Bell 4Forty Air MIPS Sprint Vintage Olive MTB Helmet

Equipped with pro-level technology but designed with the privateer in mind, the Bell 4Forty Air Mips is the first choice for your next trail helmet.

The Bell 4Forty Air MIPS Sprint delivers pro-grade protection without the pro-level price tag. Built for riders who demand performance on every trail, this helmet combines cutting-edge safety technology with practical comfort features that keep you riding longer. Advanced MIPS Evolve® technology reduces rotational forces from impacts, while extended hard-shell coverage protects where it matters most. The Float Fit™ system and Ionic+™ padding work together to manage sweat and maintain comfort through long sessions. The 3-position adjustable visor adapts to sun, rain, or goggle use, and the Fidlock® magnetic buckle makes getting in and out effortless. Ventilation is optimized throughout—the redesigned shell channels air flow while the Sweat Guide™ pad keeps moisture away from your eyes and face. Eyewear storage notches and a goggle gripper keep your gear secure, while premium straps and No-Twist Tri-Glides™ stay put no matter how technical the terrain gets. Lightweight at 360g (size M) and certified to CE EN1078, the 4Forty Air MIPS is engineered for daily trail riding where reliability and comfort are non-negotiable.

• MIPS® EVOLVE — Mips Evolve is 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.
• FLOAT FIT™ — A minimalist, lightweight fit system with an easy-to-turn rubber overmolded dial for adjustments (integrated with Mips®).

• NO-TWIST TRI-GLIDES™ — Quick-adjust fasteners that help keep straps flat and properly positioned
• SWEAT GUIDE™ — Sweat Guide pad design pulls moisture away from the brow pad and away from eyewear.
• IONIC+™ PADDING — Quick-drying interior padding helps manage sweat while fighting odor-causing bacteria.
• 3-POSITION ADJUSTABLE VISOR — 3-position adjustable visor allows for sun protection and integrates easily with goggles or glasses.
• GOGGLE GRIPPER — Rubber grip on the back of the helmet keeps your goggle strap in place.
