The first bonus of this helmet is its rounded shape. There has been some reports that pointy helmets, while very flashy looking, can increase the incidence of rotation injury in an accident, as the pointy shapes catch on the road surface, etc. See this link for a great resource on all things bike helmet.
A second bonus of this helmet is that I can fit my small ipod speakers right into two of the front vents. In the picture above you can just see one in the vent. Having some inspirational tunes on th eroad without the need for headphones? Priceless. The ability to have this sort of setup right on the helmet to easily go from trike to bike? Icing on the cake!
The helmet I went for is super high visibility yellow. Definitely plus points in the "dork" factor but if that means more visibility then so be it! This helmet has adequate vents without feeling too wide open, and thats even with me clogging up a few of the vents for tunes. the visor is a great addition and goes on and off the helmet with ease and is easily stored. On my past helmets I have usually pulled off the visor and lost it in the toolbox, but for the Citi I decided to leave it on. I was quite surprised how effective it is in keeping the rays (when they are shining!) out of the eyes.
Other notable features are a great head strap adjusting ratchet that works well and a rear mount for a blinkie. It should be noted that this helmet is slated to be DISCONTINUED, so get one now - BUT it is going to be replaced by a model named the Muni, which will have an even better adjustment system than the Citi.

Overall a great helmet for commuting - but good for weekend warrior and or club riding as well. It won't net you any "Lance points" for style, but oh well. Plus, it's much more satisfying to pull up alongside the full kit guys in a bright yellow rounded lid like the Citi before slamming it into the big ring and taking off anyway!
