Best running hydration packs and vests of 2024

Nothing is more important than staying hydrated, especially out on the trails. Here are some of the best packs to do just that.

Best running hydration packs and race vests tried and tested

As trail runners, we all understand the importance of our hydration packs. It’s got to feel just right both in terms of fit and weight, but also ease of access.

Especially because not all of us are blessed with gymnastic skills on the move. We don’t want to spend ages contorting at the hip and fiddling around looking for that all-important water flask, and we especially do not want a bag that requires stopping and taking off just to fish out an energy gel.

Front pockets, hip stashes, somewhere for a phone and, of course, a system for keeping hydrated on the move. And preferably enough storage to carry a waterproof running jacket and some sweets. Those are the qualifying factors for our shortlist – good features and an even better fit is what wins around here.

What are the best hydration packs and vests at a glance?

Best in test – Scott Trail TR 10

Best for sustainability – Patagonia Slope Runner Vest

Best carrying capacity – Montane Gecko VP 20L+

We’ve selected the best hydration packs for a range of running styles, from short and fast woodland jaunts to monstrous mountain ultras. So, keep that in mind when you make your final choice. Just as you'd ensure you had the best ultra running shoes for 150km race, you'll want to find the best pack for your style of run. Sprinting over Skiddaw in the pouring rain in February has very different storage requirements than a leisurely June jog… for most of us anyway.

How we tested these hydration packs and vests

These running packs were tested by a range of dedicated members of the LFTO Testing Team. This includes our much beloved Scottish contingent, plus Country Walking editor, Nick Hallissey, who (after reviewing his first pair of trail running shoes) has betrayed his love of walking and opted for a new hobby that's a little higher tempo. We put these packs through their paces at events ranging from Nick's local 10k to Meg's Yorkshire Peak ultra marathons. Check out our full page to learn more about how we test.

Scott RC Running pack gear of the year winnerLFTO

First things first, this bag looks great. It's also fantastically light, weighing in at only 110g (less than the two bottles that come with the pack). Surprisingly at that weight it also has a 10 litre capacity bladder pocket which, if fully filled with water, would obviously add some heft. But a bladder isn't even required since the flexible TR 10 also has room for flasks.

Speaking of which, there are no less than 6 pockets on the front of this bag. They follow the standard pattern; two at the top for Gels, Middle two reserved for your 500ml flasks. The flask pockets come with fixation loops so if you do something silly like fall into a stream whilst running, the bottles won't go astray.

Two lower pockets are for items such as gloves, headscarf, sweets etc. The material here is said to be stretch fabric but there's not a huge amount of give; we'd prefer an elasticated material to keep things slightly more secure. This is only a minor gripe however.

If six front pockets weren't enough, you have zip pockets on either side of the waist and they are large enough to stash a mobile phone securely. No space is unused on this pack, its ergonomic design really does shine. The pack fits great and the two straps across the chest are easily adjusted.

This bag will catch the eye for those looking for a light race pack and will also accommodate a longer run across a day. It might not be the cheapest bag but it covers so many aspects for trail runners it could be the only one you need.

We absolutely love the Patagonia Slope Trail Runner Vest. It’s everything we hoped for and more from a brand with such a strong environmental reputation. The vest is incredibly comfortable, thanks to its lightweight ripstop mesh and durable water repellent finish. It also fits so well that we sometimes forget we’re wearing it, even on long, hot runs. The adjustable design keeps everything secure, and we’re impressed by how stable the water flasks stay in the low-profile front pockets.

The thoughtful details really stood out to us—Patagonia included two 500ml HydraPak flasks, and the array of pockets is perfect for snacks, gels, and extra layers. The zip pocket for valuables is a great touch, too. Plus, we appreciate that there’s room for a hydration reservoir for very long outings where a litre just won't cut it.

On the sustainability front, Patagonia doesn’t disappoint. We’re big fans of their commitment to recycled materials and fair trade practices; while the vest does show a slight stretching over time, we’re confident in its durability, especially with the Ironclad Guarantee.

Yes, the price is steep at £150, but in our opinion, it’s worth it if you want a vest that’s built to last. Patagonia’s Slope Runner Vest is a fantastic investment for any serious runner.

