CamelBak Quick Stow Chill Flask

This LightWeight, collapsible flask keeps your water cold twice as long, without the extra Weight and bulk of traditional insulated bottles. The Quick Stow Chill fits snugly in the front pockets of all CamelBak running vests, and collapses for easy storage once it's empty. The extra-Wide mouth also makes it easy to refill on the fly, especially if you're adding ice or drink mixes. CamelBak's classic one-piece silicone bite valve offers a durable user friendly drinking interface.
