Unfortunately, there are counterfeit and replica Combat Application Tourniquets (C-A-T), and SOF-Tactical Tourniquets, and possibly other brands of medical and tactical products available in the market. These products are not covered by CTOMS nor the authentic product manufacturer’s warranties. Because there are so many variations of the counterfeits, it is difficult to provide specific detection guidance. To avoid the risk of purchasing counterfeit products, we recommend that you purchase directly through ctomsinc.com. Please contact us to report suspected counterfeits in Canada.
