There's nothing like some freezing water to refresh yourself while you're running or biking under a hot sun, and the Camelbak Podium Big Chill Water Bottle makes sure your water stays cold for a long time. Its BPA-free TruTaste polypropylene material is safer to drink out of than polycarbonate plastics and it won't distort your water's taste, and HydroGuard insulation keeps your beverage chilled twice as long as regular sports bottles. The Jet Valve cap is spill-proof and self-sealing so you can squeeze some deliciousness down your gullet quickly and get back to what you were doing.
