In the winter, I have a hat down, so it is tight even if the adjustment band is full. There should be a type that extends from 63 to 64 cm. I improved the band, I used a clasp on the end and managed somehow. Otherwise it is OK. Since the head is large, it is good if LL size is available.
Since eaves are transparent, even if there is an obstacle above, you can recognize it safely and can do it immediately. Ventilation is good, head sweat is less than other helmets. I like it although it is the second purchase this time.
