It’s light, it’s well ventilated, and thus far (six or so months in) has proven very durable. Fit is true to form for Kask–I’m decidedly a L/XL, but can just barely squeeze into a M if it’s all the way loose (and if I don’t wear a cap). I have not yet tested the crashworthiness, but I’m comforted to see how well it covers the sides and rear of my head, as a good MTB helmet should. Quality has been typical Kask, which is to say perfect.
