Professional bodybuilder Stan Efferding is the entrepreneur behind The Kooler, a one-gallon beverage cooler designed to keep pre workout, during workout and post workout drinks separate but cooled in one big container. Efferding is pitching his product with a lively demonstration – flipping over a 800lb tire and pressing 200lb dumbbells – on Shark Tank (February 3).
The Kooler, the original, comes with two shakers and is sold for $32.95. The Kooler 2.0 version comes with a key chain holder, pill pockets, and easy pull-off cap, and will be available for $40 in May 2017. Shark Tank airs Fridays at 9pm on ABC.
