Mission Belts use a ratcheting system to allow you to customize your perfect fit by making 1/4 inch micro adjustments. Resizing a Mission Belt is fast and easy. Simply lift the clasp, remove the buckle, measure the length that is right for you (be sure not to cut too much) and cut the strap. Then reinsert the strap into the buckle and close the clasp. Now you have the perfect custom-sized belt for your waist.
