The Trimmers are adjustable and use a velcro-type hook-and-loop fastener to secure the trimmer in place-- so there will be some overlap of course. The Trimmers should feel secure, pressed up against your skin, but not tight or constricting. If the Trimmers are too tight, they can constrict movement. The trimmer does not have to be wrapped super tight in order to be effective.
