Don’t fill Drink Tank with ordinary swill: such a chalice merits the finest of Colorado microbrews. Summer ales, winter stouts and everything in between stay cold and frothy inside the stainless steel, double-walled vacuum growler. While excessive for multi-night treks, the Drink Tank supplied three backpacking testers with a couple IPAs each on an overnight in Colorado’s alpine dales. “There’s nothing better than a cold beer miles away from roads, let alone a brewery,” said one wistful tester upon his return. The Drink Tank shines as a novel way to enjoy a carbonated beverage at the park or on the trail. Convert your Drink Tank growler into a portable keg with the Keg Cap; you’ll marvel at the still-frothy draught a full 24-hours after topping it off at your local brewery.
