Osprey Stratos 24 Backpack Review

The Osprey Stratos 24 and women’s Sirrus 24 are ultra-comfortable and ultra-breathable backpacks. They're great for day hikes in Georgia’s warm climate.

Avid hikers, backpackers, and cyclists, we’ve long been fans of Osprey’s backpacks, and the Stratos 24 marks the fourth bag in our backpack collection from Colorado-based Osprey.

Long-time fans of Osprey’s design, durability, fit and comfort, we’re equally impressed by the Osprey Stratos 24 and women’s Osprey Sirrus 24 – and in love with their innovative breathability.

Osprey Stratos 24 review

In Georgia’s warm, humid climate, airy backpack ventilation is something I’ve longed for on the trail. The coverage of most backpacks leaves puddles of sweat on my back, which is equally uncomfortable and chilly when temperatures drop later in the day. The Osprey Stratos 24 combines a curved, lightweight aluminum frame with an open, perforated back panel, leaving space for a ton of airflow between the pack and my back. The result? An incredible amount of ventilation.

The Osprey Stratos and Sirrus backpacks reflect attention to detail in design. They’re lightweight and comfortable, but equally durable. We’ve trekked thousands of miles in our Osprey packs, including the Aether 70 and Talon 33, and they’ve held their suspension, shape and stitching flawlessly.

The pack’s curved aluminum frame arcs the pack’s back panel away from my back, slightly reducing the pack’s volume but still retaining a respectable 24L cargo area. The interior is roomy enough to stow gear for an average day hike: a hydration pack, favorite gear on my hiking gear list, extra layers, a waterproof jacket, lunch, and snacks. The internal hydration pack storage sleeve pairs really well with the lightweight (and frameless) Osprey Hydraulics LT 2.5L hydration reservoir.

Weighing in at 2 lbs 4 oz, the Stratos 24 isn’t an ultralight pack: the frame and suspension add a some weight. But the pack is lightweight, comfortable and balances its cargo weight well. To me, the pack’s comfort far outweighs the frame’s negligible extra weight.

The backpack’s straps and hip belt are perforated and cushy, and provide great support for moderate weight loads.

The pack’s top zippered pocket stores gear for easy access, like a base layer for warmth, a snack, keys, or other small gear. And two side pockets keep bear spray or water bottles within an arm’s reach. (The side pockets are also useful for carrying a tripod – they fit my Gitzo GT1544T Traveler tripod with two tripod legs in the pocket, and the pack’s adjustable loop clenching the tripod’s top.)

The Stratos 24’s design packs in additional features, including a rain cover in case of a drizzle on the trail. The pack features large zipper pulls for fast access to the pockets, and an integrated trekking pole loop. And hipbelt pockets offer quick access to small gear, like a GPS or phone.

Osprey Stratos 24 Review: Bottom Line

The Osprey Stratos and Sirrus packs use an innovative ventilation system to increase breathability on warm-weather trail days, and their suspension and padding stays comfortable on 12+ mile hikes. I love the performance, comfort, stability and breathability of this pack, and it’ll be with me on many future trails.
