Review: Are Rapha Knee Pads comfortable, breathable and protective?

There’s a fair bit of trial and error required when it comes to finding the perfect set of knee pads for trail riding. They need to tick a lot of boxes. They can’t bunch up and pinch anywhere, they can’t have misplaced seams that create friction, they need to be flexible enough to move with you, not against you, as your knee comes up over the pedal stroke, they need to offer proper impact protection to the knee cap (and the upper shin if possible), they need to be durable so they don’t tear the first time you crash in them, and for the summer months, they need to be breathable. It’s not too much to ask, right?