Montane Gecko VP 20L running vestLFTO

The Montane Gecko VP 20L+ is built for runners who need serious capacity without sacrificing comfort, ideal for longer adventures that might involve a bivvy, bothy, or even multi-day hut-to-hut runs. This pack has ample space for essentials like a compact sleeping bag, fleece, lightweight waterproof, snacks, phone, keys, and a head torch, making it versatile enough for both day-long runs and minimalistic overnight trips.

Storage options are well-organised, with a spacious main compartment, a zipped security pocket for valuables, double-drawcord holders for poles or an ice axe, and stretchy front pockets perfect for quick-access items like gels or bars. Montane’s design philosophy of “wear it, don’t carry it” rings true; the Gecko clings comfortably to your body, supported by a broad Velcro strap over the abdomen that keeps loads secure even on rocky trails. However, when the 500ml bottles are full, there is some sloshing and slight movement, though it’s minor compared to other packs of this size.

At 420g (including bottles), the Gecko is lightweight, compressible, and offers decent ventilation, though its mesh back panel doesn’t breathe quite as well as the Arc'teryx Norvan’s. That said, the softer and lighter materials make it easy to pack down when you don’t need full capacity, and padding around the lumbar area offers extra comfort on the go.

While some may find it a bit more complex than Montane’s previous Via Fang vest, the Gecko VP 20L+ achieves the ideal balance between trekking-pack capacity and running-vest comfort. For those willing to trade a bit of minimalism for extra carrying capacity and thoughtful design, the Gecko is an impressive companion on long, challenging runs or ultralight trekking excursions.

Best for durability

Expert rating:

Price: £178.99

The Camelbak Apex Pro 12L running vest is a high-quality hydration pack designed for athletes and trail running enthusiasts, especially for challenging environments like the UTMB series. Built with durable nylon, it holds up well against rough conditions, although it’s slightly heavier and less breathable than some competitors. Despite this, the vest remains comfortable, thanks to its four-way stretch material and adjustable straps.

The pack features a large main compartment, a smaller waterproof pocket, and a mesh section for a 2L water reservoir (sold separately, which is a bit of a gripe seeing as this pack dosen;t come cheap). A feature we really like, however, is the removable trekking pole quiver, which includes drainage holes for wet conditions. Safety is prioritised with RECCO reflector technology and multiple reflective patches throughout the vest's construction.

The pack includes two 500ml quick stow flasks in front pockets, though these flasks may feel undersized for a 12L pack. Additional storage options include a zipped pocket, a key clip, and a pass-through pocket for extra layers. Retailing at £140-£150 (but with a very high RRP of £175), it competes with the Salomon Advanced Skin 12 but offers better value with the included pole quiver.

Sustainability efforts are present here, but transparency about specific goals achieved is lacking. Tested on the Yorkshire Moors and Dales, the Apex Pro performed excellently, proving itself as a reliable, durable, and comfortable choice for long-distance mountain adventures. Despite its high price, the Camelbak Apex Pro 12 justifies its cost with its practical features and overall performance - this vest will last years, if not decades.

Best for race day

Expert rating:
4.0

The North Face Flight Race Day Vest 8L is a lightweight running vest, coming in at just 200g, enabling high performance on the trail. It first catches your eye in the sharp green colour, keeping you uber visible on the trails (although it is also available in black if bright colours aren’t for you), with a further attractively reasonably price tag.

It is constructed from high quality quick drying wicking material with a water repellent DWR finish, keeping extra water weight to a minimum when you undoubtably get caught in the rain whilst out in the hills. But even during hot weather runs, the material breathes well, and you barely notice you are wearing a pack. The pack also comes equipped with a whistle to fulfil race day regulations.

The North Face Flight Race Day Vest comes equipped with plenty of storage options with a handy zipped phone pocket on the front, along with easy access side pockets for gels/snacks or small layers, as well as the larger back pocket for larger extra layers. There is also a lower back pocket, ideally suited for stashing running poles or a quick access layer.

