What's the quality of the giant's helmet? Is it up to standard?

The giant's helmet is of good quality and meets the national standards. You can consider the giant G99 helmet, which is suitable for Asian head type and adopts an integrated molding process. At the same time, MIPS technology is supported to effectively slow down the rotational impact of external forces on the brain. The 19 hole air guide groove adopts the vertical layout of the current mainstream, which strengthens the air flow to form an air duct to quickly take away the hot and humid air in the head, keeping the head dry, ventilated and radiating.
