Shell Layer: Designed to be worn with base and insulative levels in transitional environments to provide wind and sand protection.
The Wind Jacket is designed to act as a low volume shell layer that optimizes the moisture wicking properties of other GEN III insulative and next-to-skin layers. It is also designed to be worn under body armor. Constructed from stretchable nylon with a water resistant finish, this full-zippered jacket provides wind and sand protection with low weight and bulk.
