The Bell 4Forty Mips is a trail helmet for everyday mountain biking, with extended rear coverage and an adjustable fit. Its Mips Evolve system is designed to help reduce rotational forces from certain impacts, while the Float Fit dial makes it easy to adjust the helmet around your head.
Bell has paid attention to the details you notice on a longer ride. Sweat Guide directs moisture away from your brow and eyewear, the rear goggle gripper helps keep a strap in place, and the adjustable visor makes room for goggle storage. No-Twist Tri-Glides help the straps sit flat.
