Millie is a women's specific fit from Giro. At an incredible value, for $100 bucks you still get a high quality VIVID lens by Zeiss, extended vision to see what - or who- might be in your peripherals, and no compromising on style. We like Millie because her clean lines and cool colors still look like her more expensive two lens siblings. If you are looking to keep things simple with one lens, a Zeiss lens is the way to go.
