The Watercell ST is your streamlined water storage solution for lightweight adventures. Minimalist, strong and pliable, its compact 3D shape and internal baffle design makes it manageable and easy to fill, stow, stack and drain.
It's constructed with RF-welded seams for ultimate strength and reliability, as well as food-grade TPU which is also BPA and PVC-free. Strategically positioned water-resistant grab-handles offer carry and lashing options, while the screw-top standard wide-mouth opening and low-profile fill handle make filling effortless.
Fill lines printed on the rear of the Watercell show the approximate volume. The 63mm thread of the fill-opening is compatible with many water filters / purification systems, and with standard hard-plastic drinking bottle caps.
These products are all Bisphenol-a (BPA) free, which means you can have peace of mind while eating and drinking from these products.
This product is free of any Polyvinyl Chloride (PVC). This means that the production process is significantly more environmentally friendly, and the disposal of the product at the end of its life will also not burden the environment. With advances in modern polymers, it also means there's no reduction in performance.

Frequently Asked questions
Can it be used with the Watercell X shower attachment?
No, if you want to use that shower attachment, you will need to purchase the coordinating Watercell X.
Can it be cleaned with bleach?
We don't recommend using bleach in the Watercell. Instead, try taste-free peroxide cleaning tablets that are just as effective and don't leave an aftertaste.
Can it hold liquids other than water?
Yes, you can use other liquids in the Watercell, but only if it's cleaned correctly and thoroughly afterwards. We recommend using peroxide cleaning tablets for an effective clean without the aftertaste.
Will it leave a residual taste in the drinking water?
The TPU film is made to leave the least amount of residual taste. However, no soft-sided water container (regardless of brand) is completely taste-neutral, except the Mylar bladder of the Pack Tap.
