The Next Stage Of Hydro Pump Evolution! The Hydromax X-series is the next stage of Hydro Pump evolution. Developing the innovative Bathmate, the new bellows pump and valve give 35% more power for even greater gains with more safety and comfort. The new Hydromax X20 is the latest addition to the bathmate range. The Hydromax X20 has the same great features as the Hydromax X30 and X40 but is a little smaller, designed for guys whose penis in no longer than 6 inches. By introducing new materials into the mix Bathmate have been able to create a unique bellows system that is not only stronger and more durable but also gives more flexibility, allowing you to create greater suction with less effort. The internal bellows size has also been increased and the number of convolutes reduced giving you plenty of room for increased girth expansion. The addition of their new super soft comfort pads have been a revelation in providing a tighter and more comfortable seal against the body, this means less pumping and less loss of suction. The soft-touch outer edge feels great against the body and the rigid inner tube provides a strong and sturdy shield around your penis from the inside of the bellows. Comfort pads are completely removable for easy cleaning and general hygiene. Probably the most important change they've made, and certainly the most technically challenging, has been the re-engineering of the valve that controls the flow of water out of the device. By adding a new latch (or switch) to the valve you can now close the valve to prevent water escaping when filling. This small but important change now allows you to fill the device with only one hand leaving the other free to sort yourself out or get your accessories ready. they have also designed the new valve to hold pressure for longer and introduced a slow pressure release mechanism to ensure that you don't over pump, keeping you safe at all times. The clear measuring guide on the front of the device has been re-designed to include both imperial and metric measurements giving you the ability to track your progress in a scale that you understand
