The Micro Grip Belt Liner turns any 1.75" rigger belt or 2" duty belt with loop inner Velcro® into a padded belt. Just take outer belt off of inner belt, apply liner, adjust the buckle and wear the same belt over layers securely and quickly. Sizes are determined by the length of loop Velcro® on HSG belts, but will also match up with other brands.. • 0.25" thick. • Neoprene padding creates a “gel like comfort”. • Adds a level of grip that is unlike any other belt system on the market.
