Merino Short-Sleeve Base Layer - Men's

What Our Gearhead® Experts Are Saying:

"I've run this under my jersey on long summer training days, and it handles moisture better than anything synthetic I've tried. The merino wool keeps odor in check even after back-to-back rides. It layers clean under a jersey without adding heat or bulk."

We built the Merino Short-Sleeve Base Layer for riders who need warm weather performance without sacrificing comfort. A 74% merino wool blend forms the base, managing moisture and odor across long, hot efforts, while 16% nylon adds durability and structure to a fabric that stays soft against the skin. The remaining 10% elastane keeps the fit close, which matters most under a jersey where loose fabric only adds drag and discomfort.

That close, second skin fit keeps the base layer compatible with the full range of summer jerseys in rotation, sitting flat under thin fabrics without bunching at the shoulders or waist. Merino's natural moisture management and odor resistance do the rest, making this the layer riders reach for on long days in the heat or back-to-back training blocks where fresh gear matters.
