I'm glad you brought this up. I bought some at this year's Buckarama, and I was working out the other night, sweating a lot --obviously--and after teh work out, I thought I would give it a test drive. I sprayed some off brand(Hide Out)I got last year on one arm pit, and DDW on the other. The DDW didn't kill my scent, but the other did. Antone else have any experience with it directly like this?
