Giro's high-end road racing helmet is the Aeon, pronounced 'A-on' and defined as 'a type of divine entity'. You'll see it throughout the peloton thanks to its industry leading weight and ventilation. Perfect for riders who value a light, but secure and comfortable helmet which sacrifices nothing.

Key Features:

  • Cutting edge design and materials produce a helmet that is light, comfortable, secure and well ventilated.
  • Thermoformed SL roll cage is both secure and 49% lighter than the roll cage used in the Giro Ionos.
  • 24 vents combined with deep internal channels make this one of, if not the, best venting helmets around, helping to keep you comfortable.
  • RocLoc5 system, the latest from Giro offers a secure fit which is comfortable and easy to adjust.
  • Microtech Tri-Locs and ultra-light slim webbing are both comfortable and light.
  • X-Static padding is plush and light, as well as anti-bacterial thanks to the silver yarns used, this helps keep the helmet smelling fresh.
  • Certified to CE EN1078
  • Weight: 225g (PBK Office Scales for a Large)
  • Includes: Extra X-Static pads and owners manual. Giro Crash Replacement Program:
  • Anyone with a Giro helmet up to three years old that was purchased from a UK dealer can replace it at a reduced price if it has been involved in an accident.

Helmets that are sold on Probikekit.com are certified with a European CE EN1078 standard. This is a European standard and although the helmet is perfectly safe to use, specific countries may have their own certification which is legally required if you intend to wear the helmet recreationally or in a competitive racing environment. If you are unsure, please check your specific country requirements and check with the manufacturer to see if the helmet has received any additional certification.
