way around the foot box. This allows you to vent your feet as well as open the bag out flat like a duvet. The zip is draught-baffled along its whole length and runs smoothly. The hood is well-shaped with different cords for both halves, plus a drawcorded shoulder baffle. There is a large internal chest pocket, and the fabric feels fine against bare skin. The bag feels warm and the outer is very water-resistant. But it’s a very narrow bag indeed, especially at the legs, and I actually found it too tight to sleep in. This then made the zip hard to operate because of the restriction on movement inside. The insulation feels a little lumpy with inconsistent thickness throughout the bag.

Verdict: The Vango Summit 5000 is a 3-season synthetic sleeping bag that would be better suited to smaller-framed users, as it’s very narrow, while the slightly warmer comfort temperature has made the bag heavier than expected for its size.

Vango 8000 ASC

This 3-season synthetic sleeping bag has a -3 deg C comfort temp limit but feels warmer; compression stuffsack; substantial shoulder baffle; substantial zip baffle; outstanding water resistance; hood has lots more insulation than many; easy drawcord adjustment; zip does not snag. But 2000g is quite heavy, and this bag feels warmer than its temp rating; closer, more restrictive size than most others.

Verdict: Buy it if you want an excellent, warm, close-fitting bag and weight is not your top priority.


Vango Viper 500

This is a heavy sleeping bag from Vango with 90 per cent down content, making it really warm. The deep hood is very snug and the shoulder baffle works well and is easy to adjust from the inside. The soft feel of the fabric is great, and the two-way zip and security pocket are also useful.

Verdict: Heavy, but good quality and very warm.
