no problems staying warm on multi-hour rides in 2° C (35° F) to 10° C (50° F). toward the end of that range, it gets a little warm. i have a larger head, and after 60 minutes or so i find the compression of the cap to feel noticeable.

Rode in 42 degree weather and really appreciated the ear flaps

Cool in the Cool

I've used it once or twice and have initial impressions

I recently purchased the Castelli Difesa Thermal Cap and took it out on 40-48 degree road ride. The hat did a great job regulating temperature by keeping my head warm but also breathing well. The cap fits great under my helmet and the style matches exactly what I was looking for. The visor is the perfect length and does not interfere with visibility. I give this 4 stars because I really have to pull the ear flaps down to completely cover my ear. I do have a size large head and was worried about the ear coverage when buying this. I am interested to see how this fares in weather below 40 degrees. If you are looking for a hat that gives you a euro feel also protects against the elements, this hat is for you.
