Years ago I was shooting bow in an outdoor archery range..some new guy started shooting at the last target versus the first and blew some whitetail doe's my way..I had a bright RED Coke t-shirt on...I stood downwind motionless beside a tree--they walked past me at less than 10 yards..had no idea I was there...so yes--just like the scent sprays everyone buys..if you watch the wind you don't need a scent spray..

I do think it can help break up your outline some..but if you are walking ridge tops or something else and letting game spot you..don't care if you have $5000 camo on--you will be seen..
