1) Giro Urban
2) ~$30, it's been like 6 years since I bought it so I'm not sure of the exact price. Bought it at Dicks Sporting Goods.
3) I'm not pleased with its ventilation properties, and it's dark grey so now that I'm commuting more ideally I would like to get something more visible. I'm thinking of getting a higher-end helmet. Looked at the Bell Volt at my LBS, and it fit great... but the price doesn't seem like it will fit my wallet very well ($175) . Considering a Bell Array at the moment ($100). Might upgrade to Bell Sweep for the removable sun visor ($140).
