The Gentoo full length onesie—now available in kid’s sizing (ages 6-14)—is cut in a super soft and stretchy fabric made from breathable, recycled Nylon that will keep your sweat in check. Our signature temperature stabilizing fabric is sustainably manufactured. Easy to put on and take off (see: buttons), with 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 with a kid-friendly, hook-and-loop entry. The Gentoo full length onesie can be worn under outerwear as a base layer or on it’s own. Perfect for bunny hills, black diamonds, hot chocolate breaks and everyday playtime!
