I sweat like a 300 lb+ fat kid in a buffett line, and I have learned the recipe to defeat sweaty pits and BO.
1. apply Old Spice high endurance when your pits are dry. If you put it on immediately after you shower, it's like writing on a piece of paper with no lead in your pencil
2. invest in Certain Dri, this stuff really works. I took down 2 bottles of it down with me on the rock, and I went through 1 1/2.
Stay dry
