I'm not a fan of Icaro line of helmets, iirc Dan Keyser was wearing one the day he had his accident. To make matters worse, the Iguana/Skin helmets are listed as "bargain end helmets" on the Icaro website. Great.
Here are a couple of quotes I've taken from their website concerning them:
"Iguana, the exclusive Italian fashion, but...
You have to handle this helmet with great care.
If you put the helmet in your bakpack, don't sit on it
Hold the helmet on the chin strap, not at the adjustable wheel
Don't fold the ear protectors; handle the visor with care."
and:
"Our helmets were designed and built specifically to be as light as possible. However they optimize safety for hang glider and paraglider pilots, as shown by the information above. "
As if that weren't bad enough, they make these shells as "one-size-fits-all." The correct fit is achieved by turning an adjustment wheel that tightens a band around your head. Where have I seen that before?
That's the exact same thing that's used in welding helmets!

These are probably suitable for stumbling around in a drunken stupor, but not flying.
The moment you doubt whether you can fly, you cease forever to be able to do it.- J.M. Barrie, Peter Pan
