On Climate Shirt

Description

A mid-layer that offers a lightweight warmth for you to snuggle into on cold winter runs, the On Climate Shirt in Black lets you push hard thanks to its multi-dimensional surface structure that gives you superior wicking and moisture management.
The On Climate Shirt features darts in the elbow and back so that it can curve and contour your body, and a quarter zip entry for easy on off, and a variable ventilation.

A thumbhole locks the sleeves in place when worn under a shell, and reflective

details offer improved visibility in low light conditions. A zipped side pocket holds essentials securely.
