Sisu for bjj
I'm basically the only guy at my gym who doesn't have to take out their mouth guard to talk or drink water. I put my sisu guard in one time, and that's it. I don't take it off until after class. I can talk, I can breathe, I can drink water. It's great. After grappling for hours with multiple opponent's, I personally wouldn't want to keep taking my mouth guard in and out of my mouth. Sisu fixes that. Plus, it's light, and very protective too.
