"The LIFA® Active Solen T-Shirt uses lightweight LIFA® Active fabric to pull moisture away from the skin during hard efforts on the trail or the water. UPF 50+ protection blocks sun on long days out, whether we're hiking, sailing, or logging trail miles. A crew neck and internal hanging loop round out a shirt built to move with the activity, not just cover it. What Our Gearhead® Experts Are Saying:""I wore this on a hot, exposed trail run and never felt that clammy stick-to-your-skin feeling. The fabric pulls sweat to the surface and dries fast enough that I stay comfortable mile after mile."""
