oi tape was built on a simple observation: most of us lose the ability to breathe through our nose the moment we fall asleep. Jaw drops open, tongue slides back, mouth breathing takes over — and so do snoring, dryness, light sleep, and grogginess.
Mouth taping isn't new; clinical literature on it goes back decades. What oi tape got right is comfort. Medical-grade silicone adhesive strong enough to stay put, woven mesh gentle enough for sensitive skin and facial hair, and a vented option so first-timers don't panic at the sealed feeling. Strip on, breathe through your nose, sleep deeper. Wake up less tired.
