Versatile water carrier, usable as an outdoor shower. The Watercell X from Sea to Summit is a truly versatile water carrier: the leak-proof design with a wide opening makes filling, emptying, and drying easy and practical. The flat 63-mm multifunctional cap offers variable flow rates that can be easily controlled with one hand. The adjustable TPU strap system makes carrying and hanging simple, while welded tie-down points provide versatile attachment options for on-the-go. Made from RCS-certified, recycled, and bluesign APPROVED 400D nylon for flexibility, durability, and abrasion resistance. The robust, 3D-curved, RF-welded TPU construction is stackable, BPA- and PVC-free, and made without PFAS. With the included holder, which securely attaches to the carrying strap when not in use, it can be seamlessly transformed into a backcountry shower. Available in four sizes of 4L, 6L, 10L, and 20L.
