It is important to first use the sizing kit to determine the Ring AIR size. Wear the ring such that the engraved size number is toward the palm of your hand.
Wear the Ultrahuman Sizing Kit ring over two nights or 48 hours to find your fit. This is an important step in understanding your ring size. The perfect ring size ensures that you have the most accurate readings.
You will get highest data accuracy and optimal comfort with a properly fitting Ultrahuman Ring. If you rotate the ring on your finger, it should not rotate freely.
For optimal comfort and advanced sleep tracking, we recommend you wear the Ultrahuman Ring AIR on your index, middle, or ring finger.
With the true-to-life color swatches, you can visualize and pick the color you like.
