The Source Storm Valve Kit is the valve of choice on Source's winter-specific hydration systems as it is particularly resistant to Alpine conditions, but this isn't its only application. Some folks simply prefer the safe-as-houses security of a twist-lock valve, and the Storm is also great for kids who are in the habit of chewing the Helix valve to bits!
