i only wear it as an outter layer...

only because Germ was kind enough to send me 2 suits of it...

i guess if you double or triple layer the stuff, you would beable to "contain" more scent..if anything got past the base layers..

or the base layers had scent on the outside of them or something of that nature...

in the end, your walking around in a PILE of cash lol...guess if you were super anal about scent control, and believed in the stuff doubling the stuff could only help....
