Technical enough for the trail and comfortable enough for everywhere else, this versatile, soft-on-skin merino blend polo crosses comfortably between mountain life’s many modes.

Combining performance fabric with easy comfort, this long-sleeved work-to-play shirt readily holds its place in the weekend or weekday lineup. Just the right weight for cool-to-warm transitions, the secret to its versatility is our signature PeakWool™ fabric blend, a proprietary textile that interweaves premium merino wool with Tencel, nylon and elastane for a fabric that is soft, moisture-wicking and breathable.
