These knee pads have just the right amount of protection but also are very comfortable at the same time. The best feature about them is also my biggest complaint: being that they fully wrap around your knee, you have to take your shoes off to pull them on, but the full wrap holds them in place perfectly and they are forgotten once you have them on. They do have some sort of plastic cup to protect the knee cap, but its far from a solid plastic bomb proof knee protection. I'm wearing them for down-hill, but since I'm also not doing 30 ft drops, I view them as more than adequate. I highly recommend them with a full-wrap shin guard for full leg protection.
