Fox Clothing Speedframe Pro Blocked Mips MTB Mountain Cycling Helmet

Top of that list is MIPS™, which is designed to reduce rotational motion and redirect forces away from your brain should you crash. Dual-density Varizorb™ EPS bumps up that impact protection even further by spreading forces of impact across a wider area. The 360-degree fit system and Fidlock® SNAP helmet buckle ensure a perfect fit every time you ride, and the buckle is a cinch to operate, even with gloves on. The XT2® liner is antimicrobial and manages odor while wicking moisture away from the head, and once it gets a little stinky, is easily removed and washed.
Goggles pair well with the Speedframe Pro Blocked Helmet too, thanks to the 3-position adjustable visor. If you’re looking for a performance-minded trail helmet, congratulations—you just found your new lid.

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.
