📏 Nail your perfect fit before you commit — because your smart ring deserves precision!
The RingConn Gen 2 Air Sizing Kit offers 9 distinct sizes (6 to 14) to help you find the ideal fit for your RingConn Smart Ring. Designed for accuracy, it requires a 24+ hour wear test to ensure a snug, non-rotating fit that optimizes sensor performance. Made from premium-grade plastic, the sizing kit complements the aerospace-grade titanium smart ring, which boasts a scratch-resistant finish for durability. Compatible exclusively with RingConn Smart Rings, this kit guarantees you won’t settle for less than perfect.
