These products are generally referred to as wraps. A wrap can look very stylish, and can also serve the purpose of appropriate camouflage. They are primarily used for reducing heat mirage for long-range/sniper situations where the magnification of the optics can be impaired with mirage. While these products serve a purpose and are tolerant to extreme temperatures, they do break down under intense heat exposure and while they are designed to handle high-heat thresholds, they increase the temperature of the suppressors, and do little to protect a shooter from burns with accidental contact with the suppressor cover. The typical cost of this suppressor is 3-4 times more expensive than the KoolHand silicone-based suppressor cover. These products may consist of materials such as Kevlar, Nomex, Cordura, Shock Cord and possibly silicone adhesives, sometimes in a 2-part assembly.
