Bell 4Forty MIPS Mountain Bike Helmet

Mountain biking is a demanding sport and leaves little room for compromise when it comes to equipment. The 4Forty is designed to best withstand the rigors of a lifetime on the trail. Generous ventilation, a comfortable float fit, built-in sweat guide, extended rear head protection, full hardshell design, the adjustable visor and the added protection of MIPS set this helmet apart. Other models that have comparable protection, comfort and versatile features often cost twice as much. The 4Forty is a lightweight that easily rivals the heavyweights in the industry.

Features:

1. Fusion In-Molding Polycarbonate Shell
   A process pioneered by Bell bonds the helmet's outer shell to the EPS foam liner to create a sturdier helmet.
2. MIPS Equipped and Float Fit (integrated with MIPS)
   MIPS stands for Multi-directional Impact Protection System, which is a leading slip-plane technology inside the helmet designed to reduce rotational forces that can result from certain impacts. A minimalist, lightweight fit system with an easy-to-turn rubber overmolded dial for adjustments (integrated with MIPS).
3. No-Twist Tri-Glides and Sweat Guide
   Quick-adjust fasteners that help keep straps flat and properly positioned. Sweat Guide pad design pulls moisture away from the brow pad and away from eyewear
4. Goggle Guide Adjustable Visor System
   Adaptable visor system accommodates both goggles and glasses and works with or without the visor attached.
