The Super Air is the first trail helmet to offer Flex Spherical + MIPS, making it our most advanced trail helmet. Period. This combination of outstanding safety, optimized ventilation and extreme lightness brings epic achievements within reach — on any trail, in any terrain. When you’re ready to step up, upgrade by adding the optional chin bar. See you on the trail! - 18 vents, 4 brow ports - Overbrow ventilation features intake ports on the brow of the helmet to usher in cool air and push it through the air-channel matrix for full-head ventilation - Compliance: CPSC bicycle - Flex spherical + MIPS - comprehensive energy management - flex spherical enhances our ability to address high-speed impacts, low-speed impacts, as well as rotational impacts. Think of it as comprehensive protection, with the added bonus of being able to design better helmet ventilation. - Construction: Fusion in-mold polycarbonate shell - a process pioneered by Bell bonds the helmet's outer shell to the EPS foam liner to create a sturdier helmet. - Progressive layering: the process of engineering a helmet liner with variable EPS foam densities to better manage the transfer of energies after some impacts - Fit System: Float fit - a minimalist, lightweight fit system with an easy-to-turn rubber overmolded dial for adjustments (integrated with MIPS) - Interior: Sweat guide pad design pulls moisture away from the brow pad and away from eyewear

Mountain biking is a demanding sport — compromises and shortcuts when it comes to gear are never a good idea. The 4Forty is built to withstand the rigors of a trail-riding life with generous ventilation, the comfort of Float Fit and built-in Sweat Guide, extended rear coverage, a full hard shell, adjustable visor and integrated MIPS protection. Boasting the comfort, protection and broadly capable features of helmets costing twice as much, the 4Forty is a bantamweight, all-conditions, all-kinds-of-trail champion packing a heavyweight value. Specs - 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. - Construction: Fusion in-mold polycarbonate shell - a process pioneered by Bell bonds the helmet's outer shell to the EPS foam liner to create a sturdier helmet. - Goggle-guide adjustable visor: accommodates both goggles and glasses - Number of vents: 15 - Interior/liner type: Sweat guide pad design pulls moisture away from the brow pad and away from eyewear - Fit system: Float Fit - a minimalist, lightweight fit system with an easy-to-turn rubber overmolded dial for adjustments (integrated with MIPS)

It is widely regarded that increased visibility equates to increased safety. To that end, we have taken our classy all-rounder, the Formula, and incorporated a bright, 20-lumen rear LED into the fit system. It’s unobtrusive, highly visible, easily rechargeable with an included micro USB, and it just might make the difference between being seen and not. Specs - MIPS (Multi-directional Impact Protection System) - a leading slip-plane technology designed to reduce rotational forces that can result from certain impacts. By integrating the MIPS slip plane into the retention system, we are able to reduce complexity and weight for a compact, better ventilated helmet that fits more closely to the head. - Lithium battery packaged: In product - Number of batteries: 1 - Batteries included - Chemical composition: Stainless steel lithium - Construction: Fusion in-mold polycarbonate shell - a process pioneered by Bell bonds the helmet's outer shell to the EPS foam liner to create a sturdier helmet. - Lithium battery energy content watt hours: 0.576wh - Battery type: Lithium ion - Number of vents: 19 - Interior/liner type: Sweat guide pad design pulls moisture away from the brow pad and away from eyewear - Fit system: Float Fit LED - a lightweight fit system with an easy-to-turn rubber overmolded dial for adjustments (integrated with MIPS) - Weight 285 grams (size M) - Small = 52 – 56cm - Medium = 55 – 59cm - Large = 58 – 62cm
