The KINTO WORKOUT BOTTLE is designed to fit your active lifestyle. Those familiar with the KINTO TRAVEL TUMBLER, will appreciate the simple 3-piece construction - making it a cinch to drink out of and very easy to clean or add ice to cool down your drink. The bottle is made of BPA-free plastic that is light, durable, and smooth to the touch (and is a delight to drink from!). A silicone strap makes carrying easy and allows you to hook the bottle on to your backpack or yoga bag.
