After a few short warm-up exercises, you lace up your running shoes, pull on your favorite running top, and get ready to run faster – and maybe a little farther too. This mid-layer, made sustainably from recycled fibers, is specifically designed for training in cold weather, providing active warmth and unrestricted freedom of movement. A half-length zipper allows you to individually regulate your body climate, effectively ventilating or insulating as needed.

The perfect mid-layer for quick winter runs or intense ascents.
