The middle thickness, and the broadest mission profile. 5.5mm covers what the others can't reach in a single suit — hours-in-the-water work in temperate seas, long surface intervals, the cold-shoulder-season dive where 3.5mm runs out of warmth in the second hour and 7.5mm is unnecessary heft. Hooded jacket over high-waist trousers, double magnetic Fidlock closure clips on the beavertail. Charcoal Titanium Dioxide internal coating, Supertex fabric on the seat, waist, and knee panels, knife pocket with Fidlock Snap buckle on the right thigh, glue-reinforced stitching at the elbows, chestpad, and whistle pocket. Designed and tested in Hawaii.

Aloha Jake, stoked to hear the Tropicam is treating you well. That 5.5mm really does lock in the warmth without feeling like a straightjacket. Enjoy the water.
