If I had money to blow on a full suit (preferably not the base layer stuff) I might give it a shot, but at $300-500 for a cold weather set-up, (because outside of the first couple weeks of the season it is mostly cold weather hunting) I can't see spending the extra cash on something that has not definitively been proven effective, at least to what I have looked into....I will stick with my sprays, airtight totes, and showering with a obsesssion bordering on fanatiscm for wind watching.....
