## Long description

RockBros TT-32004 Shark is a children's bike helmet in size M (54–58 cm) with a detachable chin guard that adds lower-face protection. The helmet is designed for everyday cycling and recreational riding, combining head protection with the option to convert to a traditional open-face helmet. It features multiple ventilation openings and adjustable straps to ensure a secure, comfortable fit for growing riders.
Advantages
The detachable chin guard allows quick conversion between full-face style protection and a lighter, open configuration without tools. Adjustable retention and chin straps provide a reliable, customized fit that helps keep the helmet stable during use. Ventilation openings improve airflow to reduce heat buildup during activity, while the helmet's molded shell and impact-absorbing liner are engineered to manage energy from impacts.
Suitable for
 Daily commuting and school rides for children
 Leisure cycling and park riding
 Family bike outings where added face protection is preferred
 Kids learning to ride or practicing basic off-road skills

 Chin guard: detachable for optional lower-face protection
 Ventilation: multiple vents for airflow
 Retention: adjustable straps for secure fit

How to use
Place the helmet on the child's head so the front rim sits just above the eyebrows. Fasten and adjust the chin strap until it is snug but comfortable, allowing one or two fingers to fit between the strap and the chin. Use the retention system to fine-tune the fit around the head so the helmet sits level and does not tilt forward or backward. To attach or remove the chin guard, follow the manufacturer's mounting points: align the guard with the helmet's connector points and click into place or press release mechanisms to detach. Inspect the helmet for secure fastening before every ride.
Usage recommendations
Inspect the helmet regularly for visible damage and replace it after any significant impact. Choose the M size for head circumferences within the indicated range and adjust straps for a secure fit. Clean the helmet with mild soap and water and avoid exposure to high heat or solvents that could degrade materials.
