Paragliding without a helmet...not a good idea. It’s not only about landings when you need to protect your head, it’s also important for botched takeoffs and canyon walls that get a little too close a little too fast. Plus they’re well ventilated but can still keep your head warmer (and the hair out of your face) when you're flying the high winds..
Ozone nutshell helmets are made specifically for paragliding, to allow you maximum visibility while still keeping your noggin protected during a crash. Please note that the chin guard is sold separately.
