What HKC has to say:
These sunglasses are both stylish and cover your face well from the sun. They come with a built in cord and float to help prevent you from losing them. Quality eyewear on the water really makes a big different in protecting yourself from the sun's damage it can cause to your eyes. Find the Large Size to fit most heads wear an adjustable baseball cap in the neutral position as a point of reference on which size to go with. I personally am super picky on my sun glass choice and really enjoy these. They fit well under the Pro Wip 2.0 Helmet too!
