Osprey Sirrus 50

Best Women’s Weekend Warrior Pack

While 50 liters is teetering on the edge of being too little for multi-day treks, the Osprey Sirrus 50 is the perfect pack for short adventures, and we definitely recommend the 24- and 36-liter versions for day hikes. The Airspeed Suspension System is completely customizable, and the hip belt placement keeps the weight off your back.

Pros: The Airspeed system is a thing of beauty. While the torso is not incredibly easy to adjust (held tight by Velcro), every other angle and point of pressure can be dialed. The hip belts are extremely comfortable, even with a fully loaded pack. Duel hip belt zippered pockets were appreciated, but testers noted their volume is less than other packs reviewed. Brain, side stuff and front stuff pockets provide quick access, and an additional zippered pocket on the front of the stuff mesh pocket was a clever addition.

Cons: The sleeping bag compartment seems a bit small, so unless you have a compact, low insulation bag, you may have to repurpose that compartment—which is rarely a huge problem. The pick-me-up handle is awkwardly placed and rendered all but useless when the brain is closed.

Tester Comments: “I can’t believe how compact this 50-liter pack is—it looks like the same size as my 30-liter. And can we talk about the suspension system? It’s pretty amazing. The hip belts sit perfectly, and I’ve this is best I’ve even tighten and dial in a backpack. This is one of the most comfortable backpacks I’ve ever worn.”

Bottom Line: This 50-liter Osprey backpack is the perfect size for one or two nights, especially with a full pack, as the suspension system is top-notch.

Best for: Overnighters and weekend warrioring
