Bather Swim Trunks Technical Surf 28 XS Men’s Blue

Bather surf trunks I bought in 2017. They don’t currently sell this style so I included a picture of the style in a different color. They are the surf trunk without the mesh netting. Pretty good condition except they have a small discoloured circle on the bum (pictured). Maybe bleach not sure. Bather Swim Trunks Technical Surf 28 XS Men’s Blue.
