What Our Gearhead(R) Experts Are Saying: "The Sirrus 34 is my go-to for longer day hikes or minimalist overnights. The AirSpeed suspension keeps me cool even when it's loaded, and the panel access is a dream when I need to grab gear mid-hike. The included rain cover is a lifesaver on those unpredictable mountain days." When we're packing for big days that demand a little extra gear, the Osprey Sirrus 34L Backpack delivers the perfect mix of comfort, organization, and weather protection. Designed specifically for women, it offers a ventilated AirSpeed(TM) suspension system that keeps air flowing while distributing weight evenly for a light, stable carry on rugged terrain. The panel-loading main compartment makes packing and accessing layers or snacks a breeze, while a lower zippered compartment keeps gear-like a sleeping bag or extra clothing-separate and organized. External pockets and trekking pole attachments keep essentials handy, and the included rain cover ensures we're prepared for sudden downpours. Built from 100% recycled bluesign(R)-approved nylon with PFAS-free DWR, the Sirrus 34 is a sustainable, dependable pack for all-day adventures and fast overnights.
