## Features

- SIZE FIRST - Ultrahuman Ring sizes are different from standard ring sizes. Purchase sizing kit first to get the perfect ring AIR size. Ring AIR is available in 10 sizes from 5-14.
- TRYING THE SIZING RING - It is important to first use the sizing kit to determine the ring AIR size. Wear your ring sizer for at least 24 hours to know your fit. Wear the ring such that the engraved size number is toward the palm of your hand.
- FINDING THE CORRECT FINGER - For optimal comfort and advanced sleep tracking, we recommend you wear the Ultrahuman Ring AIR on your index, middle, or ring finger.
- FIT CHECK: You will get highest data accuracy and optimal comfort with a properly fitting Ultrahuman Ring. Here are a few simple ways to assess this — If you rotate the ring on your finger, it should not rotate freely.
- CHOOSE YOUR RING: After you've precisely determined your size using our sizing kit, head over to desertcart to order your Ultrahuman Smart Ring.
- BUILD QUALITY: While our sizing kit is made of high-grade plastic, the Ultrahuman Ring stands leagues apart in its material composition. Crafted from space grade titanium and coated with scratch-resistant tungsten Carbide, your Ultrahuman Smart Ring promises superior quality and durability.
