The Gen 3 Pro Knee Pad from S1 is thoughtfully designed with comfort, durability, stability and function in mind. They have took great care in the design and development of this product and have been very excited to bring their vision to reality. After four years in development and thousands of hours of wear-testing, S1 are very proud to introduce the Gen 3 Pro Knee Pad. The Gen 3 Pro Knee Pad is the exact same design and function as the first 2 generations but they have expanded and fine tuned the sizing by adding additional sizes for a more customised fit, meaning you can get a perfect fit for any customer! So you know that they\'re going to be reliable, comfortable and of course they\'re going to look great on you! In this 3rd Generation of the S1 Pro Knee Pads, S1 have increased the area of inner Ortholite layer to go lower on the shin and higher onto the top of the knee for extra protection and comfort. They\'re always thinking about protecting us... How thoughtful of them!
