To mount a pouch on the belt, loosen the four 2mm screws to widen the belt slot. We recommend loosening the 5mm center screw first and rotating the pouch so you have clear access to the four screws. HOW TO CHOOSE THE RIGHT BELT SIZE. Measure your waist where you plan to wear the belt. Use a soft tape measure, run it around your body over your pants (not bare skin), and pull it snug but not tight. Write that number down. Add 9 inches (about 23 cm) to your waist measurement. That total is the belt length you need. The extra 9 inches is the overlap, the section where the outer belt’s hook-and-loop wraps around and grips the inner belt. Less than 9 inches of contact and the belt won’t hold securely. Compare your total to the OAL column below and pick the size whose OAL is equal to or just larger than your number. Example: a 36″ waist plus 9″ overlap is 45. That means you need at least a Large (46.5 OAL). Fits a waist up to. 38.5 (97.79 cm). 9 (22.86 cm). 29.5 (75 cm). 43 (109.22 cm). 34 (86.4 cm). 46.5 (118.11 cm). 37.5 (95.3 cm). 41 (104.1 cm). 54 (137.16 cm). 45 (114.3 cm). Tip: if your waist falls between two sizes, go up. Extra overlap just means more hook-and-loop contact, which holds even better. If the belt is too short, you won’t have enough Velcro contact to keep it closed.
