The YETI Rambler Bottle Chug Cap makes it easier to sip and drink while on the move. The TripleHaul™ cap provides a 100% leakproof, insulated, airtight lock but also opens with a quick twist of the handle to reveal a classic clear spout ideal for quick gulps. Like the rest of the Rambler accessory family, it's shatter-resistant and safe to throw in the dishwasher.
