Full-face helmets in Gear and Rigging September 12, 2019 · Edited September 12, 2019 by pchapman 56 minutes ago, evh said: So... this "certification" is not even valid for skydiving? Don't get your certifications mixed up. The poster you quoted was quoting one sample airports helmet standard. The G4 helmet is certified to the French AFNOR "Skydiving and Wind Tunnel Helmet Standard XP S 72-600" The Tonfly TFX for example is certified to that same standard, plus EN966: 2012 + A1: 2012, category HPG for AIRBORNE SPORTS I'm not sure why you would be all against a hang-gliding/paragliding/microlight airsports standard -- unless you came up with some very specific technical objections based on actual facts. (Hooknswoop provided a link to some EN966 info) EDIT: Standards can be frustrating because one can't always download the actual standard (without paying a lot of money for them). More searching on the web would be needed to help understand how XP S 72-600 compares with other prior standards, what things are emphasized or not.
