I use my AIRWAAV for powerlifting. It's been very helpful to help maintain the internal pressure I build. In fact, I don't even know what I used to do with my mouth/jaw before I had the AIRWAAV!

The difference that matters
If you've worn a mouthpiece before and hated it, this is almost certainly why. Jaw-advancing devices push your lower jaw forward all night. RX1 doesn't.
Custom fit, no waiting
No dentist visit, nothing to send in. You heat it, bite, and it forms to your teeth—even if you've never done this before. Watch exactly how:
A few seconds in hot water softens the patented fitting material. (~60 sec)
Bite down and it forms to your exact teeth. As it cools it locks the shape in. (~2 min)
A snug, custom fit that stays put all night. Most people feel the difference the first morning.
Works for all genders, ages 11 and up. Don't love your first mold? You've got a second mouthpiece—and 30 nights to get it right.
Not a gimmick. The research.
RX1's Reflex Technology was developed out of clinical sleep research led by Dr. Dena Garner at The Citadel—not a marketing department.

The AIRWAAV PX2 Performance Mouthpiece is praised for enhancing breathing techniques and performance, improving breathing and recovery during workouts, and offering a snug fit. However, opinions on the fit vary among customers.
Review topics: [].
"I KNEW I needed a mouth guard because I like to lift. I was going to cheap out and get whatever. Until Instagram realized that not only do I love lifting, but also Miami Vice, and up popped an add for this mouth piece. Of COURSE I bought it. And I love it! Snug fit, hitting PRs, and if you listen closely, you can hear Jan Hammer's instrumental hit playing, like when you hear the ocean when you hold a conch shell to your head. 10/10, would definitely recommend, and I need to stock up."
"The products fit well and I continue to use it today"
"Love it!"
"I use my PX2 for when I workout at home, but also for something as mundane as going for a casual walk around the neighborhood. I lost my original PX2 when it fell out of my pocket a few weeks ago, and my new one arrived in just a few days. Molded it in a few minutes, let it set for about 24 hours, and it fits just as good as the one I lost!"
"The mouthpiece cleaner works very well."
"My biggest issue with mouth guards in the past was sizing, I always found they were too bulky. The Airwaav is perfect, easy to put in and take out, and the fitting directions were super helpful!"
"I do CrossFit and purchased a PX1 mouthpiece initially. I felt it fit a little too loose so I emailed AIRWAAV asking to exchange for the PX2. They immediately responded and sent a PX2 completely free! The PX2 fits perfectly and I can tell my endurance is better during workouts. Thank you!"
"Seems to work great"
"High quality product, comfortable. It didn’t work for *me* for my intended purpose so i ended up returning but if you want a good mouth piece I still highly recommend this one!"
"If the guard is softer , more comfortable wear all night."
