Finding the right fit is crucial for the best experience with your Ultrahuman Ring AIR. This specially designed sizing kit includes ten unique sample sizes, helping you identify your ideal match before choosing a final size. A proper fit ensures comfort for all-day wear and prevents the ring from being too loose or too tight, which is vital for accurate health tracking.
Unlike standard ring sizes, Ultrahuman Ring AIR sizes are unique to the brand and tailored for a personalised fit. The kit’s ten sample rings cater to various finger sizes, ensuring reliable contact between your skin and the ring’s sensors. By using the sizing kit, you’re setting up your Ultrahuman Ring AIR to deliver dependable health insights from day one.
While the sizing rings are made from different materials than the final product, they mimic the feel and fit of the actual Ultrahuman Ring AIR.
