Thanks again to the customer service boss, this helmet has significantly improved the balance of power, especially the suspension type to solve the pressure of the eye socket. The omni-directional wrapping feeling, especially the covering feeling behind the pillow, can evenly spread the gravity in the front of the helmet to the back. The knob to change the size at the back is much more convenient than the original elastic band, and it is said to be better than the original design.Generally speaking, it is comfortable.
