One is Evelyn Swim Cloche style, and the other is Reversible Surf Bucket Hat style.
Both hats have the L/XL tags still on them. I would like any potential buyer to know: I usually wear a L/XL with Coolibar hats (I have 4 others), and these are both too small for me. I would consider these both to be a size Small. Perhaps the fact that they're for sailing means that they're expected to be tight? I don't know. What I do know is that I can't wear them, because they're too small for me.
I'm not sure the best way to provide measurements, since the hats are floppy and stretchy. I measure 7.24 inches across / diameter.
