Charles M.wrote a review of Giro Phase Helmet on March 29, 2012
Great helmet if you have a big head, adjustment is easy, just a little tricky at first to get it to stay at the size you want. I have a big head, especially the ridge on top, and it fit great. Ventilation was great too. Also did it's job when I needed it too, flew over the handlebars and nailed a rock with my head, broke the helmet, head wasn't too bad. I would buy it again.
