Anatomically Designed for Men. SR anatomical saddles for MEN have a wider pressure relief zone than womens saddles, ergonomically designed to avoid the compression of pudendal nerves and arteries, as well as the prostate. This results in an optimal blood flow to the genitals and no more feelings of numbness. Royal Vacuum Light is a SR proprietary production technology enabling the saddle to be: 100% sealed therefore reducing the risk that water or moisture is absorbed by the saddles foam. Up to 20% lighter than ordinary saddles of the same category. More Comfortable. More comformtable thanks to the use of a high quality polyurethane foam. Becoz saddles feature our own revolutionary Corkgel, an innovative material based on a bio sourced polyurethane gel combined with natural cork.
