Who It's For

• Surfers who want leg coverage but hate arm restriction in warmer months

• Warm-climate surfers who still want a bit of core and leg warmth

Sizing

Sizes run S, MS, M, MT, LS, L, XLS, XL, XXL. The base letter is your chest/girth; the S/T suffix adjusts for height (S = shorter, T = taller) at that chest. At 2mm it's a mild-to-warm-water suit — a rough guide of roughly 18–22°C — warmer than a short-arm spring thanks to the full legs, but not a cold-water suit. Entry is via chest zip. Aim for a snug, second-skin fit with no loose spots at the lower back or ankles that would let water flush through. Sizing follows O'Neill's official men's chart — match your height, weight and chest to your size code and you're sorted.
