Osprey Stratos 24
#9 — Best Ventilated Suspension

Osprey Stratos 24 Review (2026)

A suspended mesh back panel that keeps your shirt dry in July

★★★★★
8.6/10
Reviewed by William • Updated August 2026 $170

If your complaint about daypacks is a soaked shirt, the Stratos solves it. The AirSpeed trampoline suspends a tensioned mesh panel away from your back so air moves freely behind the pack, and in humid summer heat the difference is not subtle. The cost is weight and stability: at 2lb 6oz it is the heaviest pack here, and the curved frame pushes the load away from your back, which reduces stability on scrambles and makes the pack feel larger than it is.

What Sets It Apart

Mid-Atlantic summers are the argument for this pack. At 88°F with high humidity, a flat-panel pack means a completely soaked back within a mile; the Stratos leaves a dry strip and it changes how a long day feels. On cool days or technical ground the extra 7oz and the reduced stability are hard to justify.

Common Questions

Is a trampoline suspension worth the weight?
In hot humid conditions, for most people yes. In cool weather or on scrambles it is a net negative.
Does the raincover actually fit?
Yes, it is sized for the pack and stows in a dedicated bottom pocket. That is one fewer item to buy separately.
