I guess time has come and pushed my luck for 30 years now without them. I'm thinking of getting knee pads. I want something that holds well in place for 2h + rides. I want something that is as little restrictive as possible to pedal. I ride mostly XC- Trails here on the east coast, not much jumping for me other than the occasional jumps.
I wear 7iDP pads for long rides - hardly know they are there. I want to say they are Transition pads. Sam Hill Lites look pretty good too. https://www.jensonusa.com/Leg-Armor?brand=7IDP
