35L Ultralight Dry Sack + Window protects large loads with waterproof clarity and smart storage
What Our Gearhead® Experts Are Saying:
"I use the 35L Ultralight Dry Sack for big adventures—multi-day river trips, overseas travel, or when I need to separate bulkier gear in my pack. The see-through panel is a game-changer when you’re living out of your bag. It's surprisingly light for its size, and the waterproofing has held up in some serious weather."
When we’re packing for days—maybe weeks—off the grid, we need storage that’s not only reliable but also smart. The Osprey 35L Ultralight Dry Sack + Window is exactly that: a lightweight, waterproof dry sack built for larger loads and dialed-in organization. Whether it’s basecamp layers, sleeping systems, or food for the crew, this sack keeps gear dry, visible, and ready at a glance.
Made from bluesign® approved recycled ripstop nylon and treated with a PFAS-free DWR, it's sustainably built without sacrificing durability. The clear window eliminates the guesswork when rummaging through your pack or dry bag pile, and a roll-top closure with welded seams ensures full protection from rain, splash, or snow. From thru-hikes to river crossings to remote travel, this dry sack is designed to haul and protect the essentials that matter most.
