I actually noticed that some of the helmets in the tour this year do look bigger as well. I thought maybe it was just me. On the other hand, there are some, maybe because of the shape of the helmet, that actually look smaller to me too. Team Sky, for instance, has some nice looking helmets that don't look overly bulky. Being on the lookout lately for a new helmet myself lately, I decided to see how much the Kask helmet worn by Sky goes for. Yeah, I'll pass on the $300+ bike helmet....
