Sisu Mouth Guards: The Ultimate Wrestling Mouth Guard

The Sisu Aero Mouth Guard is the most high-tech, and comfortable mouth protection we carry at WrestlingMart. At WrestlingMart, we know how important it is to protect every wrestler’s mouth, jaws, and gums (not just the ones with braces). Unfortunately, many wrestlers shy away from dental protection because most mouth guards are very bulky, uncomfortable, and difficult to breathe in. Sisu’s revolutionary Diffusix technology allows you to keep all your teeth while being able to easily talk, breath, and even drink water. This product is amazingly lightweight and ultra-thin, but still manages to provide 30% better protection than traditional mouth protection. It’s non-compressing, perforated material distributes the impact force over the entire surface of the mouth guard itself. These perforations and special "crumple zones", when properly fitted, absorb energy direct forces away from your teeth, reducing the risk of dental injury. This product is revolutionizing mouthguards across the world of wrestling by offering more protection and less material in the wrestler’s mouth. Sporting a custom, remold-able fit and unmatched strength, these mouth guards are able to better protect your teeth. Now you will have the freedom to wrestle hard with confidence, and scrap harder without worrying about your teeth. Note: The SISU Aero mouth guard, made from a high tech material, brings you everything you ever wanted in a mouth guard. In fact, they're so comfortable; you might even forget you're wearing one!

    The Sisu Mouth Guard was a great product for my daughter as she had braces at the time. However, it was hard for her to keep in place.

    Bought this for my two boys, both have braces, molding for both caused it to stick to braces. Had to have them swish hot water in mouth to loosen and remove. Dipped in hot water bend top of guard back to much it not so tight when inserted into mouth. Mouth guards are harder plastic the most, but boys like it.

    This product is helpful because it is thin so it doesn't get in the way, and it molds easily to fit my mouth. It helps me breath easier than thicker ones.

    Product is very easy to fit to mouth. My son likes that it isn't nearly as bulky as traditional mouth guards, making it easier to breath. Also because of the size he is more willing to wear it.

    This mouthguard is revolutionary! You can breathe, eat and drink with them in. Makes it easier for you to focus on the match.

    My son is 13 but small he wrestles 86. Should he get the adult or youth mouth guard. I am guessing adult. I don’t think his mouth is going to get bigger.

    Yes, : ) I would recommend getting the adult SISU mouth gaurd.

    Can this mouth piece be used for braces my son is using a mouthpiece designed for kids with braces however he has a sinus condition and has trouble breathing through his nose. this other mouthpiece makes it very difficult for him to breathe

    You could wear these mouthguards with braces, but it will be a bit more work to get them molded. I will attach the link to Sisu's website with instructions on how to properly mold the mouthguard.
