This rugged canteen is made of a heavy weight cotton canvas with a BPA free liner. It holds up to 750 ml. of wine. Clip it to your backpack, belt or bike with its aluminum carabiner. Expels oxygen to preserve the flavor and quality of fine wine. It rolls up when empty.
So perfect for day tripping, camping, backpacking, biking, beachcombing, and just plain relaxing. Tuck it away until your next adventure!
