This is a premium road biking helmet with a semi-aero design. Class-leading comfort and adjustability make it a standout in a sea of high-end products. Solid overall scores in every rating metric add up and leave the Synthe firmly at the top. It is the winner of our Editors' Choice Award and our favorite all-around helmet for training and racing use.
The Synthe MIPS received some new since our testing in early 2017. Giro confirmed that no other changes were made to this helmet as of fall 2018.
