Let's face it not all bike seats were intended for all day riding. The team at Serfas has developed the Dual Density technology. It begins with a top layer of Reactive gel for cushiony comfort. Then it adds a soft open–cell padding layer that's merged to denser closed–cell padding. A rubber insert molded into the base absorbs shock. The whole design supports the rider's weight for a longer time. The woman's specific shape uses an anatomic groove that alleviates pelvic discomfort. Why ride with a seat that leaves you with a pain in the butt? Try this one out you'll be amazed at the comfort.
