There is a youtube video I will try and find in a minute. But, first you loop one end of the Velcro around your belt loop on the left side. Then feed the belt to the right thru the loops all around your waist back to the front. To tighten, take the other Velcro end and loop thru the belt loop on your right side and tighten. Belt Is very sleek and can not move at that point. Unless you have wide loops, you will want the outdoor applications version. I wear the medium and I have a 33" waist. If you are close on the sizes ,get the next larger size as they are a close fit. Very comfortable.
