The Details

The Giro Synthe MIPS II Helmet has impressive safety features with a slim design to match. Cool and comfortable, the Synthe is a great value addition to your riding kit.

The Synthe MIPS II features the Roc Loc 5 Air MIPS fit system with 2-way fit tuning to allow you to get the most comfortable and secure fit. Couple this with the integrated MIPS brain protection system which protects against 'rotational violence' caused by angled impacts. In addition, there are Aero Mesh Panels with a dedicated port for securely docking sunglasses as you ride.

This second generation Synthe is light and more comfortable than before. The compact design simply carves through the air and thanks to the improvements made in the second generation, the Synthe will continue to be a fan favourite.

  • Integrated MIPS brain protection system
  • Roc Loc 5 Air MIPS fit system
  • Ionic+™ anti-microbial padding

Our Verdict

An icon of the road cycling scene, the latest Giro Synthe MIPS II is well-known for being a lightweight, comfortable and most importantly a super safe helmet ideal for all kinds of riders.
