I first encountered the Abus Hyban Urban Helmet when I went to RAD Power Bikes in Seattle to test ride their ebikes. They had a selection of these helmets for test riders. My brother and I both chose one, tried it on and looked at one another simultaneously said this is the most comfortable helmet, I can't believe it. RAD wasn't selling the helmets at the time (they are now). I found the helmet on line at Bike Tires Direct (best deal) and have never been happier with the comfort and integrated rear light.
I use this to bike commute, breathes well, the visor protects against sunlight, the quick adjust works smoothly and I like the added feature of the built-in light in the rear for safety. Extremely lightweight & stylish!
