SISU Mouth Guard Aero - Ultra Slim Gumshield for Adults & Kids - Custom Fit Rugby Gum Shield- A Remouldable Sports Mouthguard for Boxing, MMA, Hockey

Highly recommend. This mouth guard is not as big as other mouth guards and my son finds it a lot more comfortable. After trying other products, this is the first one he will leaving in his mouth without fiddling with it.

If your looking at this, you don’t really need a review. This is a better model than most, but will need you to do some work the mold it to your satisfaction. My daughter is a roller derby skater so needs a high quality item to protect her lovely smile. If your the same, this is the item for you. This is the second one she has used.

Takes a couple of times to get right. Difficult to choose a Mouthguard size based on your height.Good idea for a product, great that it can be remoulded.

Worked just as needed for my nephew. Stops him fiddling with and chewing his gumshield between set pieces, especially during the game

This is amazingly lightweight and transforms the experience of wearing a mouth guard, bit of a faff to fit and took a few goes. Very hard to fit it so that the relatively hard plastic doesn't dig in and the little holes are properly aligned and wonder if it might gouge your gums a bit with any serious impact but still so wonderfully thin and lightweight.

A bit more expensive, but very comfortable. Has been refitted a couple of times and still works.

This is the second year we've used this mouthguard. My kids 100% prefer them to more traditional style and make so much less fuss. Unlike others, I find them easier to get the fit right that the gel ones. You can get a much tighter fit which properbly stays in place. This year we reused my daughters and it looks as good as new.

Usually mouthgards feel horrible, make it hard to breathe and I cant wait to take them out. with this one I can happily get through a whole jiu jitsu sparring without any discomfort!
