Giro Montaro II MIPS Womens Mountain Bike Helmet in White
An updated classic. Already one of our most popular trail helmets of all time, the women’s Montaro™ Mips® II now benefits from the Roc Loc® 5 Air Mips System.
This sleek design integrates 2-way fit and stability adjustment with the Mips brain protection system, for an added measure of protection from rotational forces without excess plastic against your skin. The helmet’s compact shape offers deep coverage and an in-mold hardbody shell for enhanced durability without excess weight.
In addition to advanced brain protection, the Montaro Mips II W is outfitted with Ionic+™ padding with permanent anti-microbial performance plus 16 vents with internal channeling to keep you cool and comfortable.
We also built in all of the features you need for great fit with goggles, including strap grippers on the back of the helmet and our patented P.O.V. Plus™ visor that allows you to lift the visor and place your goggles on the front of the helmet when the run is done.
A clever breakaway interface for your favorite light or camera is included too.
