## Long description

The Bicycle Helmet 100 КНИГ Aircraft Composite in yellow, size XL is a cycling helmet constructed from composite materials to provide head protection for riders with extra-large head sizes. Designed for road, urban and recreational cycling, the helmet combines a standard outer shell with internal lining and an adjustable fit system to secure the helmet during rides while maintaining comfort and coverage.
Advantages
This helmet offers reinforced protection through composite construction, delivering impact resistance while keeping the shell profile compact. The internal lining provides cushioning and sweat absorption, and the adjustable fit system enables a tailored fit for XL head sizes to reduce movement during activity. The yellow color increases visibility in traffic and mixed-use environments without compromising the helmet’s structural features.
Suitable for
Road cycling
Urban commuting
Recreational and fitness rides
Riders with extra-large head sizes (XL)
Key specifications
Material: composite shell construction with internal protective lining
Size: XL, designed to fit extra-large head circumference
Color: yellow for improved visibility
Fit system: adjustable retention mechanism for a secure fit
Design: standard helmet shell shape suitable for cycling
How to use
Place the helmet on the head so the front edge sits just above the eyebrows, then fasten the chin strap and adjust the retention system until the helmet feels snug but comfortable. Ensure the helmet does not tilt excessively forward or backward and that side straps form a V-shape just below the ears. Before each ride, check that the shell and lining are intact and that adjustment components move freely; replace the helmet if it has sustained significant impact or shows visible damage.
Usage recommendations
For optimal protection, replace the helmet after a major impact or every few years depending on wear. Clean the internal lining with mild soap and water, avoid strong chemicals, and store the helmet in a dry place away from direct sunlight to preserve materials and color.
