Review on Motorcycle Skeleton Protection Breathable Mouth Sharp by Dan West

I use them in muay thai and they work great. for 1/2 class. I sweat a lot (a lot) and after 30 minutes of hard cardio the mouth area fills with moisture and starts hitting me with water. But since they are cheap, I just take 2 and switch to clean. The design could have been better for my purposes and not so tight around the neck (I'm modifying one myself to see if that helps), but I like it. You can adjust the top elastic and keep it in place, which is a big problem for me with other masks. Plus, of course, the design is fun.
