Additional Info
The Coanda Core is built specifically for surf. It's designed to handle surf-specific impacts — like collisions with boards, fins, or the reef — while staying secure in heavy water. It's lightweight, drains quickly, and doesn't mess with your balance or hearing. What really sets it apart is its use of the Coanda Effect — a design principle that guides water flow smoothly around the helmet to reduce drag. This makes duck dives easier, reduces turbulence, and helps you move more efficiently through the water.
Certified for Impact Protection
It meets the EN 1385 water sports safety standard — the same certification used for whitewater and wake helmets. We’ve gone further by optimizing the helmet for the unique challenges of surfing: quick duck-dives, hold-downs, and high-speed wipeouts.

Stays On In Big Waves
When choosing the correct size, the helmet is secure in all conditions— from thumping days in crowded lineups at your local break to heavy reef sessions on your Indo trip. It stays put when you need it most.
Hearing and Balance
The Coanda helmets are designed with acoustically tuned ear vents that let sound through while still protecting you from pressure and surfers' ear — so you stay aware, balanced, and protected.
Comfortable Enough For Long Sessions
The internal padding is soft, low-profile, and dries fast. It's antimicrobial too — no funk. Most surfers forget they're wearing it after just a couple of waves.
Eco-Friendly
They're working toward a lighter footprint — using solvent-free adhesives, recyclable materials where possible, and sustainable packaging. This is just the beginning.
Product Care
Just rinse with fresh water after each session, then let it air dry in the shade. Avoid leaving it in a hot car or direct sun for long periods.
