Children's helmet Martes Mimsy Jr size XS 44–48 cm for cycling, rollerblading and skateboarding

Martes Mimsy Jr size XS (44–48 cm) is a children's protective helmet designed for cycling, rollerblading and skateboarding. The helmet is intended for young users with smaller head circumferences and provides basic impact protection during everyday outdoor activities, learning-to-ride sessions and casual action sports. Its compact size and adjustable fit allow it to be worn comfortably by children while they develop balance and coordination.

Advantages

The helmet combines a lightweight shell with an impact-absorbing liner to reduce the force transferred to the head during minor collisions. An adjustable retention system and padded interior ensure a snug fit across the 44–48 cm size range, helping to maintain correct positioning during movement. Ventilation openings support airflow to reduce overheating during active use, and easy-to-use fastening makes putting the helmet on and taking it off quick for both children and caregivers.

• Children learning to ride a bicycle
• Recreational rollerblading and inline skating
• Skateboarding in parks and driveways
• Everyday outdoor play and short urban trips

Key specifications

How to use

Place the helmet level on the child's head so the front edge sits just above the eyebrows. Adjust the retention system until the helmet is snug but not uncomfortably tight; the helmet should not move excessively when the child shakes their head. Fasten and adjust the chin strap so that two fingers fit between the strap and the chin, ensuring a secure closure. Inspect the helmet before each use for visible damage and replace it if any cracks or severe impacts are present.

Usage recommendations

Use the Martes Mimsy Jr helmet for supervised riding and recreational activities that require basic head protection. Replace the helmet after a significant impact, after several years of regular use, or if padding and straps show signs of deterioration. Follow local safety guidelines for children's protective equipment and pair the helmet with appropriate protective gear such as knee and elbow pads when rollerblading or skateboarding.
