An updated classic. Already one of our most popular trail helmets of all time, the 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 II is outfitted with IONIC+ padding with permanent antimicrobial 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 your run is done. A clever breakaway interface for your favorite light or camera is included, too.

Note: We recommend you try helmets on before buying. Make sure the helmet fits with a little room when the fit system is loose, and sits low enough to protect your forehead without hindering your vision. Once you’ve got the right size, you can adjust the fit.
