The Sea to Summit Watercell ST is a flexible and durable backpacking water reservoir.

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 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. 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 Watercell ST 4L ensures efficient use of the internal volume of four liters. When not in use, the Watercell ST 4L weighs only 120 grams and can be folded very compactly so that it does not take up unnecessary space among the equipment (a significant advantage over water bottles and flasks). The Sea to Summit Watercell ST is especially suitable for backpacking, cycling or kayaking and wild camping in dry and remote areas where access to drinking, cooking and cleaning water is limited.
