"The Helly Hansen Trail Long-Sleeve T-Shirt manages moisture and moves with a 4-way stretch built for pushing hard on the trail, whether that's a long run or a fast-paced hike. Offset and flatlock seams cut down on chafing over distance, while raglan sleeves keep the shoulders free through every stride. Reflective details on the front and back add visibility when the trail runs into low light. What Our Gearhead® Experts Are Saying:""I wore this on a hot, sweaty trail run and never felt the fabric cling or the seams rub, even past the point where I usually start chafing. It stayed dry against my skin the whole way back down."""
