YHM's Sound Suppressor Covers with an industry leading suppressor cover retention system. Using our unique locking straps, your cover is secured to your suppressor ensuring it stays in place while shooting. Most other covers will loosen up over time and begin to slide off. When you are on target, the last thing you need is to look up at your cover. Our covers are made from only the highest quality materials. The base layer is flash rated to 3000°F and the middle material is rated to 1800°F. The outer shell is a durable 1000 Denier Cordura Nylon that is water resistant and stands up against fading, abrasion, rot, and mildew. We even chose a high quality fire resistant thread to ensure every aspect of the cover can stand up to the toughest environments.
