Es excelente y un buen precioVery poor quality.I don’t recommend this productIt’s a bit tight on me, somehow there are not many selection for bigger face like me for 580G blue mirror. When come to Omni fit it’s even lesser choice. A suggestion to Costa is to invent a Omni fit nose pad (just like what Oakley does) to fit into different model so that we have more choices and boost sales!I recently ordered a pair of Costa Del Mar Tuna Alley sunglasses with the polarized copper mirrored plastic lenses. In retrospect the price was too good to be true.What I received were fakes as there was not a 580 engraved in the right lens (if you are wearing the glasses). This is the second pair of Cost Del Mar sunglasses I have purchased and immediately returned to Amazon as they were both cheap knockoffs.The packaging for both sets of sunglasses looked as if they were picked out of a recycling bin. One of the actual Costa Del Mar boxes appeared to have water damage and had a printed label NEW as if it was created on a home printer.The sunglasses themselves had signs of being used as there were no clear plastic sleeves on the arms which are typical for Costa Del Mar products as well as a sticker on the lens stating they were NEW.I usually have great services from Amazon.com but this one has slipped by their QC folks.I recommend purchasing Costa del Mar products directly from their website or a authorized dealer.I like the sunglasses. There well built and light. One problem I had was the place that I bought them from sent me the global fit or Asian fit which pulls it really far from your face.First of all the pantent number is printed wrong, should be 2 lines of info which is clearly showed correct in the product picture. The 580p is etched into the lense and dont get me wrong it looks great to look through but im pretty sure the frames are fake but real lenses. Just order from the costa site thats what im doing lol. Will be used as a back up pair because im not dealing with amazon's bsMy husband loves his new costas!!!! Great price, delivered on time and was exactly what he wanted!Can’t go wrong with Costa Del MarEl modelo es el Tuna Alley. El modelo 63mm es version OMNIFIT viene en talla XL, el soporte de la nariz es mas pronunciado que los modelos convencionales.El marco carey es brillante y el azul de las micas no es tan azul como en otros modelos.Revise algunos puntos de seguridad que me proporcino la marca y todo en orden asi que confio en que son originales.Otra cosa que me comentaron los representantes de COSTA via mail es que los fabrican en China e Italia. Hay modelos totalmente fabricados y ensamblados en edtos paises y modelos ensamblados en USA Aunque en su pagina dicen ser ensamblados a mano en USA esta no es totalmente cierto.Hasta ahorita solo los he usado lal manejar y para salir a caminar. En cuanto los prube en el agua les cuento.Actualizacion. En el Agua funcionan de maravilla.No te arrepentiras de comprarlos.Los que compre fueron vendidos y enviados por Amazon México y provienen de Italia.Siempre uso costa del mar tuna alley pero este no me gustó ya que vino en omnifit y yo utilizo el ajuste normal y este no me quedo. El pad de nariz viene ajustable.
