The Sea to Summit Watercell X 10L Reservoir is an advanced, multi-functional water storage and dispensing system designed for the rigours of camping, overlanding, paddling, and backpacking. With a thoughtfully made 3D shape and radio-frequency (RF)-welded thermoplastic polyurethane (TPU) construction, this reservoir offers superior compactness and stackability, making it ideal for minimalist adventurers. Its flexible and durable 400D nylon external fabric resists abrasion and packs down easily, while the Bisphenol A (BPA) and Polyvinyl Chloride (PVC) free food-grade TPU lining ensures water remains safe and taste-free. The multi-function, low-profile cap integrates a wide-mouth opening for quick refilling, a precision flow-control spout, and an extra-small shower fitting—perfect for hygiene in remote settings. With an adjustable TPU strap and integrated welded handle, this 10L reservoir can be securely hung, carried or lashed to vehicles or backpacks. Built tough but refined for usability, the Watercell X brings durability and flexibility to water storage wherever your adventure takes you.
