Lazer Revolution FF MIPS bicycle helmet The Revolution FF bicycle helmet from Lazer is a revolution among mountain bike helmets. The helmet is made of fiberglass, making it virtually indestructible. This material also ensures that the helmet guarantees safety. In addition to being safe, the helmet is also very comfortable. The helmet contains the Advanced Turnfit ATS system. With a simple turn of the knob you can adjust the size of the helmet so that you can adapt it to the circumference of your head. The visor of the helmet is adjustable and offers a very wide field of vision. The MIPS system is an intermediate layer that is located between the fiberglass exterior and the padding and is equipped with elastic attachments. Thanks to the MIPS system, the helmet can move in relation to the head in the event of a fall, which ensures that rotational forces can be better absorbed. With a normal helmet, the impact is only absorbed by an impression of the fiberglass. An excellent helmet for the experienced mountain biker.
