According to the website, Fight Soap is an "ultra premium lineup of soap made for Mixed Martial Arts MMA fighters, strikers, and grapplers". The soap is made with some essential oils that are supposed to have anti bacterial properties. The soap comes in a small plastic container that makes it easy to toss in your gym bag.
To be honest I don't know if the soap is going to protect you from staph or ringworm any better than just good hygiene and clean mats, but I thought I would give it a try. I used their "Brazilian Bully" soap for a few days and I am pretty sure that it didn't improve my Jiu-Jitsu but it did get me nice and clean and it smells good.
If you are in the market for a nice soap, check it out. And if you have someone in your school who needs a little nudge in the direction of good hygiene maybe you could pick one up for them. Your training partners will thank you!
