A few months ago, a new brand of “technical performance intimates” (otherwise known as long underwear) called Matek launched. Pieces include a surprisingly flattering button-down one-piece long john called a Gentoo, a sweat-wicking turtleneck leotard and legging set, and a weirdly charming unisex fleece turtleneck bib with arm holes called a Dik-Dik.

One need only take a glimpse at the brand’s Instagram feed of vintage ski snaps to understand that the sport’s rich history is a key player in Stern’s designs. However, her ultimate driving inspiration “is how far the fabrics have come,” she explains, pointing out her four-way stretch jersey, which is equipped with sweat-wicking, odor-protecting, and quick-drying materials and made from recycled nylon.

By incorporating mesh on the calves, Matek ensures you won’t experience sock slide or bunching underneath your boots for all-day comfort. Last but not least is the easy-access butt flap, making bathroom breaks a breeze. Pair the Gentoo with the Serval bra and you’ve got yourself a killer combination for slaying the slopes.

As a gift to myself, I’m going to buy a bunch of Matek’s Serval sports bras. They are incredibly well-made with double mesh, hold in my ladies, and double as nursing bras because there is a latch on each strap. I have searched high and low for a great nursing bra that actually holds up my size G breasts, and Matek has been my savior.
