Finding a great mouth guard which offers great protection and comfort can be a challenge - especially as many of them are so bulky.
That's why we're big fans of SISU.
These are super comfortable and only 1.6mm thin, making them thin enough to talk, breathe and drink normally. Their tag line is "More protection, less mouthguard".
They are also remoldable upto 20 times so you can update the fit as their teeth change!
What about protection?
Not only does the SISU come with a $35,000 limited 1-year dental warranty from the manufacturer (which you register online), it features Crumple Zones on the front to absorb impact forces, and is powered by Diffusix technology, which makes it even stronger.
Unlike most gum shields on the market, the SISU actually comes flat. You still fit by dipping in hot water (instructions in the pack), but its design allows for a most customised fit, so you get better protection and more comfort.
The SISU Aero is best suited to athletes aged 11+.
