The 22QB Airsoft guys talk about the Lindnerhof Curv Belt that they recommend for its top quality design. Lindnerhof’s Curv Belts are made of a polypropylene base and a 500d layer of specially coated CORDURA, inspired by the automotive industry. They are designed to meet tactical-use requirements, including ultra-low weight, high impact strength, flexibility, and resistance to fracturing even in very cold temperatures.
