Too bulky but it does the job

The rubber can be soften quickly when soaked in hot water as claim. I found it too bulky for me to be sparring comfortably with it. But it's cheap and comes with a storage case.

Hi, K.P

Thank you for your purchasing with us and your review!

On the behalf of Boxing team, I'm sorry to hear that our mouth guard is too bulky for you. If you're unsatisfied with our product, feel free to contact us in order to return/refund as it is our policy to guarantee your satisfaction.

Der mit Abstand schlechteste Mundschutz den ich je in meinem Leben verwendet habe. Ich habe 10 mal versucht ihn anzupassen aber es hat nicht geklappt eine bodenlose Frechheit.

Mundschutz NICHT zu empfehlen

Ihr bekommt schlecht Luft, ich konnte noch kaum Atmen. Anschließend habe ich während des Trainings ihn rausgenommen und weggeworfen. Kauft es nicht nur, weil es billig ist.

Leider nicht passend

Geholt für meinen 10 Jährigen Sohn und einer Körpergröße von 140 cm, also eigentlich passend aber sie passt leider mal so garnicht....von der Länge viel zu lang und von der Breite der Backenzähne viel zu schmal. Haben jetzt mehrmals versucht sie irgendwie passend zu machen aber leider ohne Erfolg.....Geht leider ohne sie überhaupt mal benutzt zu haben in die Tonne.

No está mal del todo

El producto en sí no es malo, pero es muy difícil de modelar. He necesitado 4 protectores hasta que he conseguido un resultado decente

esta bien

Yo la estoy usando por el bruxismo, ya que al llevar aparato no puedo usar la férula que tenía, y para un apaño esta bien.

No se sujeta

La premisa de un protector bucal simple de artes marciales es que se quede sujeto en la mandíbula superior, que no se mueva y este no lo hace. El material tampoco es bueno pues se deforma con facilidad, solo llevo una semana usándolo. Puede que me haya pasado solo a mí, pero desde luego personalmente no lo recomiendo ni para empezar.

Difícil de adaptar

Se deforma con facilidad; dura poco y no es cierto cómodo en tallas para niños

New, safer design

Our mouthguard complies with the new XP S72-427 standard, which stipulates the following features: - Thicker to prevent perforation. - Built-in breathing channel so that you can breathe even when your jaw is closed. - Meshing of the upper and lower teeth to more effectively hold the jaw in place (protection against fractures). -A gum covering to stop the teeth from coming loose.

Directions for use

Always wear your mouthguard during training sessions and competitions. To mold your mouthguard correctly, soak it in boiling water for exactly the amount of time it says on the instructions. This time will be indicated in the instructions and may vary from model to model. Watch the video tutorial to find out how to mold your mouthguard. To guarantee good protection, your mouthguard should stay in place when you open your mouth.

Care instructions

Wash in fresh water. Leave to dry naturally before putting it back in its storage box (original box). For optimal protection, replace your mouthguard at least once per year or as soon as it starts to show signs of wear.

Choosing the right size

S: Users 3'7" to 4'7" tall (CHILD) M: Users 4'7" to 5'7" tall L: Users over 5'7" tall



Storage instructions

Store your mouthguard in its case (sold with the product).
