Bicycle cap Rockbros YPP037 Black summer design — cycling cap, lightweight breathable

Rockbros YPP037 is a lightweight summer under-helmet bicycle cap in black designed to be worn under cycling helmets. It provides UPF50+ protection from UV rays, features cutouts to accommodate glasses, includes reflective elements for better visibility, and is made from breathable, skin-friendly ice silk that absorbs sweat while maintaining comfort during warm-weather rides.

Advantages

The cap delivers high UV protection (UPF50+), a soft elastic fabric that wicks moisture and allows airflow, and integrated cutouts that stabilise glasses during fast riding. Reflective details on the forehead, goggle openings and the rear strip improve visibility in low light conditions. Its universal fit covers head circumferences from 54 to 72 cm and weighs approximately 20 g, keeping the helmet fit unaffected.

Suitable for

• Training rides and sportive cycling
• Commuting in sunny or warm weather
• Recreational and long-distance cycling tours

How to use

Place the cap on the head so the forehead reflective logo and goggle cutouts align correctly with your glasses and helmet.

After riding, rinse or hand-wash the cap according to fabric care instructions and let it air-dry.

Recommendations

Use the cap during sunny or hot conditions to reduce sun exposure and manage sweat. Ensure the cap does not interfere with helmet straps or positioning; if the helmet feels unstable, readjust the cap or remove it to restore correct helmet fit.
