The advertisement states "one size" but sisu offer 3 different...anyone know what one they mean?

The SISU Aero small is recommended for those under five feet, the Aero medium is recommended for those between five and six feet, the Aero large is recommended for those six feet and above.

Hi, am looking for a mouthguard for my 11 year old son who plays rugby, that is also bpa and bsp free. Would one of these suit?

Hello again, I have now received a response from the manufacturers of Sisu mouthguards - please see below... "The material is a surgical grade thermoplastic that contains no harmful chemicals: No bpa, bps, phthalates, pvc, or latex. Our mouthguard material has been tested by an independent, third party organization, NAMSA for 'irritation and skin sensitization'. It passed based on the requirements of the International Organization for Standardization 10993-10 (biological evaluation of medical devices). The material has not shown to cause irritation or skin sensitization. However, if you have a unique or extraordinary allergy or a sensitivity to any chemical, extreme caution is recommended." I hope this answers your query. Also, if ordering for an 11 year old, you will need to order the adult size Aero or Max not the junior. Kindest regards Wendy at Trust Parts

Hi looking for a mouth guard for 13 year old girl hockey which size and style would be best thanks

Is she wearing a full-face cage? If no, the SISU Max guard is the best choice. If yes, she can wear either the SISU Aero Medium or the the SISU Max guard.
