Them im guessing you'll need XL or XXL. What size F1s do you wear. The Mares seem slightly smaller than F1 equivalent. The Regular Power Plana is fractionally smaller than the Regular F1. I'm not sure about bigger sizes.
I don't have F1's yet. I was planning on getting a set later this year if/when I pick up a dry suit, but the Power Plana could be possible candidate. I would never use or buy Jet's (or Rockets) again. I put too many hours on them in the Military and absolutely hated them.
If I remember correctly, I could fit in XL jets if I was wearing a neo boot or Chuck-T's.
