Purchased 15-20 years ago. Selling because I don't use it. I opened it to check for strap deterioration, but it's unused. There's a space on the back where you can add a pad (additional pad not included). Can be used for bicycles, skateboards, airsoft, etc. (^^) b If you want to check any specific areas, or need more pictures, please comment. I will do my best to accommodate. Durable nylon airsoft knee pads with Velcro straps. - Color: Black - Material: Nylon - Design: With protector - Straps: Velcro - Application: For airsoft Thank you for looking.
