Featuring Realtee AP or Realtree Xtra camo, the Blackfin sunglasses by Costa Del Mar are designed to never slip, even when your face is covered in sweat or water. The Hydrolite co-injected lining keeps these glasses in place, and the flexible frame means serious comfort.
Not only are these sunglasses comfortable and reliable, but they provide 100 percent UV light blockage to protect your eyes from those harmful rays, and the 100 percent polarization kills glare to reduce eyestrain and make spotting fish and underwater cover a whole lot easier.
Other Blackfin features include: comfortable large fit; stainless-steel integral hinge; heavy-duty TR 90 nylon frame; scratch-resistant plastic or glass lenses; prescription-ready lenses; lifetime warranty. Hard case included.
