• While I can not explain the verbiage in the product description, I can relate my own personal experiences.
    Product sizing varies from manufacturer to manufacturer. The Costa Double Haul Sunglasses I just recently ordered fit me perfectly. I have a small hat size. The Double Haul frames are flexible enough to accommodate a more rounded shaped face. I have let a few friends try on the Costas to see the clarity of the lenses. The "flex" in the frames was not too tight for them.

  • The sizing is simply marked wrong in the product description. I have found this to be a problem with several different model descriptions of Costa sunglasses on STP. For example, the Hamlin model is listed as a Medium fit when the Costa website has it listed as an extra large. I own the Double Haul and can confirm they are a large fit. I have a large hat size, and I typically wear XL Costa glasses but the Double Haul fit me pretty well after extended use. I believe they have stretched a bit over time.
