    • Giro Women's Seyen Helmet (MIPS) 2019

  • Giro Women’s Montara MTB Helmet (MIPS)

    Carrying over many of the best protection technologies from Giro’s legendary road range, the Women’s Montara MTB Helmet gives you all the confidence you need to own the trail. Key to its success is the use of the patented MIPS system that keeps your head stable in the event of a crash. Additionally, the solid polycarbonate shell does a great job of holding the helmet together in a collision, and you get a great secure fit thanks to the easy-to-adjust Roc-Loc® 5 Air fit system. Elsewhere in the helmet, featherweight webbing and a Slimine™ buckle are soft and gentle against the skin, 25 Wind Tunnel vents keep lots of cool air moving, and anti-microbial padding ensures you stay feeling fresh.

    Roc-Loc® 5 Air fit system

    Holding it all together, alongside the MIPS system outlined below, is the industry-leading Roc-Loc® 5 Air fit system. Combining comfort and stability for your head without adding any extra weight to your ride, it keeps close to your skull for unbeatable security, with an easily adjustable fit that can be dialled quickly and easily using only one hand.
