Sizing

Sizes run S, M, MS, MT, L, LS, XL, XLS, XXL, 3XL. O'Neill's base letter is chest/girth; the S/T suffix adjusts for height (S = shorter, T = taller) at that chest. At 2mm it's a warm-water suit — a rough guide of around 19°C and up. Unlike the chest-zip Hyper suits, this one is a back zip: you open the full back, step in, and pull the leash cord up. A back zip is the easiest entry system going, though it can let in a touch more water than a chest zip at the neck — so a snug fit with no gaps at the collar, lower back and cuffs matters. Sizing follows O'Neill's official men's chart — match your height, weight and chest to your size code and you're sorted.
