Our camouflage utility uniforms were pre-treated with permethrin and on the little hang tag it advised us that the more we washed them, the less effective they'd be. So, taking that into account, last turkey season I did as GomerPyle did and treated them and tried to avoid washing if I could stand it. A turkey ain't gonna wind you, so as long as you can tolerate your own musk, you're good to go.
