The O'Neill Psycho 1.5mm Surf Hood keeps your head and ears comfortable in cool to mild water — a thin, stretch hood built from O'Neill's Psycho-line neoprene that provides wind and water protection without the bulk or claustrophobia of a full cold-water hood.

Key Features:

• 1.5mm Neoprene — ultra-thin construction provides just enough insulation for cool-water sessions (60–68°F) and wind protection without overheating; worn alone or under a helmet
• Psycho-Line Neoprene — O'Neill's high-stretch neoprene delivers excellent mobility; the hood moves with your head naturally without restricting neck range of motion
• Snug Face Seal — contoured face opening seals against the jawline and forehead to block cold water and wind at the face perimeter
• Low-Profile Design — designed to layer under a wetsuit collar or wear standalone; sits flat under a helmet without adding uncomfortable bulk
• Glued and Blindstitched Seams — sealed seams prevent water entry at stitch lines; important even at 1.5mm where seam flushing causes rapid heat loss

Ear protection matters more than most surfers realize — wind and cold water hitting exposed ears session after session accelerates exostosis development and causes significant discomfort in cool conditions. A 1.5mm hood like the Psycho is the warm-weather version: enough coverage to keep your ears and head comfortable when the wind is cold and the water is in the mid-60s, without making you sweat during a long session.

Sizing & Fit: Order based on head circumference. The hood should fit snugly with no dead space but without restricting breathing or causing headaches. If between sizes, size up.

Care: Rinse thoroughly with fresh water after every session. Hang to dry in shade. Do not machine wash or tumble dry.
