Keep cool this Stampede. The Wailea double-wall, vacuum sealed 4-in-1 can insulator is made of 18/8 stainless steel and food-grade silicone, with a Calgary Stampede logo embossed on the side. It's designed to fit a 355 ml regular short can, a 355 ml slim can, and 341 ml longneck bottle. The Wailea is engineered to ensure your favourite beer, pop, hard seltzer and energy drink ice cold for up to four hours. A KAILANI-only feature is our Sure-Grip finger channels on each side of the insulator for comfort and better grip - no one wants to drop their drink!
