The Quick Stow Flask 12oz by Camelbak will change your perception of trail running. No more sloshing sounds in your bottles. The Quick Stow Flask 12oz compresses as you drink, preventing any water from sloshing inside. Not only is there no noise, but it also takes up less space. Not a drop wasted. To get water into your mouth, simply pinch the valve with your teeth. The Quick Stow Flask 12oz features our classic one-piece silicone bite valve for quick hydration on race day and can be easily stored once empty. Designed to fit easily into the front compartments of all our running vests, the Quick Stow Flask 12oz is ultra-convenient during high-intensity efforts.
