Sizing

This is a jacket (top only), sized on simple alpha sizing — XS, S, M, L, XL, XXL, 3XL — no short/tall split. At 1.5mm it's a warm-water layer for roughly 20°C and up (rough guide), worn over boardshorts or under/over a suit for a little extra core warmth; flatlock seams mean it's built for comfort and stretch rather than full cold-water sealing. As with any neoprene top, you want it snug through the torso and arms — loose neoprene flushes and drags in the water. Match your usual top/chest size — it maps to O'Neill's official men's chart. Zipperless pullover design — no zip to fail or leak.
