From long trail runs to recovery treks, the Smartwool Active Long-Sleeve Tech T-Shirt keeps our microclimate feeling just right. As it pulls away sweat and lets the breeze blow through, the silky soft merino-lyocell blend feels cooling against our skin. The low-bulk seams ensure chafe doesn't slow us down, and the reflective details light up under streetlights and in headlights to keep us seen on the final strides home.