 A really nice feature of this pack is that it comes with two 500ml soft flasks included which are easily attached to the bottom of the pockets via a flexible leash system, which keeps the bottles secure on the go but also enables quick refilling. The flasks fit snuggly into their pockets and when secured properly, bouncing is minimal. The pack also is also hydration bladder compatible and a 1L bladder can be slotted into the large back pocket, secured by a sturdy clasp fastening system.

As an outdoorsy woman on the smaller side I often find the fitting of packs and vests quite difficult, however this vest fits just perfectly. As a size 8, I found the sizing of the XS vest to be a snug yet comfortable fit. The straps on the front are very easy to adjust and the clasping system is sturdy, and even with a full pack I found the ‘bouncing around’ of the pack to be extremely minimal. Although, general verdict on the internet suggests the Flight Race Day Vest runs large, so for a compact snug fit maybe it would be worth sizing down. Overall, the North Face Flight Race Day Vest 8L is a great pack for both the beginner and experienced trail runner.

Best for snack access

The Rab Veil 6L Lightweight Running Vest is is a brilliant bit of kit. The fit is snug, yet breathable, ensuring you remain cool even when the miles—and the sweat—start to pile up. Sure, it's not as lightweight as other vests on the market, but its features and design more than make up for it. Tested over the course of a damp British summer, we're impressed with its load capacity and well-thought-through features such as zipped pockets for keys and cards, plus bungee cords for your poles.

Pockets galore are the highlight here: perfectly placed and sized to hold everything from snacks to your phone without turning you into a pack mule. We especially like the stretchiness of the main pocket, which is a bit of a tardis when it comes to stuffing in insulation layers and packets of biscuits. The hydration system, featuring two soft flasks, is also easy to sip from without breaking your stride.

Once you’re off and running, the Rab Veil 6L becomes an invisible companion. It’s so lightweight that you might forget it’s even there, only to be pleasantly reminded by the easy access to an energy gel or a quick glug of water. Even in the rain, the vest’s materials shrug off moisture, keeping your gear surprisingly dry. The only thing we'd like to see improved is the sustainability credentials, as very little of the vest is made with recycled fabric.

Whether you’re tackling an ultra, or enjoying a leisurely Sunday jog, this vest is a reliable partner that’ll have your back through every mile. Strap it on, load it up, and hit the road.

Arcteryx Norvan 14 vestLFTO

With a generous 14L capacity, this vest easily holds a lightweight fleece, waterproof jacket, snacks, and a first aid kit. It even has space for stashing poles in the side wing pockets or securing an ice axe via front-panel drawcords, making it ideal for serious mountainous expeditions.

Two 500ml soft flasks sit on each harness strap, with additional storage pockets below for essentials like a phone, gels, and small items such as car keys or medication. The Norvan’s stability on the move is exceptional, with minimal bounce even when fully loaded. Its clever compression drawcords ensure it stays snug against your body, preventing the dreaded slosh of full water bottles.

Arc'teryx has equipped the Norvan with a rigid mesh back panel for enhanced breathability and support, though this adds some weight. The sturdy ripstop front panel further boosts durability, making it a bit heavier than some ultralight alternatives. However, this robust construction contributes to the pack’s impressive stability, even on rough terrain.

A thoughtful addition is the RECCO reflector, which can assist rescue teams equipped with compatible technology—widely available across Europe and used by UK Mountain Rescue.

The Norvan isn’t without its quirks. There’s no women-specific version of this 14L model, and the large wing pockets, while perfect for poles, aren’t suited to smaller items due to their taper. With a multitude of pockets, the vest’s complex layout requires some getting used to, especially if you’re prone to losing track of where items are stored. Despite these minor drawbacks, the Norvan 14’s balance of capacity, stability, and ruggedness make it an ideal companion for ambitious trail runs and alpine adventures.

Best energy gels for running

The stretchy material that largely comprises The North Face’s Summit Run 12 makes it a unique pick. Opting for a slightly unusual approach, this pack hugs around your torso with a light mesh which is breathable and accommodating for movement.  

