When you're on a multi-night expedition through the backcountry, everything from your camo to your cookware is deemed double duty. So save some space by transforming your Rambler Bottles with the new YETI Cup Cap. Not only is it compatible with the whole Rambler Bottle line, but it offers twice the functionality. The FatLid insulation keeps your coffee, tea or even whiskey at the perfect temperature, while the detachable cup twists off to turn your double-wall vacuum insulated bottle into a hot beverage dispenser and the cup into, well a cup- the perfect combination for a mid-adventure pit stop. Like all Ramblers, the 5 oz Cup Cap and the bottle are dishwasher safe and it also features No Sweat Design making condensation an inconvenience of the past.
