Same story as with my goggles that are for sale in another thread - I left helmet (and goggles) home and had to buy new helmet during the trip. Helmet has been worn less then 15 times. I think I always had my balaclava on when I wore helmet, so insides are very clean. I was just looking at the shell and found a couple of tiny scratches near back vent openings - shown in the pictures below. Helmet is size L (58-60cm). Helmet comes with a soft carrying pouch.
Price is $50 shipped via USPS Priority Mail anywhere in the USA (2-3 day delivery time) and includes tracking number. Or pick it up in person in NYC and I'll drop a price a bit as I won't have to do any shipping.
Any questions or if you need more images, do not hesitate to email me.
