I don't know much about surfing, but saw one of those Olympic surfing clips making the rounds, and was surprised to see some of the surfers wearing helmets. It makes sense, given the massive force of nature surfers are up against, and we now have a better understanding of concussions than when surfing was invented. That said, I've learned not all surfers wear them. "Even top pro surfers can have a wipeout that changes their life forever. But when it comes to wearing a helmet, surfers are still torn," says pro surfer Griffin Colapinto.

Colapinto is sponsored by Oakley, who has been working on a helmet that they reckon surfers will want to wear.

Their description of the design illuminates the user resistance points they're trying to overcome:

"The best-in-class helmet is made from strong ABS and is designed to absorb impact, disperse energy, and reduce blunt force trauma. Its unique shell design prevents disorientation and drag in the water and with open ventilation, surfers can easily maneuver through and under water even while duck diving, allowing for immediate drainage upon reaching the surface."

"Complete with adjustable and removable ear protection, engineered to maintain hearing, prevent cuts and protect against eardrum blowouts, the helmet allows surfers to stay aware of their surroundings, make split-second decisions, and always be in control."

The helmet is called the WTR Icon, and you won't see it at this year's Olympics; it won't be ready for production until November of this year.
