The HydraPak Seeker™ 3 L is a rugged, ultra-light (92 g) water storage bag made from RF-welded TPU that collapses to fist-size when empty but holds 3 L when full. It features a tethered 42 mm leak-proof screw cap compatible with 42 mm filter caps. The low-profile handle and dual lash points allow easy attachment to packs or gravity filtration setups. The large 42 mm opening makes filling easy, and the bag packs into the included storage pouch.
