Review on Optimized Giro Synthe Road Cycling Helmet for Adults by Martin Alvarez

The helmet I received was an old version of the Giro Synthe. The main difference is in the straps, specifically the little key that connects the two straps under the ear. This original model has a plain buckle, while newer models have a preset buckle built into the plastic in a "Y" shape, which is a better design. Despite the reduced price, I am very happy with my purchase. Synthesis is a known commodity. It's light, aerodynamic and well ventilated, even in the 100+ degree humid heat that I ride in every week.
