The Prime Vest pairs together function and performance in a mid-weight and packable style. Constructed from a highly breathable Polartec® Neoshell fabric featuring thermo taped seams, it provides a waterproof and windproof experience. The 2-way YKK zipper allows you to zip in either direction, zip up from the bottom for easy access to underlayer pockets, or for maximising airflow on those tough climbs while being able to easily and quickly rezip on the descent. The Prime Vest also features reflective print transfers for enhanced visibility and a small zippered pocket on the rear.
