## Long description

Protective bicycle helmet 100 КНИГ Aircraft Composite black size XL is a hard-shell cycling helmet designed for urban and recreational use. The helmet uses composite materials in its outer shell and impact-absorbing liner to reduce forces transmitted to the head in case of impact. It includes an adjustable retention system, multiple ventilation openings and removable internal padding for a tailored fit and everyday comfort during rides and short commutes.
Advantages
The composite shell construction provides a balance of strength and weight, helping to deliver reliable impact protection while keeping the helmet manageable for daily wear. The adjustable fit system and removable padding allow quick size and comfort adjustments. Integrated ventilation channels promote airflow to reduce heat buildup. The black finish offers a neutral appearance compatible with a variety of cycling apparel and accessories.
Suitable for
 Urban commuting and short city rides
 Recreational cycling and weekend outings
 Leisure trips and short-distance bicycle errands
Key specifications
 Material: composite outer shell with impact-absorbing inner liner
 Color: black
 Size: XL with adjustable retention system
 Ventilation: multiple air vents with internal airflow channels
 Comfort: removable and washable internal padding
How to use
Place the helmet on your head so that it sits level and covers the forehead. Adjust the retention system at the rear and tighten the chin strap so it fits snugly but comfortably; straps should form a V under each ear. Check that the helmet does not tilt forward or backward and that it remains stable while you move your head. Replace the helmet after any significant impact or if the shell or liner shows visible damage.
Usage recommendations
Inspect the helmet regularly for signs of wear, clean removable padding according to care instructions, and store the helmet away from direct sunlight and extreme temperatures to preserve the composite materials and fit system.
