The only question we get  asked more than what is UPF+50 is what the heck is 1640 - and it's a good question - Well here's the Story back in the year 1640 a group of Pilgrims from Connecticut set out and went Sailing/ they became lost possibly due to the use of adult beverages and when finding Land they ended up discovering Southampton thus the 1640 founder's date - So if you buy one of our Southampton Sun Block 1640 S Hoods you have a great story to tell - and, of course, you are protected from Windy Days and Ultraviolet Radiation by our wonderful Microfiber UPF+50 garment technology - Two wins for you!!
