I just got back into riding after a 10 year hiatus. I always wore a kidney belt when I was a kid, but I never really knew what it did. Do people still wear them? I don't see any of the pro SX/MX riders wearing them. Do people wear them under their jerseys now? Are they mainly for lower back support or is there something internal that they protect (kidneys)? If I don't wear one will the only consequence be a sore lower back? I'm starting to get suspicious that they exist to make more money for the apparrel companies.
Thanks!
Thanks!
