The classic canteen from Corkcicle will help keep you on the go through whatever your day may bring! Your beverage will stay cold for 25+ hours, or hot for 12 hours. The canteen is vacuum sealed, triple insulated, BPA free and made from stainless steel. It is designed with easy-grip flat sides and a non slip bottom. The mouth is large enough for ice cubes. We suggest pairing the canteen with the Canteen Straw Lid, which allows for even more convenience, especially if you are using the bottle at the gym or in the car!
