The Synthe MIPS II Helmet by Giro - High protection on the road with MIPS

Giro's Synthe MIPS II road bike helmet is even better ventilated than its predecessor. One aspect responsible for this is the Roc Loc Air System, with which you also adjust the helmet's size. The combination of an In-Mold shell and SL Roll Cage ensures low weight and stability. Additional impact protection is provided by the MIPS system. The streamlined design is a big plus for fast rides.

In-Mold Construction
The polycarbonate outer shell is glued to the EPS inner shell, which increases the resistance of the helmet. It also makes it easier to shape vents, which means that In-Mold designs typically have better ventilation systems and a lighter weight.

MIPS stands for " Multi Directional Impact Protection System" and refers to a movable protection layer consisting of three components: an EPS liner and low-friction liner, which are then connected by an elastomeric fastening system. This layer protects the brain from oblique impact. The principle of the natural low-friction layer of the brain is adapted in order to minimise the forces that occur.

Roc Loc Air
The size is adjusted in small steps with just two fingers. The ventilation of the helmet has been optimized. The helmet design creates an air cushion between the head and the helmet shell. This allows the airstream to flow without resistance and cool the head.

Thermoformed SL Roll Cage
The Thermoformed SL Roll Cage is a reinforcement made of polycarbonate. It is 49% lighter than reinforcements in common helmets. It is also possible to use a 15% less compressed EPS foam, which contributes to the weight reduction. A high level of safety is maintained.

Incorporated silver threads have an antibacterial effect, which prevents the formation of odours. In addition, the silver threads have cooling properties when warm and warming properties when cold.

Sehr leichter Helm. Beim Lackieren wurde etwas geschlampt. Der Rot-Schwarz-Übergang verläuft neben der Geometrie.

Genialer Helm, für mich super schönes Design und top Verarbeitung mit angenehmem Haltesystem. Eine Brillengarage ist integriert jedoch etwas fummelig aufgrund des MIPS.
Komme vom sehr guten Atmos 1u.2 für den nach jahrelanger Nutzung jetzt mal ein Upgrade anstand. Der Synthe ist so leicht, de merkt man nach dem Aufsetzen nicht mehr, absolut genial.
Zudem merkt man das die Entwicklung nicht stehen bleibt, der Der Helm umhüllt den Kopf und sitz nicht oben drauf, was ein sehr sicheres Gefühl vermittelt.
Für mich jeden Cent wert.
