Smith Optics Forefront 3 Mips MTB Cycling Helmet













From flowy single track to technical descents, the Smith Forefront 3 Mountain Bike Helmet has your back (and front and sides) more than ever thanks to a complete internal injected roll cage, extended back coverage and a Mips® Safety System that's integrated directly into the helmet padding for more comfort. Add venting that increases airflow by 25 percent, a micro-adjustable BOA® Fit System and complete KOROYD® coverage, and you have a helmet that's as comfortable as it is loaded with cutting-edge design and impact protection. And when you start to sweat as you climb or prepare to drop in on a descent, you can count on the 20 vents plus our AirEvac™ ventilation to keep your sunglasses or goggles fog-free. The visor adjusts for easy goggle storage between laps, and you can slide your sunglasses into the shell for secure storage on the front or back.

How to measure
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.

Once you know the circumference of your head, see the available sizes shown on the product and select the appropriate one.
The majority of cycling helmets have some form of adjustment for size, usually in the form of a ratchet adjuster to tighten or loosen the straps, some helmets will also come with different thickness pads to further customise the fit.
