Why our Vert Junkies® love this

Cold wind on the descent. Sweat on the climb. This is the layer that keeps the engine hot without turning you into a sauna. Next-to-skin stretch, brushed fleece bite on the inside, clean face on the outside—built to charge through winter miles.

Key Features

  • Midweight thermal punch: brushed fleece interior traps heat fast for cold starts and long descents

  • Synthetic sweat management: 85% polyester / 15% spandex—quick-drying feel with serious snap-back stretch

  • Next-to-skin fit: tight/athletic cut for clean layering under a jersey, softshell, or shell

  • Crew neck build: smooth neckline seam for low-bulk layering under collars and straps

  • Durability where it counts: double-stitched hem for a firm, ride-after-ride finish

  • Minimalist solid design: black or white, no loud nonsense—just function

Recommended Use

Road tempo in the gray. Gravel grind in the wind tunnel. MTB laps when the air is sharp and you’re chasing that flow state. Dial it in for ~5–10°C rides depending on effort and layering.

Bottom Line

Lock heat. Dump sweat. Stay lit when the weather tries to shut it down.
