Osprey Atmos 35 Pack
The Atmos line is still in Osprey's range, revised many times, and the reason this review liked it is the reason it survived: the suspended mesh back panel genuinely works.
What the Anti-Gravity and earlier tensioned-mesh designs do: the pack body is held away from your back by a mesh panel under tension, so air moves and the load wraps rather than presses. On a hot day it is the difference between a wet shirt and a dry one, and it is Osprey's best idea.
35 litres is an underrated size. It is enough for a long day with extra layers, a summer overnight with light kit, or a cabin-sized travel pack. It is also the size most people skip on the way from a 20-litre daypack to a 60-litre expedition pack, which is a mistake, because it covers more trips than either.
What to check:
- Torso length, measured, from the bony bump at the base of your neck to the top of your hip bones. Osprey sizes on this, not on height.
- The hip belt on your hips, with the weight sitting there rather than on your shoulders.
- That the mesh panel suits you. A small number of people find the suspended design pushes the load away from their back in a way they dislike. It is worth loading one in a shop.
The thing worth knowing about the brand: Osprey's guarantee covers repair or replacement regardless of the pack's age, and they honour it. Over a decade that is worth more than any feature on the spec sheet.
The women's equivalent is the Aura, on the same frame with a different harness and hip belt. Try both.
