Why our Vert Junkies® love this

Cold air. Hot engine. This midweight half-zip keeps the throttle open without cooking you out. Fine 17.5-micron merino blended with polyester for stronger wear and faster dry-down.

Key Features

  • Midweight 270 gsm knit for four-season layering

  • 79% merino wool / 21% polyester blend: wool feel, added durability

  • Half-zip vent to dump heat on the climb

  • Mock-neck collar for seal-up warmth when the wind spikes

  • Moisture-wicking + quick-dry performance for high-output days

  • Odor resistance from merino’s natural properties

  • Thumb loops to lock sleeves in place under gloves and shells

  • Reflective detail for low-light visibility

  • Close-to-body fit + longer back hem for clean layering coverage

Recommended Use

Run it next-to-skin for ski days, cold runs, and long hikes where sweat is guaranteed. Zip up for ridge gusts, zip down when the pace turns savage. Add a shell and you’ve got a hard-charging system.

Bottom Line

Midweight merino blend. Half-zip control. Zero excuses.
