This lightweight, collapsible flask features our classic one-piece silicone bite valve for rapid hydration on race day, and packs down easily once its empty. We designed the Quick Stow to fit easily in the front compartments of all of our running vests. Once its empty, it folds down small enough to fit in your pocket.

• Bite valve self-seals after each drink, eliminating annoying drips
• Empty flask collapses and folds ultra-compact to fit in most pockets
• Cap is top-rack dishwasher safe
• Volume indicators in ounces and milliliters for tracking hydration and adding electrolytes
• Hang flask upside down for easy drainage and drying
