We believe that children should be encouraged to participate in organized sports and to participate in a family and/or community sport. Youth athletes should be taught the fundamentals of safe, fun and fair competition and be given an opportunity to be supported and connect with the rest of their family through the sport they love. So Bike Helmet is also very important for us to do such job.
The vents help and speed cooling down of the head. The more the vents are set, the greater the reduction in sweat, but it also makes the helmet hot. Since the vents allow air to blow in to the outer layer of the helmet and the inner frame keeping in the cool air is necessary for a durable helmet.
