The Osprey UL Dry Sack window 3 waterproof storage bag lets you store and organise your belongings inside your backpack.
The transparent window makes it easy to see what is inside your bag, so you do not need to empty it to find your belongings.
Made from nylon, this storage bag is highly durable while remaining lightweight. The roll-top closure makes the bag waterproof, and the seams also have a waterproof coating.
This UL dry sack window 3 has a rectangular shape to make organising your belongings easier, with a 3-litre capacity.
This dry bag lets you protect your down sleeping bag, trekking clothes or electronic accessories from the weather.
The loop lets you hang the storage bag up, dry it or secure it when attached to a boat, for example.
