Full face helmets are designed to offer extra protection in higher-risk events such as downhill and freeride. They vary from ultra-lightweight designs that simply offer additional protection from branches to heavy Moto-Cross style helmets designed to protect the whole head in a more serious fall. All helmets sold at Fatbirds meet BS EN 1078:1997 standards, which is identical to the EU standard, and which replaced BS 6863:1989 in 1997
