The FANTAIL PRO StoryAnglers know as well as anyone-the best can always get better. We've taken that sentiment to heart with the Costa Fantail PRO. The slimmed-down brother of the Blackfin PRO also boasts all the Costa PRO Series tech: a vented and fully-adjustable nose pad for a customizable fit; sweat channels and eyewire drains designed to help keep your vision clear; side shields, hooding, new stickier HydroliteA(R) and metal keeper slots to help to keep your frames on your face and the sweat and sun out of your eyes. Size & Fit GuideThe Costa sunglasses 'fit' guide is a range from Narrow, Regular to Wide with most people choosing Regular. Fit is a combination of both the size of the sunglasses and the features of the frame, together. The features of our sunglasses influence the way the sunglasses fit, like the hinges and temple construction. Use the 'fit' guide to select a Costa sunglass frame that will be comfortable and perform for you. Frame FitFrame SizeFrame Measurement1. Frame Width133mm2. Bridge Width15mm3. Lens Width60.0mm4.
