The Osprey Downburst 26L Men's Hiking Backpack is a fully waterproof daypack built for hikers who refuse to let weather dictate their plans. With an IPX5-rated main compartment and breathable AirSpeed suspension, this pack delivers the comfort and stability Osprey is known for while keeping your gear bone dry.
Osprey Downburst 26L: Waterproof Protection with Unmatched Breathability
The Downburst’s entire interior is protected by RF-welded, TPU-laminated construction, making it fully waterproof in everything from light drizzle to heavy showers. Meanwhile, the adjustable AirSpeed suspension provides category-leading fit, comfort, and ventilation, keeping your back cool even on humid trails. The quick-dry external materials ensure the pack sheds water efficiently, so you stay comfortable and your gear stays safe.
Intelligent Storage for Trail Essentials
Non-waterproof exterior pockets, including bottle pockets, a large backpanel stash pocket, and an external hydration sleeve, are made from breathable, water-shedding materials that dry quickly. The stiffened roll-top closure offers quick access to the main compartment while maintaining a watertight seal, and an ice axe/trekking pole loop with bungee tie-off adds versatility.
Built for Serious Day Hikes
Weighing just 3.2 lb, the Downburst 26L is light enough for fast-moving day hikes yet durable enough for rugged trails. The recycled nylon main body is bluesign approved, reflecting Osprey’s commitment to sustainability. Whether you’re hiking in heat and humidity or caught in a downpour, this pack is your reliable companion.
