PX1 and PX2 do the same job. Both help you breathe better, clench stronger, and stay calm. So how do you pick the right performance mouthpiece for athletes like you? It comes down to one thing: how you want it to feel.
Below, you'll see what the two mouthpieces share, how their fits differ, which one suits your training style, and what to do if you still can't decide.
What PX1 and PX2 Have in Common
Let's clear this up first: PX1 and PX2 deliver exactly the same performance benefits. Both are built around three of them:
-
Breathe Better to Endure Longer: AIRWAAV lowers respiratory rate by up to 20% (peer-reviewed).
-
Clench Stronger to Perform Better: AIRWAAV’s patented bite bar supports better jaw positioning, so when you clench, it activates a neuromuscular response that engages more muscles and helps unlock more strength during heavy effort.
-
Stay Calm to Recover Faster: AIRWAAV reduces post-exercise cortisol by up to 50% (peer-reviewed).
Both are built on 15+ years of peer-reviewed research, developed with Dr. Dena Garner, a researcher in muscle physiology and airway performance. So you're not choosing between results. You're choosing a fit.
The One Real Difference: How Each One Fits
The only thing that changes between the two is the fit. Here's how they compare side by side.

Think of it like choosing between two pairs of the same shoe in different fits. The shoe does the same job either way; you just pick the one that feels right on you.
Which Mouthpiece Fits Your Training Style?
Your sport shapes how you'll use a mouthpiece, so here's how to think about the fit for each one.
Strength Training and Powerlifting
If you clench hard under heavy loads, PX2's snug, locked-in fit is built for you. Heavy lifters and hard clenchers tend to prefer it. Like a lighter feel even on big lifts? PX1 gives you the same benefits as a mouthpiece for strength training.
Running and Endurance
Long runs mean long wear time, so comfort over the miles matters most. If you'd rather barely notice it, PX1's relaxed, open fit is a natural match. If you like it held firmly in place, go PX2.
Either way, you get a mouthpiece for running endurance that helps you breathe better to endure longer.
Triathlon
Triathletes train long and often, so when you're choosing a mouthpiece for triathletes, pick the fit you'll be happy wearing for hours on the bike and run. Pair it with Nasal Strips, and you've got the Performance System, a dual-airway advantage in training. The adhesive holds through sweat and 8-10 hours of wear.
CrossFit, HIIT and HYROX
Mixed training means heavy lifts one minute and hard conditioning the next. This is where the Hybrid Pack makes sense: you get both fits and can grab whichever feels right for the day.
Baseball and Softball
At the plate, the goal is a relaxed jaw and calm focus, not endurance. Choose the fit that helps you stay loose and composed: PX1 if you like it light, PX2 if you like it locked in.
Notice the pattern? Your sport matters less than how you like your mouthpiece to feel.
Still Not Sure? Answer These Three Questions
If you're still on the fence, these three quick questions will point you to the right pick:
|
Ask yourself |
If yes, choose |
|
Do I clench hard, or want it locked firmly in place? |
PX2 |
|
Do I want something I barely notice? |
PX1 |
|
Do I mix lifting and conditioning, or just can't decide? |
Performance Hybrid Pack |
The Hybrid Pack is the easy answer when you're undecided. You get both fits in one pack, so you can try each and keep switching between them.
Tips for Your First Few Sessions
Whichever fit you choose, a little setup helps it feel natural fast:
-
Fit it first: Follow the how-to-fit & use guide before you train with it.
-
Start easy: Wear it for warm-ups and lighter work before a big session.
-
Give it a few sessions: Breathing and bracing with a mouthpiece takes a little getting used to.
-
Add Nasal Strips: They complete the Performance System for training.
Before long, it'll feel like a normal part of your gear.
FAQs
Is PX2 better than PX1?
No. They have identical performance benefits. PX2 just has a snugger, locked-in fit.
Can I use one mouthpiece for both lifting and running?
Yes. Both deliver the same benefits in any training. Pick the fit you like best, or get the Hybrid Pack if you want both.
Is a performance mouthpiece the same as a sports mouthguard?
No. Sports mouthguards are built mainly for impact protection in contact sports. A performance mouthpiece is built for breathing, clenching, and staying calm while you train.
Can I use my HSA or FSA?
Yes. AIRWAAV is HSA/FSA eligible.
