How do thermal shirts work?
These form fitting high-performance layers are sweat-wicking on the inside and insulating on the outside. Go the extra mile during outdoor runs in cozy long sleeves. Soft and warm with four-way stretch, these moisture-wicking shirts are great for running. The fabric dries quickly and regulates temperature to help keep you warm even when wet. Not just for running, these long sleeve thermals are great for outdoor activities. Skip the chafe when moving around in shirts with seamless construction. Added bonus: many of our long sleeves have thumbholes that keep the sleeves down and chills out.
