I have had Superior add and remove some dry suit material as I have gained and lost weight over the years. It is amazing what he can do with a simple video of you wearing the suit. You can’t go wrong with Mark and Julie when you need adjustments. Gamble saw one of his alterations and said it was better than the factory could do.I had a DUI measured at DEMA years ago by Bob Stinton -- the guy who developed the telescoping torso idea -- and it fit terribly. Too short in the arms, too big in the waist and baggy in the legs. I evenutally paid Superior Drysuit Repair to have it fixed.
Ironically an off the shelf low end DUI suit -- CNSE -- fits me great and dives like a wetsuit, streamlined, warm, stretchy. YMMV.
