Matek is reinventing performance layers and doing it with incredible style that makes us excited to jump into our long underwear.

What's the Gentoo? It's a genius, game-changing cold weather essential. As a full length one piece designed with comfort and performance in mind, it can be worn by itself or under your outerwear as a base layer.  

Matek's 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.

There are many clever details that have us grinning. Front button closures make layering a swift process, while the easy-access butt-flap —a nod to the union suit of yesteryear— has a hook-and-loop entry that will help you conveniently go to the bathroom without getting naked. A real win in women's onesie design. 

Built with skiing and snowboarding in mind, thin mesh at the calves keep your socks in place and ensure there’s less bulk cramming up your boots. 

Perfect under layers for a freezing day in Whistler or on its own for a spring day in Tahoe. Apres ski chic, slope ready and also perfect under jeans off the mountain.
