General Specifications
About the Product
The Synthe™ is the pinnacle of road helmet design, combining the performance gains of an aerodynamic profile and light weight with great cooling power to enhance rider comfort and efficiency in road rides and races. The compact form slips through the air with ease across multiple yaw and head angles, and offers greater cooling power than the Aeon.™
Our first Air Attack™ was a revelation in styling and performance for all types of riding—from track to triathlon, road and mountain biking to cyclocross. Inspired by the original, the new generation Air Attack™ fine-tunes the design for a lightweight, compact and extremely efficient aerodynamic shape that slices through air.

What customers say about "Key Specs"
Giro Synthe Helmet, Matte Black, Medium
  • Really happy with this helmet. Bought it for the weight and looks (as in it's a fairly normal looking bike helmet, not hardcore aero or race looking). Overall, the helmet is light enough that it's possible to forget you're wearing it and surprising very comfortable considering the minimal padding.
  • I am 59ish and medium fits perfect but almost no room for a hat or liner when cold.
  • Feels like a top end product i had an accident in this helmet and it saved me from serious head injury
  • Looks fantastic, really light weight, very comfortable and my head remained cool even on tough 100 mile route recently.

Giro Air Attack Helmet
  • Nice light, attractive helmet for commuting use.
  • I am very pleased with this purchase thus far. I bought this helmet for triathlon use.
  • This is a very light and a durable helmet. Also the design of this helmet is very nice compared to the conventional road bike helmet.
  • Fits great. I have used it in several triathlons this year.
  • I dropped the helmet a few times but the shell is very durable and it holds well with scratches.

What customers say about "Features"
Giro Synthe Helmet, Matte Black, Medium
  • Very Light and fits great. Great quality.
  • Love it, great helmet and fits my small head perfect!
  • Love the design but you'd expect a little better quality for this steep price. The straps feel really cheap too. In the end, it's very light and aero.
  • Light, comfortable, easily adjustable and good looking.
  • While it is super light, breaths very well and stays put it is pretty minimal for padding.
Giro Air Attack Helmet
  • Its comfortable and gets plenty of airflow even on hot summer days.
  • I have a small head. So I looked up the measurements and was on the very top end of the measurements for the small size. I ordered it and it fit just fine.
  • I ride in AZ in 85+ degree weather regularly, and have no issues with the venting.
  • Comfortable fit, good range of adjustment for cold weather hat, long hair, short hair, etc.
  • I think the main concern of the helmet is ventilation and there's enough even on very hot days.
