Pairing function and performance in a mid-weight and packable style, the Prime Vest is designed for layering on cool and damp days. Constructed from a highly breathable Polartec® Neoshell fabric featuring thermo-taped seams, it provides a waterproof and windproof experience. Featuring a 2-way YKK zipper, it's easy to access jersey pockets, increase airflow when the pace is hot or zip up to keep the elements out. Reflective print transfers on the side and back enhance visibility in low light conditions, and a small waterproof pouch pocket with a zipper offers safe storage.
