The Insta-Chill Can Cooler uses active cooling gel technology to chill any room temperature drink in 10 minutes flat. Just chill the Insta-Chill in the freezer for 1 hour and wrap around your favorite 12 oz. can, securing the cooler with a slim velcro strip. The flexible neoprene design makes this can cooler comfortable in the hand, and lets you unfold it into a flat cold pack for coolers and more.
