The Gentoo is a full length one piece which can be worn by itself or under your outerwear as a base layer. Our signature temperature stabilizing fabric is sustainably manufactured. Made out of super soft and stretchy recycled Nylon fabric that will keep your stank and sweat in check. Easy to put on and take off with front button closures, the Gentoo full length onesie is designed with comfort and performance in mind. Thin mesh at the calves that’ll keep your socks in place and ensure there’s less bulk cramming up your boots. Finished with an easy-access butt-flap—a nod to the union suit of yesteryear, except streamlined with a hook-and-loop entry. Perfect under layers for a freezing day in Whistler or on its own for a spring day in Mt Bachelor. Great to go right into Apres-ski fun in or wear with jeans out to dinner. *this item is final sale and cannot be exchanged or returned.
