Why our Vert Junkies® love this

Cold starts. Long sits. Hard climbs. These 250 GSM merino bottoms keep heat in play, dump sweat before it turns icy, and stay wearable when the miles stack up.

Key Features

  • Midweight warmth (250 GSM): built for real winter layering without the bulk

  • 100% merino wool knit: natural loft + steady heat retention

  • Moisture-moving performance: pulls sweat off skin to help prevent chill-down

  • Odor resistance: merino fights stink on multi-day pushes

  • Next-to-skin soft feel: smooth fiber hand, no scratchy drama

  • Stretch-ready cut: moves clean through steps, squats, and sidehills

  • Cuffed ankles: stays locked under socks and boots

Recommended Use

Run these under shells for ski days, late-season hikes, cold-weather camps, and long hours in the field. Best when temps are low and your output swings between moving fast and standing still.

Bottom Line

Midweight merino heat you can live in, when the forecast turns mean.
