Smartwool Men's Active Ultralite Short Sleeve

Smartwool Men's Active Ultralite Short Sleeve

A lightweight merino-Lyocell blend tee built for active use where breathability, odor resistance, and temperature regulation matter more than durability alone. Noticeably lighter than a standard merino tee without giving up the performance benefits.

Highlights

• 53/47 merino wool and TENCEL Lyocell blend - The Lyocell lightens the fabric and adds moisture management on top of what merino already does well. The result is a tee that breathes and wicks better in high-output conditions than a straight merino shirt.
• Temperature regulating and odor resistant - Merino's natural properties keep you from overheating on the climb and smelling wrecked at the trailhead. Multi-day trip friendly without the weight of a heavier merino fabric.
• Athletic body-skimming fit - Cut close enough to move with you without restricting. Stays out of the way during high-output activity and doesn't bunch under a pack hipbelt or harness.
• Offset shoulder and side seams - Seams are positioned away from high-friction zones to reduce hotspots and chafing during extended wear or under a loaded pack. A detail that matters on longer days.
• Reflective elements - Low-light visibility for early morning or evening runs and rides. Subtle enough to not affect the look of the shirt during the day.
• ZQ-certified merino wool - Sourced from farms that meet standards for animal welfare, environmental sustainability, and fiber quality. Worth knowing if responsible sourcing factors into your gear decisions.

Best For

Runners, hikers, and gym-goers who want a lightweight, odor-resistant performance tee that handles high-output activity and multi-day use without feeling heavy or holding onto sweat
