Just like the Cookie M3 the G4 is an impact rated skydive helmet and therefore one of the safest helmets in skydiving

The G4 complies to the newly developed Skydiving Helmet Standard XP S 72-600. This standard requires the design of the helmet to comply with a list of technical requirements. Below is an abbreviated list of the XP S 72-600 technical requirements. The Cookie M3 and G4 conform to this standard under EU Regulation 2016/425.

Please find below the Helmet Sizing Chart.

There are six different helmet sizes available in three shell sizes creating the most comfortable fitting helmet on the market.

Using a tape measure please determine the circumference of head to the nearest centimeter or 1/8 of an inch. Do this by placing the tape measure around the widest part of your head which will be above the eye brows and ears.

‘K Leef recommends to actually try on a G4 prior ordering for accurate sizing.
