MJ @ SI posted this on SI SWIM IG last week...this looks a lot like Isabell. Coincidentally, Isabell deleted her IG account. I could never figure out why IMG hasn't done more with her. Her two little sisters are both active models as well. I'm sure this was taken at a well-known local surf spot in Hawaii, you can see the outer reef break in background. If it's not Isabell, I'm thinking it may be Nina A.
