The Osprey Pack Pocket Waterproof is a compact storage pouch designed to keep small essentials close at hand while you’re on the move. With its 1-liter volume and fully waterproof build, it ensures snacks, tools or electronics stay dry without the bulk of a larger bag.

Its recycled 400D nylon with TPU double coating sheds water and holds up to rough treatment, and its 11 x 19 x 4 cm footprint tucks easily into your main pack or hipbelt pocket. At just 49 grams, it hardly registers on the scale, so you can carry your essentials in a weatherproof layer without adding noticeable heft.

In fabric terms, 400D (denier) refers to the thickness of the yarn: higher denier means tougher threads. The TPU (thermoplastic polyurethane) coating bonds to the nylon to seal the weave, making the material impenetrable to water while preserving flexibility.
