Why our Vert Junkies® love this

Cold rides. Zero mercy. This is a heavyweight synthetic thermal baselayer built to trap heat, block wind, and stay glued to your skin when temps dive. Brushed fleece inside. Stretch knit outside. Built for winter miles, not café stops.

Key Features

  • Heavyweight fleece interior locks heat fast and holds it

  • Synthetic knit (85% polyester / 15% spandex) for stretch, durability, fast dry

  • Wind-resistant outer face cuts chill under a shell or jersey

  • Anti-pilling, anti-shrink, anti-wrinkle—ride it hard, wash it often

  • Next-to-skin athletic fit for efficient moisture transfer

  • Full-length sleeves + crew neck = full coverage, no gaps

  • Flat, clean stitching reduces rub under packs or armor

  • Zipperless pull-on design—simple, fast, nothing to fail

Recommended Use

Built for cold-weather cycling, MTB, road training, commuting, and moto layers from late fall through deep winter. Best for low to mixed output days when wind and cold are the enemy and warmth matters more than max airflow. Size runs smaller than US standard—size up if between.

Bottom Line

Heat in. Cold out. Ride anyway.
