I was down in Southern California recently and visited a new shop in downtown Ventura called the Iron and Resin Garage. I have to admit, it was like walking into a hipster motorcycle shop.
But they did have some cool men's and women's tees so naturally I had to take one home (above right). Unfortunately their website doesn't have any of the women's tops listed. Hopefully they'll add those to the site soon. This was the only women's moto top that I really liked, riding a moto myself.
Of course, they have a ton of nifty men's tees for that moto man in your life.