This choice, however, comes at the expensive of sacrificing the tighter, more secure fit you might expect from a race vest. You may find the vest bounces around a bit if you aren’t lucky enough to match its dimensions perfectly. This is a rare moment where we'd advise you to go down a size if buying online. Still, the Summit Run is super comfortable to wear and has a large back compartment, as well as front pockets that can really stretch if needed.

Two 500ml flasks sit securely on each strap thanks to a leash system – though this isn’t super easy to use. A whistle is attached inside one flask pocket which is a nifty addition. If your phone is particularly large, you’ll have trouble squeezing it into the zip pocket which sits behind the flasks. There are a couple of quite sleek diagonal pockets for gels.

All in all, a comfortable pack that looks flashy (if you get it in black – we’re less keen on green) and fits snugly. Usually.

What to look for when buying a hydration pack

Best hydration packs for trail running reviewed LFTO
©Live for the Outdoors

Fit - Some models offer men’s and women’s versions which are important, but above all, you need to consider how the pack fits on your back and what is being offered in terms of support. How many straps are there? Do they easily fit around your waist and chest to minimise movement at pace?

Capacity - For longer races, you’ll need room for a variety of essentials ranging from a jacket, and an extra layer to medical kits and more. For shorter runs on your own, it’s possible you won’t need so much.

Storage - How many pockets are there? How many bottles can it hold? Is there room for your phone, gels, or money? All are offered to varying degrees, but some runners might also need pole storage facilities. And of course, consider ease of access on the move. You don’t want to be scrabbling around for your jacket on a steep ascent into the clouds – you need to be able to access it all instantly on the move, at pace.

Hydration capacity - Remember, water does weigh 2lb per litre, so the larger the capacity the more weight you’ll carry. Around two litres is probably the best compromise capacity for weight and speed.

Choosing your hydration system

When it comes to actually carrying your water, there are two primary approaches: flasks and reservoirs. You may have heard a reservoir referred to a bladder, Platypus, or Camelback (those two are actually brands of reservoirs). It's a flexible water storage container that is usually placed in the main compartment of your pack. It is usually made of durable materials such as BPA-free plastic, and is connected to a drinking tube (or flexi straw) which feeds out of your pack, attaches to one of the pack's arms, and then sits nearer the front of the pack in prime position for sipping as you run. This will typically be connected to a bite valve.

Best running bags packs for hydration trail 2023
©Live for the Outdoors

Ideally, you'd want your reservoir to have a vacuum seal, which means once you've sucked the initial air out of it via your straw, there's much less bounce and no audible sloshing about of water while you move. A bladder will have different ways to refill, but all must be watertight to work effectively. Some have a large top opening, like you'd see on a sandwich bag, while others have a smaller, circular screw-to-secure opening. The former is easier to refill and clean as its larger, yet the latter may be less likely to leak.

If a big bag of water isn't your style, then soft flasks are a great alternative. Unlike traditionally rigid and bulky water bottles, soft flasks are collapsible and typically made of lightweight, flexible materials such as TPU (thermoplastic polyurethane) or silicone. Soft flasks have less capacity than a reservoir, but they're much more versatile when it comes to placement and use. They're easy to access and refill on the go. Plus they're lightweight, compact, and the flexible body compresses as you drink to avoid any sloshing.

Top tip: Keep your soft flasks in the freezer to prevent mould and extend their lifespan.

Hydration Pack Glossary

Bite valve: Connected to the end of the drinking tube, this nifty feature is a staple for hydration packs as it allows runners to get at their water hands-free. The valve won't let any water pass through unless you bite or squeeze it, preventing leaks or spills during a run

Baffle: A partition or divider within the reservoir that helps maintain the shape and stability of the bladder. It prevents the water from sloshing or creating a large bulge, improving the pack's balance.

Yoke: The yoke refers to the portion of the hydration pack that covers your shoulders and upper back. It is typically adjustable and helps distribute the weight of the pack evenly.

Back panel: The padded area on the back of the hydration pack that rests against your body. It provides cushioning, comfort, and ventilation, allowing air to flow to help keep the back cool and minimize sweat.

Compression straps: Adjustable straps located on the sides or front of the pack that allow you to compress the pack's volume and stabilise its contents. They help prevent the water from sloshing around and maintain a snug fit.
