A howler monkey is one of the fiercest beasts in the jungle. And these frames are worthy of the same name. The retro design of these pliable, TR-90 nylon frames take a nod from our classic Deep Blue frame but have thicker temple for more peripheral protection. The wraparound shape offers peripheral protection. The Howler's stainless-steel spring hinges make for a good fit with a variety of medium to large face shapes, and it comes with nose pads.
From the moment I opened the box and put them on I felt like they were custom made for my face. These frames are very comfortable and the lenses are SICK! I can honestly say that I can see clearer and with less eye strain than any other sunglasses have ever provided. You can wear these sunglasses all day without fatigue and the glass lenses are not heavy at all. I would recomend these Costa's to anyone looking for the ultimate in clearity from an optical quality lens.
