S1 Pro Knee Pad


The S1 Pro Knee Pads hit the market January 2016 after a 3 year design and development process. S1 Headquarters is very close to the ACDG practice facility so we were able to work with ACDG players on wear testing for the S1 Pro Knee Pad. We tested different designs and materials to see how they wore and functioned.


The S1 Pro Knee Pad was designed and constructed with 3 main areas in mind: Stability, Durability and Functionality.


Stability is very important in a knee pad to prevent injury by promoting controlled slides. We put Ortholite Memory Foam into the inner knee cup which upon impact molds to your knee and helps to stabilize the knee cap. By stabilizing the knee cap we are able to promote stability, prevent slippage of the knee pad and stop your knee from moving around in the knee cup. Instability in a knee pad puts unnecessary stress on your knee ligaments and leg muscles in a knee slide. The combination of our flat Cap with the Ortholite inner foam allows for stable, controlled slides that will prevent your knees from teetering back and forth.


We created the S1 Pro Knee Pad to last by using highly durable fabrics. We used Military grade ballistic nylon for the outershell material. We use a polymer enriched foam for the inner knee cup which helps absorb shock and not pack out as fast as lower quality foams. We triple stitched seams to prevent blow outs. We use a high quality, high abrasion plastic for the knee cap for longer life. Our butterfly flaps are made with a very tough neoprene that will not stretch and rip with repeated use. Our top straps are made with a high retention elastic that will not stretch out as quickly as other elastic materials.


We created our inner knee cup mold to be streamlined and deep fitting. By taking out the bulk on the side of the knee cup you will experience a streamlined look and feel to the S1 Pro Knee Pad. By using high density foam on our inner knee cup we are able to achieve the shock absorption of a thicker foam with a less bulky front profile. The articulating back flaps move separately to promote the a secure fit, less slippage and increased mobility without pinching. The S1 Pro Knee Pads also have a length adjustment on the top strap. The knee cap is affixed with top quality velcro that will not allow the cap to be torn off in game play but can be removed and replaced if needed.

Letter from a customer 5.20.16


My name is Lyka Fox, and I skate banked track roller derby. I have an S1 Lifer Helmet that, to be honest, I only bought because it was pretty (glitter, but still black? Perfect!). I’ve used triple 8 helmets previously, but this was my first S1.

I’m emailing to let you know just how impressed I am with it! Last night I took a hard fall and hit the back of my head harder than I have ever hit it in the 4 years I’ve been skating, and was totally fine. I was shocked, we were all shocked, I’m a very small skater and everyone says it’s usually pretty inaudible when I fall, but this time was very different. Later in the same game, I took a milder fall, but was booted in the side of the head full force by a team mates roller skate. No damage. I’m seriously amazed.

I don’t think I’ve ever composed an email to a company like this, but you guys are doing it right. I will 100% recommend S1 helmets to my newbies, and I will be buying a new helmet soon.

Thank you for what you do!
