Weighs nothing, really comfortable, and easy to adjust. I don't see the point in sacrificing comfort (these work. very well. we have one on display in the shop which was involved in a 50km/h crash. The person dislocated a shoulder and cracked a rib, but seeing as he took 60% of the impact on his helmet, he came out pretty well.)
Phonak because I like to race in full Phonak kit to piss the commissaires and the local club president off.
