Our short sleeve t-shirts can be used for a wide range of activities, from summer hikes to late season skiing and boarding. Featuring Nuyarn® merino wool, our t-shirts keep you cool and dry all day long thanks to the natural moisture-wicking properties, layer with a warmer jacket for those colder adventures or pair with a lightweight shell for rainy days.
Named after our home in Colorado, our Boulder collection is the first of our A/SYS-1 range and features a lightweight 125 GSM Nuyarn® fabric for shoulder seasons or those who prefer a lighter baselayer for those higher output activities. Where the Rocky Mountains meet the Great Plains, you’ll find Boulder Valley, a hub for intrepid explorers searching for a deeper connection to the outdoors.
