Camelbak’s Podium Ice Bottle keeps liquids cool for four times as long as normal bottles. This is made possible by using an inner aerogel layer that is extremely lightweight while providing incredible insulating properties. Features a wide mouth top for easy filling and the silicone JetValve nozzle automatically opens when the bottle is squeezed and closes on its own so no more fussing and spilling like with traditional valves. Made from Trutaste polypropylene with Hydroguard for a clean fresh taste every time.
