The Synthe II MIPS is an icon of road helmet design, combining the performance advantages of a compact profile with great cooling power and luxurious comfort for road and gravel riders.

The Synthe MIPS Helmet offers good looks in a slim design while offering more coverage on the back of the helmet for a little extra assurance. The compact form of the Synthe MIPS slips through the air with ease across multiple yaw and head angles and offers impressive cooling power. Key features include the Roc Loc Air fit system with 2-way fit tuning and Aero Mesh Panels with a dedicated port for securely docking sunglasses as you ride. The Synthe MIPS also has the Multi-Directional Impact Protection System, which we believe can redirect energy and provide more protection in certain impacts.
