The opinion of Aventure Nordique

The Watercell ST from Sea To Summit is a water tank that is soft, flexible and strong at the same time. This water pocket is a compact and lightweight storage solution. It is practical and easy to use thanks to its 3D shape and internal deflector. The Watercell ST has a wide opening, making it easy to fill, clean and drain. The semi-translucent TPU material allows the remaining contents to be viewed. This TPU is food grade, BPA free, PVC free and tasteless.

Technically, this flask has welded seams and 2 strong handles for easy carrying.

The large screw opening is compatible with water filtration systems with a standard thread.
