BCA was the first to pioneer the concept of freezeproof winter hydration. Then they made it more convenient with the Nalgene-compatible hydration system. In 2007-08, they've broken new ground by adding Outlast® temperature regulation technology.
The new Stash sleeves are insulated with Outlast® phase change material, which stores heat when it's produced and releases it when the temperature drops. With the Outlast® sleeve, your hose and bite valve now retain heat longer during cold lift rides or when you remove your pack.
