What we’re expecting
The Ring Pro comes in sizes 5 to 14, weighing 3.3 to 4.8 grams depending on size, and uses the same sizing standard as the Ring Air, so existing owners can reuse their size.
The Ultrahuman Ring Pro comes in sizes 5 to 14 and four finishes: Raw Titanium, Aster Black, Bionic Gold, and Space Silver. Weight runs from 3.3 grams at the small end to 4.8 grams at the large end. Ultrahuman ships a free sizing kit before the ring, which is the right call for something you can't try on in a store.
