i have had the same pair of wool pants and coat. and i sprayed doe in heat scent on them about 10 years ago.. and when i am done at the end of the year.. i take them off and put them in a plastic bag.. and stuff them back in the locker in the back room.. and when the hunting season comes again next year i take them out . put them on and wear them again. i have never washed my coat or my wool pants since the day i bought them 10 years ago.. and i get a deer everyyear.
