Design Philosophy Even though they bounce better than those with a few more years under their belt, mini-rippers still deserve top level protection. This is delivered in the form of multi layer memory foam padding, as used in the ever popular adult SingleTrack Protectors, allowing them to progress their riding even quicker than before. Protective Inserts Highly abrasion resistant Aramid impact panels mean that these protectors are designed to last, no matter what is thrown at them.
