Hebo Defender Knee Pads
This product was recommended by Ali Rizvi from Dream Superhero
Dakine Slayer Knee Pads
This product was recommended by Mia Clarke from InvertPro
A friend of mine bought one same time I did; his didn’t hold up as well, so there might be some durability issues – but they’re cheap enough that you can buy a replacement and still be less than some of the more expensive brands. And they fit and feel fantastic.
G-Form Pro X2 Knee Pad
This product was recommended by Tim Bigknee from SightsAndInsights
These knee pads come in both adult as well as children sizes, so you can get matching ones for the whole family. They include a SmartFlex feature which helps the knee pads stay flexible as you ride. The SmartFlex feature also hardens on impact with body-mapped impact-absorbing pads. The knee pads are moisture-wicking, with the UPF 50+ fabric keeping you dry and comfortable. They are also designed to provide you with ventilation and air circulation.
