Nice medium protective helmet

It’s a good helmet for surfing but the forehead get a bit irritated from the line of the helmets design in that area. Also the chin strap needs a bit more protection for your chin. It’s a good medium protective helmet.


Thanks for reviewing our product.

Regarding the forehead line issue you mentionned, it might be from a sizing issue.

Our size chart is posted on the product page. If the size is wrong, you can reach out to our CS for an exchange.

Noted for the chin straps, we will improve the padding thanks to your feedback.

For anyone looking for possibly the best solution for a soft helmet for surfing, this is it. Unbelievably comfortable, fits like a glove and does not inhibit your vision. Duck diving is not an issue with the water flowing away nicely. It’s so comfortable it’s like it’s not there. I’m probably going to buy another one in case I ever miss placed this one, it’s that good. Super light and incredibly well made. There isn’t really anything else in the market that I have tried or seen that even compares.

Safety while surfing

I had a bilateral fracture at C6 when I was dumped some months back so I was looking for some protection when I resumed surfing. This looked to offer what I was looking for at a reasonable price. From cycling, I know how these should fit to be effective. Based on my measurements a medium should suit and it did. But a large be more comfortable for prolonged sessions in the water and still work well. I have not been able to wet test it yet because the wind and waves have not been cooperating here in Perth. I will add to this review if I can when I do. I am part of a large group of older surfers and we bought these in a batch of four to defray the shipping costs. It is possible that more people in the group may opt to use helmets come the summer.

Bought for surf kayak

Not used yet but appears good protection over much of the head. Sizes seem small so it’s worth checking before buying if possible.

OK fit, but could be improved a lot

The helmet is OK regards fit etc. However, the chin strap really makes my neck sore, to the point it's unwearable. Strap needs to be made of a smoother material or have a glide skin cover over the strap, like you get on the collars of higher end wetsuits. Also, I bought this helmet for the peak to keep the sun out of my eyes, it's really too small to do this. Furthermore, the ear covers aren't really effective and allows wind water to enter too easily. Would be better to have a layer of lycra, a diaphragm, over the holes to protect the ear canal better. IMO you're better off paying more for one of the established brands.

Size not as described online

I ordered one of these as the website said that the XL would fit heads up to 64cm. When it arrived, the product label said that XL was only from 60-61cm . It might be a nice helmet, but it doesn't appear to be the size they say it is, and having tried it on, I strongly suspect the size on the product label is correct

Größenangaben in der Beschreibung stimmen nicht

Der Helm ist leicht, ist wesentlich angenehmer zu tragen als die üblichen Kitehelme. Die Größenangaben in der Beschreibung stimmen allerdinsg nicht. Ich habe Kopfumfang 56cm und nach diesen Angaben bräuchte ich Größe L. Die diese Größe ausverkauft war, habe ich kurzerhand Größe M bestellt. Am Etikett steht allerdings dass Größe M für Kopfumfang 56-57cm ist und der Helm passt mir wie angegossen.

Cómodo para olas pequeñas

Es muy cómodo, pero tiene un pero, en olas medianas o grandes, la visera, coge agua en los revolcones y te mueve la cabeza , pienso que pudiendo hacer daño inclusive en el cuello. Pero por lo demás es excelente.

raspa en el cuello

Le he tenido que coser un trozo de neopreno en la zona de la nuca, por que el elastico que trae le hacia un roce bastante doloroso, a mi hijo. Si se pudiera terminar mejor el casco por esa zona, para que no rozara, seria ideal.

Las tallas no son correctas!

He recibido el casco y esta super guay! Muy ligera y de buena calidad para el precio que tiene! Pero las tallas no están bien! Tengo la cabeza de 53cm y según la guia debería coger talla M, pero elegí la talla S porque siempre llevo cascos de talla S. Cuando recibí el producto, vi que la talla S corresponde a 54-55cm y no a 51-52cm como pone la descripción. Aun asi, Me queda perfecto porque se puede ajustar atras.

Additional Product Information



  • 20% Polyamide
  • 80% Foamed thermoplastic polyurethane (tpu)


  • 100% Polypropylene


This product limits the surfer’s injuries such as scalp wounds and impacts that cause superficial effects. No protective equipment can offer total protection from injury. The effectiveness of the protection can be reduced as a result of extended exposure to extreme temperatures (below 14°F, above 122°F).

Recommendations for use

Wearing this protection should not stop you from respecting the safety guidelines and priority rules associated with surfing. For maximum protection, the helmet should be adjusted to the user’s head with the help of the support system in the chin and neck area. Try different sizes in order to select one that best matches the size of your head.


This helmet can be used during water sports in normal conditions except for motorized sports and surfing sports in very large waves.
