PowerBite – Custom-Fit Lifting Mouthguard
PowerBite is built for powerlifting and heavy gym training. It gives you a stable, even platform to clench on under load, shaped to your bite from your own impression instead of a boiled-to-guess fit.
Best for: Powerlifting and weightlifting.
Key Features:
- Stable clench platform: An even bite surface for heavy squats, deadlifts and presses, so your bite stays consistent rep after rep.
- Made from your impression: We ship you an at-home impression kit, make a model of your teeth and pressure-form PowerBite to it for a precise, secure fit.
- Pick your trim color: Clear, white, black, red, green, blue or gold.
- Easy reorders: Choose Impression Storage and we keep your model on file for future reorders. Expedited (3-day) lab service is available.
- Made in the USA: Finished by hand in our own lab and shipped with tracking.
