Jaw posture during sleep affects your nervous system, deep sleep quality, and how rested you feel in the morning. Reviv supports natural jaw positioning overnight so you wake up actually rested.
Tap everything that applies
A lot of athletes notice the same pattern. It often starts with the jaw.
When your jaw is out of alignment during sleep, your nervous system stays in a sympathetic (fight-or-flight) state. You toss, turn, and never reach deep recovery sleep.
Reviv maintains the Curve of Spee — the natural jaw position that signals your body to down-regulate into rest mode. The result: deeper sleep, lower nighttime heart rate, and waking up restored.
Individual results vary. R3 is designed to support natural jaw positioning during sleep.
Athletes who wear Reviv to sleep report falling asleep faster, staying asleep longer, and waking up without that groggy, unrested feeling. Your body actually recovers while you rest.

Balanced jaw positioning may support deeper sleep stages and a lower resting heart rate. You don't just sleep more — you wake up with the energy to attack your training.
Begin Better Sleep — $80“Only a few weeks in and I'm already sleeping and feeling so much better. I'm not waking up throughout the night anymore, and I feel more rested and energised in the morning.”
“I'm sleeping much deeper and feeling more rested. I started noticing the difference within the first week of wearing it at night.”
“I'm sleeping deeper and needing fewer hours to feel rested. It took about a week to get used to, but now I wouldn't be without it. I wear it every night before training days — if I sleep well, I perform well. Simple as that.”
Ken (EGK) developed Reviv after discovering how jaw posture impacted his own sleep, recovery, and energy. He found he was getting stronger and quicker without training.
The R3 is a structured mouthguard made from a flexible material designed to fit comfortably in your mouth. It's built to stretch the soft tissue and allow the jaw to naturally move where it wants — during sleep, while reading, while winding down.
