Stash it in your hiking pack, bottle pouch, or even in the palm of your hand. This lightweight, collapsible flask features our classic one-piece silicone bite valve for rapid hydration on hunt day and packs down easily once it's empty. We designed the Quick Stow to fit easily in all of our hunting backpacks. Once it's empty, it folds down small enough to fit in your pocket. The Quick Stow conveniently holds 500 ml (17 oz) of water and features the Hydrate or Die logo.
