I have the Scent-Lokgreen liners and wear my hunting clothes over them. Can I put an earth scent wafer on my outer hunting clothes?

You can put whatever you want on the outside , it won't affect the liner . BTW , since you're apparently trying to be "scent free" then why add a scent to yourself ? That makes no sense .

WASTE OF MONEY!

I use that waffer stuff all the time EARTH SENT perfectly fine to use anything ya want on the outside I've had my suit 3yrs and works GREAT !!!!!!!!
