The Elements™ Jacket - NAVAIR is NAVAIR approved and designed specifically for Navy and Marine Corps Aviators. After being rigorously tested by troops worldwide, this system was crafted with fully flame-resistant 4-way stretch Massif® Battleshield X® softshell fabric featuring WINDSTOPPER® technology by GORE-TEX® LABS, a windproof, water resistant, breathable membrane for unmatched durability, and extreme comfort. Each garment was created from our end-users feedback for the best fit and functionality possible and is constructed with Dupont™ Kevlar® and Nomex® brand fiber - the first flame-resistant fiber selected for use in military uniforms.
