Osprey Packs

Sirrus 24L Backpack - Women's

What Our Gearhead® Experts Are Saying:

"I put the Osprey Packs Sirrus 24L Backpack on for the first time on a long ridge hike and the AirSpeed back panel was immediately noticeable in the best way possible. The tensioned mesh keeps the pack off your back entirely, and on a warm day that airflow channel makes a genuine difference in how comfortable you feel at mile ten versus mile one. The women's specific hip belt and shoulder straps kept the load sitting exactly where it should without any adjustment stops along the way."

There is a moment on a long trail where a well-fitted pack stops registering entirely, where the weight transfers to your legs and the ventilation does its job and you just move. The Osprey Packs Sirrus 24L Backpack gets you to that moment faster than most, built around an AirSpeed suspension system that keeps the pack tensioned away from your back and the load moving efficiently toward your hips rather than pulling down on your shoulders.

Osprey constructed the Sirrus 24 with aluminum stays behind a tensioned mesh back panel that simultaneously manages load transfer and creates a continuous airflow channel between the pack and your back, a combination that makes a meaningful difference on sustained climbs and warm weather days alike. Women's specific Spacer Mesh shoulder straps and a padded hipbelt work together to place the load where it belongs anatomically, and the 210D and 420D nylon construction handles the kind of repeated use that a go-to daypack sees across a full hiking season. An integrated rain cover deploys in seconds when the weather shifts, ice axe and trekking pole attachments free up hands on technical terrain, and compression straps cinch down a lighter load without leaving the pack bouncing. At 24 liters the Sirrus lands in the sweet spot for a full day in the mountains, covering hiking, backcountry touring, climbing approaches, and travel with equal competence.
