Yeti wants to give you a hand, or at least a Handle, when it comes to securely hauling your Rambler Tumbler. The Rambler Tumbler Handles offer an alternative way to hold your 20 oz. and 30 oz. Tumblers to optimize portability. The Handleís rubber grip provides an easy fit for your Rambler and its polypropylene construction means your Handle will handle bumps and thumps just fine. Because itís not just a cup handle Ė itís a YETI.
