Becomes brand new in hot water. - It’s really easy to mould multiple times until you’re happy. I was worried that once it stuck together I wouldn’t be able to separate it, as that’s what they warn might happen but luckily for me it didn’t. Just boiling water and it completely unfolded. It’s thin and doesn’t get much in the way. Very easy to breathe. For boxing and other sports where you get hit in the face you might prefer a bulkier mouth guard with some shoc absorbance. This just holds everything together firmly. ## Features - ULTRA SLIM YET STRONG: At just 1.6mm thin, SISU Aero is 50% slimmer than conventional rugby mouth guard , yet 30% stronger with 8x tensile strength.

Would one of these suit?** A: 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 **Q: Hi looking for a mouth guard for 13 year old girl hockey which size and style would be best thanks** A: 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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great fit *by Y***N on 23 April 2026* Best gum shield for roller derby you can get ### ⭐⭐⭐⭐⭐ Easy breathing.

I was worried that once it stuck together I wouldn’t be able to separate it, as that’s what they warn might happen but luckily for me it didn’t. Just boiling water and it completely unfolded.

This just holds everything together firmly. ### ⭐⭐⭐⭐ Best off the shelf mouth guard I've ever owned *by J***B on 10 January 2021* Once moulded correctly this is the best off the self mouthguard I have ever owned. I can put it in, train, drink, talk and breath. With no issues. Only reason its a 4 star is it took me about 10 attempts to get the moulding right. Fortunately that doesn't effect the performance. ## Frequently Bought Together - SISU Aero Medium Mouthguard, Snow White - 1.6mm Thin - Custom-Molded Fit - Slim Design - Remoldable Up to 20 Times - for Team Sports - Non Toxic - SISU Mouthguard Case - Lightweight & Durable - Fits Aero, Max, Junior & Tether Mouthguards - Style May Vary - Bulletproof: World’s Thinnest Most Breathable Mouthguard is 3X Stronger!
