I just use a scent free detergent (ALL: Free & Clear) and softener (Downy: Scent Free) on all my clothes, including underwear.I make sure that 2-3 loads before my hunting clothes are done in only scent free detergent w/ scent free softener, and scent free dryer sheets. I prefer scent-free year round, however, the wife likes to wash some of the little ones clothes in scented detergent and softener, but rarely during hunting season does any of that stuff get used.
