Osprey’s insulation system is a bladder tube, thankfully already threaded into a foam padded sleeve that extends right over the bite valve and is sealed with a zip. The material is reflective so should keep water cool in hot temperatures as well as preventing freezing in winter. In my experience it still froze on one very cold day on the Cairngorm plateau.
