Why We Like The Giro Synthe MIPS II Helmet

The Synthe created an undeniable allure when it first hit the peloton, with riders like Marianne Vos so powerfully and elegantly dominating races while wearing the streamlined and form-fitted design. It was an unmistakable presence that somehow found a flattering way to be a vented cycling helmet, and the new Giro Synthe MIPS II will undoubtedly carry that heritage for many miles to come. The updates to the new generation are subtle yet significant. Gone are the separate MIPS and Roc Loc systems, which operate on a more integrated platform to enhance both fit and comfort. And gone are the aero-mesh vent coverings in favor of an open port for increased airflow through the now 19 vent ports and inner channels.


The goal of the Synthe MIPS II is to provide you with a lightweight, more ventilated, and safer riding experience, whether going all-in on a gravel epic into rarer country or if you’re lining up for the championships at a course you’ve ridden dozens of times. And competitively priced below the new Helios Spherical and Aether Spherical, the updated classic packs enhanced value into a race-ready package.

Runs Large

Familiarity:
I've used it several times
Size Bought:
Large

Have bought Giro's since 2003. Have always bought Large, they have always fit. This is too big, even tightened down all the way. It falls forward and knocks my glasses down my nose. My hat size is 7 1/8 to 7 1/4. Unless you wear larger than a 7 1/4, check this out closely as might need to return.

I returned this product before using it

I bought this helmet to replace my current aging helmet. I was disappointed to see the “new” helmet is almost 3 years old. This is being returned.

On my third one, switched from black to white, and crashed once. Fits perfect, size small. I love that it holds the sunglasses!
