Versatile water carrier, also 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 63mm 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 use. 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.
