Mountain Bike Short Sleeve Jersey – Men's

Built for riders who push hard and sweat harder, the Mountain Bike Short Sleeve Jersey is our top pick for warm-weather trail days. Smartwool's merino blend naturally regulates temperature and kills odor without chemical treatments, so you stay fresh on long efforts. Flatlock seams and an on-bike athletic fit keep chafing and restriction out of the equation.

• Merino wool blend construction regulates temperature naturally and resists odor — no synthetic treatments needed
• Moisture-wicking, breathable knit moves sweat off skin fast, critical during humid Southern trail days
• Athletic fit is cut for the forward riding position without locking up your movement on technical climbs or descents
• Flatlock seam construction eliminates hot spots and chafe on long rides where every contact point matters
• Lightweight enough to wear solo on warm days, versatile enough to layer under a shell when the weather shifts
