I've been using the Scent Crusher bag for the past 2 hunting seasons.
I agree. I've been amazed having deer come in from downwind and not spook. It's like they smell something, but it's not anything that they fear and they just go on about their business unalarmed.
I will say that it has destroyed the elastic shoulder straps on my bibs. No big deal. I just adjusted them and that tightened them up.
I don't nuke my clothes after every hunt, as the treatment is suppose to last awhile. If I feel I got any sweat on my clothes, if they got wet in the rain and I toss them into the dryer to dry, or if I know I'll be hunting in unfavorable/swirling winds I always nuke them.
