## Long description

Protective bicycle helmet 100 КНИГ Aircraft Composite in navy blue, size XL, offers head protection for road, city and recreational cycling. The helmet features a composite shell construction engineered to absorb impact energy and reduce the force transmitted to the head. Integrated ventilation openings support airflow to help regulate temperature during rides, while an adjustable retention system ensures a secure fit for larger head sizes.
Advantages
The composite shell combines strength and controlled deformation to provide effective impact management without excessive bulk. The adjustable retention system allows fine tuning of the fit to minimise movement during cycling. Ventilation openings are positioned to encourage airflow through the helmet, helping to reduce heat buildup on warmer days. The XL sizing accommodates larger head circumferences and improves comfort for users who require a roomier fit.
Suitable for
 Road cycling where robust impact protection and a stable fit are required
 City commuting and urban riding with moderate speeds and frequent stops
 Recreational cycling, including longer leisure rides where ventilation and comfort matter
Key specifications
 Construction: composite shell designed to absorb and redistribute impact energy
 Size: XL (suitable for larger head circumferences)
 Color: navy blue
 Fit system: adjustable retention mechanism for secure positioning
 Ventilation: multiple airflow openings to assist heat dissipation
 Intended use: road, city and recreational cycling
How to use
Place the helmet on the head so it sits level and covers the forehead without tilting backward. Adjust the retention system until the helmet feels snug but comfortable, and fasten the chin strap so it sits under the jaw with enough tension to hold the helmet in place while allowing normal jaw movement. Before each ride, check that the helmet is free from visible damage and that straps and buckles are secure. Replace the helmet after any significant impact or when signs of structural damage appear.
Usage recommendations
For optimal protection, ensure the helmet fits correctly and is adjusted before every ride. Clean the shell and liners with mild soap and water, avoid solvents or abrasive cleaners, and store the helmet away from direct sunlight and extreme temperatures to preserve materials and performance.
