The Men's Sonic Zip T-Shirt from Montane has flat-locked seams to lower the potential for friction, as well as reflective detailing to help you stay visible when out after dark. A low rise collar is designed for use with a pack, while the YKK quarter-zip provides ventilation. The Sonic is an ideal choice for anything from a summer walk to a tough run.
Apex-Dry is a lightweight, anti-static high performance baselayer fabric which wicks away moisture, dries fast and protects the skin from the sun with a UPF of 50+. It's teamed with the Apex-Dry underarm mesh to create great air permeability and moisture wicking properties.
