Island Bum Nautical Flag Swim Trunks

Each pair of our swim trunks are made from 90% recycled (plastic bottle) polyester & 10% spandex. They are 4 way stretch, UPF protection, quick drying, eco friendly, have a 6" inseam, and feature a fine mesh lining, which makes them super comfortable. Being an Island Bum we live in our swim trunks, so we wanted to make sure they were comfortable and took our time testing them to make sure they held up, and that you would love them. I think you just found your new favorite swim trunk. 

Design features the nautical letters "I" & "B" in the maritime signal flags in Navy Blue and White.
