Great fit for him or her - very light

  • Familiarity: I've put it through the wringer

We've purchased two pair of the Costa cook sunglasses from Backcountry. The fit is great for both his large face and her small face. The optics are what you would expect from Costa - flawless. These are super light and the nose and ear pads keep these on your face and make them very comfortable for all-day wear
