The O'Neill Ninja 1.5mm Hood is a thin, lightweight surf hood designed for cool-water sessions and wind protection — a no-fuss head covering that keeps your ears and scalp comfortable without the bulk or restriction of a full cold-water hood.

Key Features:

• 1.5mm Neoprene — ultra-thin construction suited for water temperatures in the 60–68°F range; provides wind and spray protection for cool but not cold conditions
• Stretch Construction — flexible neoprene moves with your head through duck dives and turns without pulling or restricting neck movement
• Snug Face Opening — close-fitting face seal blocks cold wind at the jawline and forehead perimeter, which is the primary comfort benefit of a thin hood in mild conditions
• Sealed Seams — glued and blindstitched seam construction prevents water infiltration at the seam lines for consistent thermal performance
• Low-Profile Fit — sits flat under a helmet and layers under a wetsuit collar without adding awkward bulk at the neck

The O'Neill Ninja line offers reliable cold-water protection at a more accessible price point than the Psycho Tech series. At 1.5mm, the Ninja Hood is the seasonal transition piece — it's what you grab when the wind is cold and your ears are taking a beating, but the water isn't cold enough to justify a full 3mm hood. It's also useful as a standalone ear protection piece paired with a springsuit in windy conditions.

Sizing & Fit: Size by head circumference. Hood should fit snugly without creating pressure points. If between sizes, size up.

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