Costa Blackfin vs Costa Permit

Costa Del Mar's fishing sunglasses provide the clearest polarization on the market at a great price. Both the Costa Blackfin and the Costa Permit provide the quality that Costa Del Mar is known for. Take a look at our guide below to see which one is right for you!

Costa Blackfin

The Blackfin is slightly smaller than the Permit but with the same lens technology and frame composition. The frames are sleek and feel well made. They fit very comfortably on average to large sized heads. Without the venting holes that the Permits have, these sunglasses look and feel more streamline. These sunglasses handled every test we gave them out on the water and we looked good doing it.

Costa Permit

The Permit is slightly larger than the Blackfin and built with more Hydrolite to keep them secure. Additional venting on the sides provides reduced fog and heat retention. The layering of these lenses provides a high quality field of view and can help you spot marlin under the water more easily than ever. While larger than the Blackfin, the Permit felt more secure and comfortable on larger heads.

So Costa Blackfin or Costa Permit?

Both sunglasses provide advanced Costa technology and superior clarity with 580 lenses. The Permit provides some additional venting which will help with fogging and additional Hydrolite padding to keep them secure. Fit is the most important factor when deciding on sunglasses, so if you have a larger head, go with the Permit. If you can fit the narrower and lighter frames of the Blackfin and prefer medium sized sunglasses, then they are the right choice for you!
