The GU flask is designed to be able to cleanly and conveniently stash extra fluids within a pocket when taking on lengthy and strenuous activities. Developed in partnership with their neighbors at Hydrapak, this soft flask features a high flow valve that easily dispenses the contents when needed, and this valve can be shut off to keep pockets and bags clean when stashing the flask away. A large opening makes dropping powders, tablets, and water into the flask a breeze, and the 500ml size delivers the ideal fluid volume to prepare one serving of most energy and hydration drink mixes. Last but not least, the translucent material enables quick monitoring of fluid levels during consumption and makes it is very easy to know when the flask has been properly cleaned out after each use.
