About ThermoFlask Deals, Promo Codes & Cash Back

ThermoFlask began in 2012 when we built a bottle that inspired adventurers to fill their flask, feel their best, and get going. We innovated a lid system to keep the cold in longer, make ice load easy, and never leak. Shop with Active Junky to earn Cash Back today!
