I use HS Scent-a-way detergent with regular cold wash, low tumble dry, and no fabric softener. I don't have high-end clothes, so there may be better detergent out there. I watch the wind closely when I hunt, but there are so many times when the wind is swirling and changes directions that I simply can't keep up with it. I'm not sure how well exactly this stuff works, but if I get only an extra second to shoot in animal, I will glad pay the small price. I've shot so many of my animals off-hand with a rifle under 50 yds, so this works for me.
