I work outdoors in Florida and recently put this to the test with some skepticism. Just a small dab rubbed in… Day 1 trimming trees for 6+ hours, day 2 landscaping for 8 hours, day 3 hiking for 3 hours….I am 100% sold and totally amazed that this product can perform for hours on end. Do your body a favor and give it a try…you wont go back to regular deodorant.
