What kind of helmet do you use?

[Bad JuJu]

Another Giro head here, with a more round-shaped helmet, the Giro Xen. I've read that the rounder helmets slide better on the pavement--in case you actually hit it --and therefore are less likely to cause neck injuries, which we're all better off without.

Specialized Propero. It automatically adjusts and it's very cool in the heat of the day.

Alpina, it was that or a Giro and the Giro didn´t fit my head as well (shame as it looked a bit nicer). It´s a dark grey one and I bought it a couple of weeks ago to replace a six-year old helmet that hadn´t been in a crash but was startng to look a bit battered.
