The Oura Ring 4 Gold is a premium health and wellness tracking smart ring featuring an all-titanium construction with recessed interior sensors for maximum comfort. This exclusive Costco bundle includes the ring plus an additional charger for added convenience.

Powered by breakthrough Smart Sensing technology, the ring utilizes an 18-path multi-wavelength photoplethysmography (PPG) subsystem with infrared, red, and green LEDs to continuously monitor your health metrics. It tracks resting heart rate, heart rate variability (HRV), body temperature, blood oxygen levels, sleep stages, stress levels, and over 40 different activities with heart rate zones. The ring provides three comprehensive scores in the Oura app: Readiness Score for daily preparedness, Sleep Score for rest quality, and Activity Score for physical movement.

The ring features up to 8 days of battery life per charge, charges fully in up to 120 minutes, and stores up to two weeks of data depending on usage. It is water resistant to 100 meters (328 feet), making it suitable for swimming and water sports.
