No, but you can. Everything from the fabric to the placement of the conduit system has been very carefully designed. Adjust the conduit when you put the underwear on and it won't stretch or wear out. One of the best features of UFM Underwear is the adjustability option. If you are going to work, you may want to wear the conduit loose. If you are getting ready to work out or go for a jog, you may want to tighten it. Adjustability is an option.
