The Quick Stow flasks fuse technology from the Crux reservoirs and Podium bottle line. Stash it in your running vest, belt, or even in the palm of your hand. This lightweight, collapsible flask features our classic one-piece silicone bite valve for rapid hydration on race day, and packs down easily once it’s empty. CamelBak designed the Quick Stow to fit easily in the front compartments of all of our running vests. Once it’s empty, it folds down small enough to fit in your pocket.
