Review: SISU 2.4 Max Guard (Mouth Guard)

I’ve been on the hunt for a new mouth guard. My current mouth guard is this chunky thing that I can’t speak, drink, and barely breathe through. Kaci's mouth full of mouth guardI look like a monkey when I wear it.

I did some research for the best mouth guards on the market. My requirements were:

  • The mouth guard should—first and foremost—protect my teeth.
  • I should be able to breathe.
  • I should be able drink water.
  • Ideally, I can speak. I give feedback and ask questions all throughout class. In a perfect world, I’ll be able to leave my mouth guard in my mouth at all times. When you’ve been sweating (and sweat on by your partner) the last thing you want to do is reach into your mouth to pull out your mouth guard.
  • My final nice to have is that the manufacturer’s logo or name shouldn’t be written across my teeth. I’d like to choose when to advertise. Thanks.

Last week the new mouth guard arrived: the SISU 2.4 Max Guard (in blue)! It came completely flat. At first I was a little confused, but it only took a quick look through the instructions and I was on my way. I’ve done the boil-and-fit scenario with previous mouth guards. The instructions were similar to those experiences and very straight forward. It’s not very complicated and I doubt many would have any issue with it.

The main difference with this mouth guard compared to others is you fit the entire piece of plastic around your teeth. It is 100% customized to your mouth. There’s very little base design that you work around. I should mention I also have a pretty small mouth. Most guards feel oversized in my mouth. The SISU is slim, but sturdy. There’s plenty of plastic to completely cover your teeth, but not so much that it overpowers your mouth.

As soon as the guard started to set around my teeth, I knew I was going to be a satisfied customer.

Just listen to the difference:

Tonight was my first Krav Maga level 2 class with the new mouth guard. It was so comfortable. I could breathe, drink, and speak! I didn’t have to take it out of my mouth once and my partner could understand me the whole time.

We sparred at the end of class to practice our defenses and my partner was vicious. She let me have it. The guard was snug and secure. I could bite down without any issues and I never once thought about it while we were sparring.

I’m sold.

The one tiny downside is that the mouth guard is more expensive than any mouth guard I’ve ever purchased. It ranges from $22-35 on Amazon, but, in my opinion, was completely worth it. This is mouth guard number four for me and I’d buy the SISU 2.4 Max Guard again.

Let me know if you have any experience with the SISU mouth guard or if you end up buying it! I’d love to hear your experience.

  1. Yes! Love my SISU! I’ve tried several other mouth guards including ones made by my dentist, and nothing compares to my sisu.
