This ergonomic silicone ring features anatomically optimised contouring for enhanced comfort and performance. Available in three precisely calibrated sizes—45mm, 47.5mm, and 50mm inner diameters—each corresponds to outer dimensions of 65mm, 67.5mm, and 70mm respectively. The consistent 10mm thickness combined with a 20-30mm height profile creates a body-conforming design that distributes pressure evenly. Weights range from 30g to 40g depending on size selection. Constructed from premium-grade solid silicone, this ring delivers superior durability and flexibility. The thoughtfully engineered shape prioritises ergonomic support, making it an excellent choice for extended wear and optimal fit.
