Knee protector for snowboarding. Brand: ebs ebis Size: Unknown (no size listed) I used it when I was 174cm tall, and it fit perfectly. You can adjust it to some extent with the Velcro straps. There are also protectors with integrated knee pads, but I think it's better to have them separate so the pads don't shift during riding. There appear to be no noticeable scratches or stains.
