You can order a Sizing Kit either together with your ring or separately to find your perfect fit.
The kit includes all available ring sizes made of lightweight plastic.
We recommend wearing the sizing ring for 24 hours to determine your ideal fit — a well-fitted ring ensures maximum data accuracy, comfort, and overall experience.
The sizing rings are made of plastic and may be sharper than the real ring.Read our tips on how to wear the Circular ring.
