I have fairly big round head, measuring around 62cm in circumference. After trying many helmets from different brands in this category, I tried the Evade III last, assuming based on reviews it would be too narrow. Surprisingly, it fit great. Can't say for sure whether I was lucky to find a round fit (not Classic), as the box doesn't say, but I think it is one of these. I applaud Specialized for offering helmets for people with rounder, bigger heads.
Ventilation, comfort and adjustability are all very good, but of course subjective. The price may seem steep, but when you are someone with a big round head living in a Western country, where mostly narrow helmets are sold, finding a good quality helmet that fits comfortably and safely is like finding gold. Worth every penny.
I have the blue one, which looks much shinier and darker than the pictures indicate.
