The fit and monochrome change is fabulousThey to change dark enough for me and then change back fairly quickly. They look nice and like a good quality. Very happy with my purchase!My last pair was victim to coffee pot steam and I was devastated! Found these on here $20 less than the Harley that carried them. So happy!!!Not super dark but still is a great product and very fashionable.And not having to stop and change on a long trip was very nice.The glasses are cute if you are a passenger. However, as a driver, they are not very functional. The transition from clear to shadow is barely noticeable and the fit does not keep out the wind in low speed. My eyes watered at 40 mph.The glasses fit good and kept the wind out. Unfortunately, one of the lens fell out after the second time I wore them.
