Castelli Pro Thermal Skully H20542414 Review

One size? That's some nonsense. Even tightly dressed, it doesn't even get on the ear. And when I wear a helmet and turn my head, it contracts under my helmet leaving my head open. Well it's a joke! You would think they would be wrong to make it bigger as it could easily be rolled up to shorten if needed. But no, they went the cheap route. Bottom line: if you don't have a tiny head, don't buy one.
