Protection you can depend on, session after session. Our helmets are made with precision-tuned Expanded Polypropylene foam. This type of foam is made to absorb repeated water and reef impacts—after impact, it bounces back into place.

Knock helmets are certified to EN 1385; 2012 and CE marked (NB 0598). We've also received a four-star rating from Virginia Tech Helmet Labs—making the Knock helmet one of the safest surf helmets you can buy.

Our open water system reduces drag and neck strain by allowing water to move through the helmet smoothly. Plus, our precisely moulded channels are designed to move water away from your eyes and face.

For our helmet liners, we use a mix of premium EVA and PU foams. These materials mold to your head's shape and provide extra impact cushioning—plus, they don't absorb water.
