Performance Wool Long-Sleeve Top - Men's

What Our Gearhead® Experts Are Saying:

"I’ve worn the Performance Wool Long-Sleeve for both ski days and cool-weather runs, and it’s an absolute go-to. The merino-Tencel blend keeps me warm without overheating, and the mesh ventilation zones really make a difference during high-intensity efforts. It’s light, slim, and layers perfectly under a shell."

When we need a base layer that works as hard as we do, the Performance Wool Long-Sleeve Top steps up. Made from a 50/50 blend of merino wool and Tencel, it naturally regulates temperature, wicks moisture, and keeps us comfortable through long training sessions—whether we’re gliding over snowy trails or pounding the pavement on crisp mornings.

Mesh panels at the back and underarms boost airflow when the pace picks up, while flatlock seams eliminate chafing during repetitive movement. The slim fit layers effortlessly under midlayers or jackets, and the soft merino-Tencel fabric feels great against the skin. Built for high-performance training in all conditions, this long sleeve keeps us ready for every workout.
