The YETI Rambler Bottle is the perfect for every day, all day. Rambler Bottles come with a new Chug Cap. With a quick twist, the TripleHaul™ handle comes off, exposing the shatter-resistant, dishwasher safe spout. The spout is also removable if you prefer just the wide mouth. All bottles are equipped with double-wall vacuum insulation, and are made of durable 18/8 stainless steel.
