I have a bern with the winter kit that works well for me in the winter. Full disclosure time though, I dont pedal fast, I almost exclusively ride to work or across town for social time with friends. Basically I dont pedal at a pace that makes a lot of sweat if I'm dressed correctly. Everyone's style is different obviously. Much like cyccommute, I had several days in the spring of last year when the morning temps were 30 degrees colder than the afternoon temps, and I was too lazy to to carry a different liner ans switch them out for every ride. Bought a regular bike helmet that is adjustable like a hard hat so I can get a cap on and off easily under the helmet. If you like to push yourself and pedal hard then the bern or ski helmets might not work for you as well as they do for someone like me, and they only work well for me for about one season.
