This is a very hard to find pro model. Excellent condition. Size Med.
Used to ride in Seattle before I moved to CA about 15 years ago. Sold my bike when I moved here, but saved the helmet as I hoped I would one day ride again. Helmet has been sitting in my closet for that long, untouched. Inside padding is also in good shape. No smell, not beat up, or anything like that. This is a great price as same helmet today new costs $800++, even used ones go for over $500. Look on Ebay and verify.
If you don't know, Quantum F (now Quantum X) helmets are not as big and elongated as the other models. It is smaller profile helmet, thus the reason why I chose this specific model.
Cash only, pickup in Irvine. Make sure you know your helmet size before coming by. Text me if you are interested or want some closer pics.
Some additional info below:
Arai helmets include features like peel-away temple and cheek pad layers, as well as optional thicker or thinner pads, for further customization.
