Osprey Sirrus 24

The Sirrus is the women's-fit Stratos and the ventilated counterpart to the Tempest: a suspended AirSpeed mesh panel rather than contact foam, plus an included rain cover and a heavier 210D honeycomb shell over a 420D base. It is the day pack in Osprey's women's line for hot weather and long days.

Pros

  • 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.

Cons

  • 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.

Daypack

The Tempest is the women's-fit Talon and Osprey's technical daypack. The 2025 redesign moved the line to an AirScape ridged-foam backpanel that sits against the back rather than a suspended mesh, which keeps the load close and stable for scrambling at the cost of some airflow. It runs 11, 22 and 33 L.
