The Gruv-X YETI® "Rambler® "18 oz. tumbler is a necessary addition to your gigs and rehearsals. This tough bottle is double-wall vacuum insulated to keep your water cold until the last sip, dishwasher safe for easy cleaning, and comes standard with the Chug Cap. With a quick twist, the TripleHaul™ handle comes off, exposing our shatter-resistant, dishwasher safe spout that allows for controlled gulps on the gig!. When it’s time for a wash or refill, remove the entire cap to expose the bottle’s wide mouth. Separate your Rambler from all others with the DuraCoat Black, over stainless with the full GRUV-X logo finish. **The Chug Cap is not intended for use with carbonated, perishable, or hot beverages.
