Cordura denim provides road-rash resistance (which, thankfully, I’ve yet to test); and a Coolmax element helps regulate temperature on 80- and 90-degree days. With just a hint of stretch, the 12.5-ounce denim feels thick enough to be protective, but the slightly stiff quality of the front panel in the hip crease is a little bothersome in the riding position. Otherwise the fabric is comfortable enough for long rides or walking around. The CE Level 1 Seesmart knee armor is made of a flexible array of rubbery hexagonal cells; the pliabile, low-profile, breathable design makes them much more comfortable than other knee armor. While this makes me wonder if it’s as protective as more rigid options, it’s certainly more discreet. No robo-cop knees here!
