A 125 gsm Nuyarn merino base layer built to sit under everything else you wear.
The body-contouring fit keeps the fabric in contact with your skin, which is what allows a base layer to move moisture instead of trapping it. Nuyarn spins merino around a nylon core without the tight twist of conventional yarn, so the fibers stay lofted. That loft holds air for warmth at a low weight and releases moisture faster than conventionally spun merino of the same gsm.
At 125 gsm it layers nicely under a cycling jersey, ski gear, or a sweatshirt without adding bulk at the shoulders or waist.
Peat is a dark, desaturated brown with a green undertone. It stays neutral under earth-toned and mid-tone outer layers and shows less grime than a light color over a long season.
Made in USA.
Our sizing is gender neutral or unisex. Please use our size chart to compare your measurements and select the corresponding size. If you're in-between sizes we recommend sizing up.
Our base layers are cut in a body-contouring fit, slimmer than our performance tees. A base layer needs to stay in contact with your skin to move moisture, so it should feel close without restricting movement. If you prefer a looser fit, or plan to wear it as a standalone piece, we recommend sizing up. Nuyarn merino has exceptional stretch and rebound and fits a wide range of body types.
The sleeve length and overall length run a bit longer than average to allow for comfortable wear on a bike and to keep the layer tucked under a jersey or shell. The rear hem is slightly curved and longer than the front for additional coverage when you are in a riding position.
