## Long description

The BELL 4Forty Air Integrated MIPS mountain bike helmet in matte black camo, size M (55–59 cm), is designed for trail and enduro riding where protection, ventilation and on-trail stability are required. This helmet combines integrated MIPS rotational impact protection with a multi-zone ventilation layout and an adjustable retention system to provide a balanced solution for day-long rides. The shell profile and internal padding are configured to give coverage appropriate for aggressive trail use while keeping weight and airflow in mind.
Advantages
This helmet integrates MIPS technology to reduce rotational forces during certain impacts, while the multi-zone venting improves airflow to help manage heat during sustained efforts. The adjustable fit system offers quick and secure on-trail adjustments for a stable fit and the matte black camo finish provides a low-glare, understated appearance. Internal comfort padding and a trim shell help maintain a balance between protection, weight and breathability for extended use.
Suitable for
Trail riding and enduro stages where impact protection and ventilation are priorities
Full-day rides that require stable fit and heat management
Riders seeking integrated rotational-impact protection without a bulky design
Key specifications
Fit range: medium size fitting heads approximately 55–59 cm
Integrated rotational protection system for mitigation of rotational forces
Multi-zone ventilation pattern for directed airflow and heat dissipation
Adjustable retention system for on-the-fly fit tuning and stability
Low-profile shell with internal comfort padding for extended-wear comfort
How to use
Place the helmet on the head so that it sits level and covers the forehead without tilting backward or forward. Adjust the retention system until the helmet feels secure but not overly tight, and connect and position the chin strap so it sits comfortably under the chin with enough room to insert one or two fingers between strap and jaw. Ensure vent openings are unobstructed to allow airflow. Inspect the helmet before each ride for signs of damage or wear and replace it if it has been involved in a significant impact.
Usage recommendations
Use this helmet for trail and enduro riding where a balance of ventilation, comfort and integrated rotational protection is required. Replace the helmet after a hard impact, follow the manufacturer’s care instructions for cleaning, and pair with properly adjusted goggles or glasses for optimal eye protection and ventilation management.
