This video will show you how to set up the three harness mounting options - head harness, helmet harness, and O2 mask strap - for the Ops-Core Special Operations Tactical Respirator, or SOTR. A series of snaps, velcro, and connector clips help the user easily fit and adjust the SOTR based on their mission requirements. One of our helmet accessories, SOTR is a half-mask tactical respirator mask that filters 99.7% of airborne particulates. It is designed for integration with our other tactical gear, including NVGs, protective eyewear, communications headsets, and military helmets.
