I'm looking for a used Semi Dry suit. I had a Mares Isotherm years ago and sold it, a goof, and would like another one. Other brands OK but I don't want a really thick one like 8 mil. I'm 6 foot 1 and 170 with slim legs and arms. A medium tall or maybe a medium or small cut large size. Need not be perfect, but have another 75-100 dives left would be fine. Thanks!
