O'Neill swim top, long sleeve UPF 50. I have never worn and still has tags. I have had this in my closet awhile. There is a warning on the inside of the shirt that states that the protection may be reduced by getting wet, stretching or with use ( the second picture from the end). Please see pictures. If you have any questions or would like more details, please do not hesitate to ask. Non smoking home. We do have a dog. I will drop off for shipping next day, Monday through Saturday, in the morning. If you purchase on Saturday or Sunday, I will ship on Monday (If the post office is closed for a holiday, I will ship the following day). I welcome all reasonable offers, I will either accept or I will respond back with my best offer. Thank you for looking!
