Giro Merit Spherical Womens Dirt MTB Mountain Cycling Helmet
The Merit™ Spherical W is a high-performance trail riding helmet built around the ball-and-socket design of Spherical Technology™ to provide amazing ventilation, deep coverage and luxurious comfort.
Helmets with Spherical Technology offer more comprehensive performance and protection with the combination of a Mips® brain protection system to redirect rotational impact energy.
Plus separate inner and outer liners featuring Progressive Layering™ help manage high and low-speed impacts.
The massive Wind Tunnel vents are combined with channels in the EPS foam liner, creating amazing airflow through the helmet to exhaust heat out, even on long, hot climbs.
Fit and stability adjustments are fast and easy with the Roc Loc® Trail Air fit system, and plush Ionic+™ padding provides exceptional sweat absorption while combating odor with permanent anti-microbial performance.
With all of these features, it’s an ideal choice for fast, flowy trail riding and hard pedalling.

Giro Women's 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 56cm then a size M (55-59cm) or a One Size (50-57cm) will fit you.
