Deep Space Neckgaitor is designed for comfort, warmth and versatility with the high tech deep space fabric. Trizar™, a NASA Certified Space Technology woven into every fiber of this garment before it is constructed. Trizar captures body heat inside the garment and re-radiates it back to the user, keeping you warmer. Trizar also diffuses moisture, moving perspiration out of the garment to keep you dry and comfortable. The Deep Space Neckgaitor delivers scent control through an exclusive combination of Polygiene Odor Crunch + Stays Fresh, offering the most comprehensive odor protection on the market. This combination tackles odors caused by bacteria coming off the body while simultaneously eliminating outside odors, such as campfire smoke, to help you go undetected. Wear it around your neck or pulled over your nose for the coldest days. The neckgaitor has full 4 way stretch to go over your head when maximum concealment is needed. Made multiple colors to match your full kit.
