I wanted one that was comfortable, lite and keeps your head cool. I did get a chance to test fit one at LBS a while back so that's how I know there pretty comfortable and super lite. I just didnt have the $ at the time to buy it, plus the LBS is 1 hour away. That's why I ended up ordering it online. I would have loved to spend my money at the shop though. Guys, over here in Louisiana it gets hot, really hot , in the summertime. From the reading I've done, it's suppose to be one if the best breathing helmets out there, that was a key factor also.
