Osprey Ultralight Liquids Pouch

The Osprey Ultralight Liquids Pouch is a small clear pouch built primarily for carrying liquids in carry-on luggage under TSA rules, though it works just as well as a lightweight toiletry bag on the trail. The body is recycled ripstop nylon laminated with TPU film, giving it enough water resistance to contain a leaking bottle of sunscreen or shampoo without soaking through to the rest of your pack. At just 48 g and 1 litre of capacity, it barely registers on a gear list, yet its broad base means it stands upright on a shelf or a rock by the tent — unlike a typical flat ziplock bag. The clear material also lets you spot what's inside without digging through it. It's best suited as a small-liquids and toiletries organizer rather than a general-purpose storage bag — for bulkier or heavier items, a sturdier pouch is the better choice.
