The guys from American MilSim give you a quick overview on the Crye Precision MRB.
Our MRB(Modular Rigger’s Belt) is a single, lightweight belt system that carries your gear and holds up your pants. Features our new LoopLock™ inner belt layer that passes through pants belt loops, keeping the MRB oriented and stable.
