Watercell X
Watercell X
400D Recycled Nylon · TPU Film · RF-Welded · 4 Sizes · 170–335 g · BPA/PVC-Free · Converts to Shower

The Watercell X is the go-to solution for storing, transporting, and dispensing water on any adventure — camping, overlanding, paddle touring, or basecamp showers. Its wide-mouth design makes filling, draining, and drying fast and easy, while the low-profile 63 mm multifunction cap provides one-handed variable flow control. Built from bluesign-approved certified recycled 400D nylon with RF-welded TPU film construction that's BPA, PVC, and non-PFAS, it converts in seconds to a backcountry shower with the included fitting that stores on the carry strap. Adjustable TPU strap and welded lash points let you carry it, hang it, or lash it to a pack or vehicle on the move.

Wide-Mouth Design
Wide-mouth opening makes filling from taps and streams, draining, and drying between trips fast and easy — no narrow-neck fumbling or special brushes required.
63 mm Multifunction Cap
Low-profile 63 mm cap provides variable flow control and is easy to operate with one hand — pour, seal, or dispense without putting the cell down.
Converts to Backcountry Shower
Easily converts to a backcountry shower with the included fitting — stores on the carry strap when not in use so it's always available.
Certified Recycled 400D Nylon
Made from durable, flexible, bluesign APPROVED certified recycled 400D nylon — tougher than standard TPU-only bladders and built for repeated backcountry use.
3D-Baffled RF-Welded TPU
Sturdy 3D-baffled, RF-welded TPU construction is stackable, leakproof, and free of BPA, PVC, and PFAS chemicals for safe drinking water storage.
Adjustable TPU Strap
Adjustable TPU strap lets you carry the cell by hand, over the shoulder, or hang it from a tree branch in camp for hands-free gravity filtering or showering.
Welded Lash Points
Welded lash points provide versatile options for securing the cell to a pack, raft, vehicle interior, or exterior cargo net on the move.
Freezable
Can be frozen with water inside (leave room for ice expansion) for use as an ice block in a cooler — welds, laminates, and cap handle cold temperatures without damage.
Four Sizes
4L, 6L, 10L, and 20L sizes cover everything from a day-hike drinking reservoir to a multi-day camp water hauler and group shower.
1/4 in NPT Spigot Thread
Internal spigot/showerhead connection thread is 1/4 in NPT — compatible with CPC 1/4 in NPT to quick-connect fittings for hose and accessory setups.

Wash with warm water and dish soap, rinse thoroughly, and hang upside down to dry completely between uses — wide-mouth design makes this fast and easy.

Do NOT use boiling water for cleaning — high temperatures can damage the welds, laminates, and cap threads.

To remove juice, wine, or other stubborn residue, use effervescent peroxide tablets designed for hydration bladders.

Do not machine wash or tumble dry — agitation and heat damage the RF-welded TPU construction and stress the welded lash points.

Avoid prolonged direct sunlight or UV exposure when storing; the TPU film and 400D nylon will degrade faster in direct sunlight.

Inspect the RF welds, TPU film, and cap threads before each trip; if a weld starts lifting, the film develops a haze, or the cap threads seep, retire the cell from drinking-water use.
