Smartwool Mountain Bike Short-Sleeve Jersey

What Our Gearhead® Experts Are Saying:

"This jersey keeps me cool and comfortable on long rides. The Merino blend wicks away sweat, the mesh zones boost airflow, and the drop-tail hem provides extra coverage when I’m charging downhill. It’s the perfect mix of comfort, breathability, and performance."

On the trail, we want our focus on the ride—not our gear. The Mountain Bike Short-Sleeve Jersey is designed to keep us cool, dry, and comfortable through every climb and descent. Made from a lightweight Merino blend, it naturally regulates temperature, wicks moisture, and resists odors, so we stay fresh from the first pedal stroke to the last.

Strategically placed mesh panels enhance breathability in high-heat areas, while the drop-tail hem provides extra coverage for aggressive riding positions. The relaxed yet performance-ready fit allows for full mobility, ensuring we stay comfortable no matter how technical the terrain gets.
