Snap-Fit Clear Mouthguard

“
Best fit I have ever had, worked fine first attempt. Forget I even have it in while sparring, does not affect my breathing, and I like that it properly protects the gums as well.
”

“
The fit is so close that I have to flick my finger behind it to get it out — it is not budging anywhere. The fit is tight but doesn't rub, its thin design feels weightless and barely there yet the outer shell is immensely strong.
”

“
By far the most comfortable mouthguard — I have no gag reflex with it, however most mouthguards do that for me. The fit was perfect and it can still be used as a backup.
”

“
Best gumshield for rugby. Due to the tight fit, it is easier to talk and shout and doesn't move whilst doing so. The fitting kit is so easy to use. Definitely recommend.
