Lazer Tonic bicycle helmet The Tonic bicycle helmet from Lazer is an ideal helmet for the novice cyclist. The helmet has a very distinctive design and color. The In-Mold construction keeps the weight low, while comfort remains high. The back of the helmet contains a TS+ Turnfit system. With this dial you can easily adjust the close-fitting but comfortable fit of the helmet. This way you can adjust the fit of the helmet at all times. The MIPS system is an intermediate layer that is located between the EPS lining and the padding and is equipped with elastic attachments. Thanks to the MIPS system, the helmet can move relative 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 a depression of the EPS lining. To keep your head cool on hot days, the helmet contains 28 ventilation openings, which make the entry of cooling air flows very easy. With the Tonic bicycle helmet you are ready for your adventure!
