I am a professional pickle jar opener and have cracked 7 teeth while competing. I now have no worries, as i can open 100's of pickle jars in one sitting and keep my teeth protected. I am now so confident in this product I have started using it in my MMA and BJJ classes with no issues. 
 
TLDR, If it can deal with pickle jar competitions, it can deal with Brock Lesnar.

Such a huge difference from what we used last season... my son was constantly pulling it out of his mouth even to call the start of play in football, which was a bit of a problem, since he needed his hands free to catch the ball. He also chewed on his old one, which was gross. Got this for Lacrosse season and he wore it for hours, didn't take it out once, and I couldn't even tell he was wearing it. Took 3 times to get the right mold... not bad considering he is just 6 years old.

Best Mouth Guard Ever!

I purchased one for each of my son's last year while they were playing lacrosse at NCAA DII Adams State. When one of them lost theirs recently, he asked for a replacement. When I gave him the choice of what mouth guard he wanted, he emphatically asked for another Aero Guard. When given the choice of any mouth guard, it says a lot when he liked it so much he wanted the same one. Thanks for a great product! Now if we can include loss prevention as a feature, we'd be set but you wouldn't make any money that way :)

So good I bought a 2nd one

I don't know WHY you wouldn't purchase this product for yourself/your child. I literally got SHOT on from like FIVE FEET away from the other person and it hit my mouth directly and i had the fattest lip and my teeth are literally perfect. This is the only mouth guard to purchase PERIOD.

The only mouth guard to get

I use this mouth guard for Jiu Jitsu. When you're competing the last thing you want to worry about is your mouth guard sliding around. I like not having to "bite down" to keep it in and that I can actually close my lips normally instead of having that "I'm holding an orange slice between my teeth" feel.

Highly Recommend

Thank you! Our daughter is a lacrosse goalie. She has had issues with mouth guards in the past. She can be heard easier and clearer with her Aero Guard. We actually bought 2 so she has a spare ready to mold if the 1st one starts to have issues. She is very happy! Thank you!

The girl child loves it!

Wonderful.  Easy to breathe.   Thin.  I use for sports AND sleep as a bite guard.
