Yeti Rambler 30 oz.

YETI Ramblers are advanced personal drink coolers made from 18/8 stainless steel with double-wall vacuum insulation. Rambler Tumblers will keep your soda or mixed drinks cold twice as long as plastic cups, and make an excellent YETI coffee mug. The Rambler Colster locks in the cold of cans and bottles using a heat-mocking ThermoLock™ Gasket.
