You’ve seen this Giro Synthe from the outside before.  It’s Giro’s fastest-ever and coolest-ever road helmet, and a design that is changing the game.  The Giro Synthe Mips helmet advances what you find inside the helmet and above the noggin with the Multi-direction Impact Protection System.

Mips is a new technology that is being deployed in more helmets every year.  The basic idea is that the helmet can move around, just a little, when secured to your head, so when your casque-covered noggin collides with some heavy object, like the ground, your head can rotate a little to reduce rotational forces on your head and reduce overall impact.  It achieves this by lining the EPS foam with a “sliding enabler” material and then creating an internal structure called the “Mips Low Friction Liner” which goes around the RocLoc Air and allows the helmet to move while being secured to your head.  The Liner itself is extensively cut out, mimicking the helmet vents to keep cooling and comfort the same.  All this adds only 20 grams to the total helmet weight.
The Giro Synthe helmet design does aero road better. The name comes from synthesis: in this case, synthesizing the aero performance of Giro’s Air Attack and the cooling performance of Giro’s Aeon. Basically, the Synthe does both better.

The aero performance is improved over the Air Attack in the “heads up” position common to riding in a pack. The cooling performance is better than the Aeon. In fact, the Synthe is the coolest helmet Giro has ever tested on their Therminator headform. It’s almost as good as a bare head.
The aero and cooling performance are tied together. The shape is far more compact than the Aeon, with the fewer, larger vents, nineteen in total, leading to larger internal channels. And to help promote airflow, Giro uses their RocLoc Air secondary retention system to actually keep the helmet off the head. By doing this, airflow is improved around the face and through the internal channels to the exhaust vents.
Helping keep the helmet in place is the primary retention system, which utilizes Featherweight webbing for straps, a slimline chin buckle, and lightweight, adjustable camlock buckles under the ears. Where your head contacts the RocLoc, X-Static padding contacts the skin and wicks away the sweat.
Cognizant of cyclists desire to have a home for sunglasses on the helmet, they’ve created dedicated ports for sunglass temples to easily get inserted and removed. No tricks, no wiggling, just off your eyes and into the helmet, and vice versa. They are integrated into mesh panels which themselves are drag-reducing features of the helmet.
There’s another benefit to improved aerodynamics. A quieter ride experience. By reducing the turbulence around your head and helmet, the ride will seem not as noisy. You might even find yourself talking in a lower voice because you don’t have to overcome so much noisy air.
The package put together is sixteen percent faster than the Giro Aeon. It possesses eight grams less drag than the Giro Air Attack in when the head is 30-degrees from vertical. It has two percent greater cooling than the Aeon. It’s thirteen percent lighter than the Air Attack. The official weight is 270g for a Medium, but we’ve seen them come in a good bit less.
The Giro Synthe Mips is not only more aero than aero helmets, cooler than cool, and lighter than light.  It is safer, thanks to an innovative new impact-reducing liner system.
