I've tried many brands of all natural deodorants (no aluminum, parabens, or glycerin). Jungleman is the only brand that 1) worked and 2) didn't cause skin irritation. It's odorless itself, so it doesn't clash with my cologne. It doesn't stop you from sweating (it's not an anti-antiperspirant—sweat is good!), but it effectively keeps smelly bacteria from growing.
