Engineered for a lifetime, these mobile cold storage units are the toughest coolers made—they're even certified bear-resistant by the IGBC! With reinforced corners and thick walls, they insulate better for longer ice retention (up to 10 days) while protecting better against impacts. There's also stainless steel hardware and built-in UV resistance, adding additional layers of muscle which no other coolers can measure up to. Lifetime guarantee. Made in USA.
