One of the most exciting property of the Harsh HX1 is that its weight can be only the half of other ABS shell helmets which makes it a very comfortable wear. Most of the time helmets are made of an ABS shell and EBS layer lining. With the overmold technology the EPS padding is injected into the shell so it makes a very durable and lightweight material. The HARSH helmets also having the most strict CPSC certificates for sure. The simple and sleek design and shaping protects the back-lower side of the head too and the vents provide enough airflow to keep your head cool.
