After a few flops (size does not fit, scratches on the neck, pressed against his forehead ..) I buy only Uss. Since my last bright helmet was destroyed in a crash, I had only dark. I imagine that silver reflects a bit of sun and the head is not so hot. In the mud I wear rather mud-colored. After 20,000 Hm, I'm happy. (It always takes a week until I have adapted it perfectly to your head) The shipment was sensational. Ordered - delivered. One and a half days.
