The New HSS-Cowbell Carabiner Cover (Patent Pending) from HSS is a sound dampening, weather-guard shield designed to go over your carabiner. The soft, silicone HSS-Cowbell serves as an effective sound dampener, eliminating nearly all of the noise generated by your carabiner's contact with metallic items such as your steps or stand. The HSS-Cowbell also helps to weather-guard your LIFELINE's Recon carabiners. Because it's made of silicone, the HSS-Cowbell will last for years in exposed conditions. Note: The HSS-Cowbell comes standard with the new REFLECTIVE LIFELINE.
