Giro Chronicle Mips MTB Cycling Helmet
- HARDSHELL WITH IN-MOLD HARDBODY™ LOWER WRAP — The two-piece shell combines a tough outer hard shell with a polycarbonate lower shell permanently fused to the liner for durability without excess weight.
- INTEGRATED MIPS® BRAIN PROTECTION SYSTEM — All Giro helmets are designed to reduce as much energy as possible while meeting and exceeding stringent safety standards. The goal of Giro's Mips-equipped helmets is to reduce rotational forces. Giro believes that helmets equipped with this technology can reduce the amount of rotational force that may be transferred to rider's brain in certain impacts.
- P.O.V. PLUS™ VISOR — Our P.O.V. Plus™ visor features an adjustment mechanism that lets you move the visor up and down in indexed steps. These steps include three riding positions plus a high position for goggle storage above your brow. The design allows you to easily adjust your visor with one hand while riding.
- ROC LOC® 5 FIT SYSTEM — The industry benchmark in comfort; stability; adjustability and weight savings. In addition to enhancing the fit and comfort of helmets; Roc Loc® 5 allows you to easily custom tune the fit tension and the fore-aft tilt of the helmet in seconds using a single hand. And it's lighter than comparable systems too; making it the ultimate in skull-hugging luxury.
- WIND TUNNEL VENTILATION — Giro helmets are developed utilizing our proprietary Wind Tunnel™ ventilation system. This elaborate design combines active vents in the helmet's shell with exhaust channels inside the helmet that thrust fresh; cool air over and around the rider's head while forcing heat and stale air out. It's the most effective cooling system available; and a difference you can feel every time you ride.
Occasionally, without notice, manufacturers change product design and/or specifications.
Giro Helmet Size Guide
How to measure your head size
To find the circumference of your head, place a tape measure in the centre of your forehead, wrap it around above your ears and around the back of your head. If there's a slight difference between two different sizes, always go for the tighter size.
Giro cycling helmets are adjustable so will fit a range of head sizes. Once you know the circumference of your head, select an appropriate helmet size. For example, if your measurement is 57cm then a size M (55-59cm) or a One Size (54-61cm) will fit you.
