Wherever your adventure takes you, a long-sleeve is the ideal companion for comfort and warmth, from cold morning rides on the trail or layering up for a mid-winter run. Crafted from Nuyarn® merino wool, our long-sleeve baselayers are designed to wick away moisture, stay fresh and last season after season thanks to the innovative weave of the fabric. Pair with our merino wool leggings to benefit from the full ARTILECT baselayer system.
Boulder
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.
