Pros & cons
Osprey Tempest 22
- ✓The AirScape foam panel keeps the load tight to the back, which is more stable than a trampoline panel when scrambling or moving fast.
- ✓At 35 oz it is 3 oz lighter than the men's Talon 22 while keeping the same feature set.
- ✓100% recycled 100D nylon with a dobby check ripstop resists tearing better than plain fabric of the same weight.
- ✓Hipbelt pockets are included, which many packs this size drop.
- ✓Three volumes from 11 to 33 L means the same fit scales from a summit push to an overnight.
- ✓The women's-specific harness is a genuine construction difference rather than a colourway.
- ✓Osprey's All Mighty Guarantee applies to daypacks as well as trekking packs.
- ✓Widely stocked, so trying one on before buying is realistic.
- ✗$175 is expensive for a 22 L daypack -- the REI Flash 22 covers the same volume at $60.
- ✗The AirScape foam panel ventilates noticeably worse than the suspended mesh on the Sirrus.
- ✗35 oz is heavy for 22 L; the Sportlite 25 carries 3 L more at 27.2 oz.
- ✗Osprey publishes no maximum load figure for the line.
- ✗The 11 and 33 L sizes have no independently measured weight published.
- ✗No rain cover included at this price.
- ✗The 2025 redesign changed torso sizing conventions, so older fit advice no longer applies.
- ✗Bear-canister fit is not stated, and the volume makes it academic anyway.
Osprey Sirrus 24
- ✓The AirSpeed suspended mesh is the best-ventilating back panel available in a women's daypack this size.
- ✓A rain cover is included, which the pricier Tempest does not offer.
- ✓A 420D recycled base is real reinforcement on the panel that takes the most wear.
- ✓The 15-19 in torso range is genuinely women's-specific rather than a shortened unisex fit.
- ✓Hipbelt pockets are included and sized for a phone.
- ✓A 36 L sibling shares the same suspension for overnight use.
- ✓210D honeycomb nylon is more durable than the 100D fabrics on the lighter Osprey daypacks.
- ✓Osprey's All Mighty Guarantee applies.
- ✗At 43 oz it is the heaviest pack in this comparison group and 8 oz heavier than the Tempest 22 for 2 L more.
- ✗$200 is high for 24 L, and the Gregory Juno 24 undercuts it at $150 and 31 oz.
- ✗The suspended mesh consumes depth, so usable volume is less than 24 L implies.
- ✗No manufacturer maximum load is published.
- ✗The 36 L size has no independently measured weight published.
- ✗The mesh panel is harder to repair in the field than a foam panel.
- ✗The frame makes it bulky to pack inside luggage.
- ✗Current pricing and the full Stratos/Sirrus size run are poorly documented; only the 24 and 36 could be confirmed.
