2000 miles with this helmet. positives are:
sizing seems right. i have a 58cm sized head; medium fits perfectly.
the harness that wraps around the back of the head. the ratchet dial is easy to use, secure, and well-made. the harness itself is designed to tilt above the ear for a more secure and comfortable fit. it's one of the best fitting helmets i've owned.
the bad-- it's slightly on the heavier side for those that care. the biggest issue was not being able to slide my glasses into the vents above the temples. the vents are too small and too narrow.
