POC Joint VPD Knee Protector.
An outstanding piece of kit. I haven't used knee protectors before so I don't have much to compare these to but in my view you can't go wrong with the POCs. They are comfortable, lightweight, breathable and whilst I haven't yet crashed wearing them they look up to the job when the inevitable happens. After wearing them for a few minutes you forget you have them on except for slightly warm knees but they give you the confidence that they will protect you in a crash. After 20+mile rides they do not move and they do not rub they are perfect. If you want a knee protector for general XC use I can't recommend these enough!!!!!
