My hunting clothing gets washed in the normal stuff the wife uses although I have told her to not use the brightener stuff. Then they get hung out on the screen porch for a couple weeks. Before I had the screen porch they hung in one of those little barn type sheds for a couple weeks and out side on nice days to air out.
As for watching the wind I took some sewing thread about 6 inches doubled it to make a loop then ran the ends thru the U piece sticking thru the upper sling swivel's. All my rifles have that handy wind indicator on them. I like the heavier thread size as it will last longer and when it frays it works even better.
Remember they are hunting clothes not fuel filling, not restaurant going not bar hopping clothing.
