becomes hard in extreme cold???

This helmet becomes hard and its size shrinks by temperature between 5° and 1° to such an extent that I thought I bought the wrong size but once warm at home it becomes soft again. bad component? however it is approved for -10°. I've had this experience several times in front of witnesses, it's amazing...

Very useful

Protects you from impacts. It is not a total protector but it lessens the blow and at least those classic blows protect you

too bad he had everything to please

looking for a flexible helmet for surfing I thought I had found my happiness only from the first session, the rear part of the helmet irritated me at the level of the adjustable part... Same for the attachment part under the chin, the fabric part supposed to protect the blow of the plastic strap does not stay in place. results: I had to get out of the water to take off the helmet because it was so uncomfortable.

Very good

Good value for money

Nice and nice helmet

Excellent price / quality ratio. On the other hand, do not trust what the site announces in terms of size. I took M because announced a head circumference between 56 and 59 (I am 58) and the helmet is too small, mark and pain on the forehead. I will give it back and take L. The yellow color is really nice and can be seen from afar. Info: I use it for wake boarding.

insufficient protection when foiling

Unfortunately, the protection against board contact (fast foil board) is not sufficient. The following foilboard left a big dent a few cm above the ear.

Additional Product Information


Shell: 80.0% Foamed Thermoplastic Polyurethane, 20.0% Polyamide ; Flap: 100.0% 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 -10°C, above 50°C).

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 recreational surf sessions in normal conditions, but not for motorised sports or surfing in very large waves.The test protocol is valid for recreational surfing only. As such, its use in any other water sport ( foil, wake, kite, etc.) is at the user's own risk.


S (head circumference 52-54 cm)M (head circumference 55-57 cm)L (head circumference 58-64 cm)XL (head circumference 60-64 cm)The sizes given are for guidance, as the helmet is soft. So some may prefer to have it tighter than others.The label attached to the helmet is designed for hard shell helmets, the head size tolerance is lower in this label.
