Osprey packs are best known for their incredible levels of comfort, and the Stratos is no exception. Throw this pack on and you get great airflow from the AirSpeed back system, which means you don’t feel too sweaty. But the pack also fits closely and really hugs the body, making this a very stable carry too. In terms of comfort this is the best sack on test. The body of the Stratos 34 has a ziparound front panel opening to the main compartment, which I don’t like as it’s harder to stuff extra items at the top than it is with a lid and if the zips break then the whole rucksack is useless. If you do want a lid the Stratos 36 and the women’s Sirrus 36 (not featured here) do have a one. On the Stratos 34 there is one handy front and one large top zipped pocket, and these are well-designed. The side wand pockets and compression straps work well with trekking poles, although you also get a unique Stow On The Go method of attaching poles to the shoulder straps and the base of the pack too, which works okay. There is a small pocket on the Osprey Stratos 34’s shoulder strap that‘s good for phones and smaller GPS units, but it’s too small for some, which is a pity.
Capacity 34 litres
External zipped pockets 2
Wand pocket yes
Hydration pocket yes
Floating lid no
Back lengths S, M, L
Women’s version yes (Sirrus 36)
The Osprey Stratos 34’s superb AirSpeed back system is wonderfully comfortable, but the ziparound front opening may mean some will prefer the lid design of other Osprey packs.
