The Contender Bicycles Polar Insulated Bottle features a triple layer of insulation in the wall to keep beverages cold up to twice as long as other bottles. Lightweight construction and a breakthrough valve design enable easy refueling during rides both long and hard. Equipped with the new Breakaway Surge Valve, the Contender Bicycles Polar Insulated Bottle has maximized flow, a spill-proof when open and leak-proof when closed design. The soft bottle is easy for squeezing to make hydration on the go a breeze. Made from 100% BPA free materials, the Contender Bicycles Insulated Bottle features the logo of your favorite bike shop, of course. One thing you&';ll love is the removable cap valve which makes washing the bottle easy and prevents nasty gunk buildup.
