Osprey Ultralight Dry Stuff Pack 20L

Some trips need a bag that barely exists until you need it. The Osprey Ultralight Dry Stuff Pack 20L packs down small enough to tuck into a suitcase, then unrolls into a roll-top, water-resistant daypack for day trips, beach days, or hauling souvenirs on the way home.

Rated IPX5 water-resistant (not submersible), this pack is built for humid, wet, or sandy destinations where a regular daypack would struggle. The roll-top closure seals out light rain and splashes, waterproof-coated fabric and seams keep the inside dry, and side stretch pockets hold a water bottle or quick-grab items. It's part of Osprey's Ultralight accessory system, designed to pair with a main travel bag rather than replace one.
