Giro Fixture MIPS II Women’s Helmet — Features & Details
The Giro Fixture is the world’s best-selling mountain bike helmet — a title it’s held by consistently delivering more than riders expect at the price. This new Fixture MIPS II Women’s carries that tradition forward with a properly updated design: a revised silhouette, redesigned MIPS® integration, improved ventilation, and a women’s-specific shell — all at £89.99.
If you want a trustworthy, well-specced MIPS helmet that fits a women’s head properly and won’t break the bank, this is one of the strongest options on the market.
Redesigned MIPS® Brain Protection
MIPS (Multi-directional Impact Protection System) is a slip-plane technology designed to help reduce rotational forces on the brain during angled impacts — the kind most commonly experienced in real-world crashes. On this updated Fixture MIPS II, Giro has redesigned how MIPS is integrated into the helmet, combining the slip plane directly with the Roc Loc® Sport fit system. The result is protection that feels more natural and comfortable to wear, without any compromise on performance.
Women’s-Specific Fit
The Fixture MIPS II Women’s uses a shell developed specifically for women’s head shapes rather than simply scaling down the unisex version. The Universal Woman sizing covers 50–57 cm and is engineered to suit a wide range of women’s head shapes straight out of the box. Combine that with the Roc Loc® Sport dial and you’ve got a helmet that fits properly from the first ride.
Revised Design & Improved Cooling
This is a genuinely updated helmet, not just a new colourway. The reworked shell profile improves airflow compared to the previous generation, channelling more fresh air over your head on climbs and warmer days. The revised silhouette also sits cleaner and lower, giving better forehead coverage without feeling bulky.
In-Mould Construction
In-mould construction permanently fuses the polycarbonate outer shell with the EPS foam impact liner — creating a helmet that’s lighter, more ventilated, and more durable than traditional hard-shell designs. There are no weak seams or joins, just one solid, well-integrated structure.
Roc Loc® Sport Fit System
Giro’s Roc Loc® Sport system is one of the best fit mechanisms available at this price. A single dial at the rear gives a 7cm adjustment range with a precise, satisfying click that tells you exactly where you are. It’s fully ponytail-compatible, operates with one hand, and holds its position reliably once set.
Quick-Dry Padding & Reflective Details
The internal padding wicks sweat efficiently and dries quickly, keeping things comfortable over longer efforts. Reflective rear decals improve visibility in low-light conditions — a practical touch for early mornings, evening rides, or the kind of overcast days the New Forest does so well.
Who Is It For?
The new Giro Fixture MIPS II Women’s is ideal for female mountain bikers, trail riders, and gravel cyclists who want a properly specced MIPS helmet with a fit designed for them, not adapted from a unisex version. It’s a brilliant everyday helmet and a great step up for anyone currently riding without MIPS protection. For a women’s option without MIPS at a slightly lower price, take a look at our Giro Fixture II Women’s at £69.99.
