Mountain biking is a demanding sport, so compromises and cutbacks on equipment are not a good idea. The 4Forty is designed to withstand the rigors of life on the trail: with generous ventilation, the comfort of the Float Fit adjustment system and Sweat Guide, extensive coverage at the back of the head, an adjustable visor, and integrated MIPS. With this equipment, comfort, and protection, the 4Forty can compete with helmets that cost twice as much.
