S1 Pro Knee Pads - 32mm Thickness Note: S1 Pro Knee Pad Gen 4 is slightly less padded than Gen 4.5. If you want the thickest foam, go with the S1 Pro Knee Generation 4.5. The S1 Pro Knee Pad is thoughtfully designed with comfort, durability, stability and function in mind. We took great care in the design and development of this product and are very excited to bring our vision to reality. Four years in development and thousands of hours of wear testing we are very proud to introduce the Gen 3 S1 Pro Knee Pad. The Gen 3 Pro Knee pad is exactly the same in design and function as the first 2 generations but we have expanded and fine tuned the sizing by adding additional sizes for a more customized fit.
