Watercell ST

The Sea to Summit Watercell ST is your streamlined reservoir water bag 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. For ultimate water storage, the Watercell ST features RF welded seams and abrasion-resistant semi-translucent TPU providing ultimate flexibility and durability. The food-grade TPU is also BPA, PVC and taste-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 fill volume. 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. The 63mm thread of the fill-opening is compatible with many water filters / purification systems, and with standard hard-plastic drinking bottle caps.
