Easily adjusted with adjustable cotton Velcro, it fits the baby's head and stays comfortable as the baby grows without squeezing the developing skull. Exclusive Double Safety PeaksThe nearly 10mm built-in padded double peak design on the forehead of our Baby Head Protector adds additional safety cushioning and upgrades the forehead hazards of traditional helmets. Parents can rest assured that this helmet can be used for their babies, ensuring that every step of their exploration is carried out in safe care.Breathable Suspended Air DesignThe unique suspended air design is equipped with airways and air holes to promote airflow, keep the baby's head cool, and minimize trapped body heat. Even in hot weather, the baby's head can stay comfortable and dry. Lightweight and ComfortableThe Ultra-light design of less than 0.22 pounds ensures that your baby will not feel any burden when wearing it. The soft and comfortable material provides all-round head protection for your baby, especially for those babies who are unsteady on their feet and are just beginning to explore the independent world. High-Density Shock-Absorbing FoamOur Baby Head Protector is made of high-density thickened shock-absorbing foam material. The thick foam material can provide excellent protection for the baby and effectively reduce the possible injuries caused by falls or collisions during the baby's crawling or walking process.
