Building a hydration system for backpacking requires the careful fitting of various components: water bottles, storage systems, and water treatment methods. Minimizing the packed volume and weight of our hydration systems is a high priority for many of us. The Hydropak Seeker series water bags are durable, collapsible, and with their 37mm openings, compatible with the Katadyn Befree filters that many of us use.
The Hydropak Seeker is available in the Seeker 2L, the Seeker 3L, and the Seeker 4L models.
