Sea to Summit's Watercell ST is your streamlined water storage solution for lightweight adventures.


Minimalist, strong and pliable, the Watercell ST’s compact 3D shape and internal baffle design makes it manageable and easy to fill, stow, stack and drain.


Engineered using RF welded seams for ultimate strength and reliability, it’s made from abrasion resistant semi-translucent TPU for flexibility and durability. The food-grade TPU is also BPA, PVC and taste-free.


The 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.


The upright cell structure provides efficient use of the internal volume and allows the Watercell ST to drain completely for drying at the end of a trip.
