Giro Women's Source MTB Helmet (MIPS)

Rugged and trail-shredding ready, the Women's Source MTB Helmet, with MIPS, has a lot going on when it comes to keeping you safely protected. When you're ejected off your bike rather unexpectedly, the deep design offers excellent all-round head coverage, keeping your head safe whichever way you fall. The full-wrap In-Mould polycarbonate shell offers a rugged and durable finish and this is paired to an impact-absorbing EPS liner for superb safety. Integrated into the helmet is also the brain-protecting Multi-directional Impact Protection System (MIPS).

What is MIPS?

Multi-directional Impact Protection System (MIPS) is a proven system that reduces the rotational forces on the brain when you're involved in a crash. The forces are absorbed and redirected to prevent them from being transmitted to the brain. 

MIPS is a Brain Protection System

Rotational motion can cause brain injuries

The low friction layer allows a sliding movement of 10–15 mm, in all directions, reducing rotational motion to the brain during impact

Roc Loc® 5 Fit System

For easy adjustment, you'll enjoy the benefits of the Roc Loc® 5 Fit System. This provides an unmatched level of comfort, stability, adjustability, and weight savings. You can easily dial-in both fit tension and adjust vertical position with a single hand. Just twist the dial for a tighter feel on rough terrain, then back it off a notch and relax across the flats or a warm climb. Even with these remarkable features, Roc Loc 5 is still nearly 40% lighter than its popular predecessor, Roc Loc 4.

Trail Ready Comfort

Once you're up to speed and in the flow of the trail, you'll appreciate the excellent ventilation on offer. A total of 17 vents and internal channels combine to give a rush of cooling airflow over the top of your head. Coolfit™ padding is also a key feature, offering instant comfort, excellent sweat-wicking and anti-microbial qualities to prevent an itchy head after a hot mountain bike session. Lastly, the moto-stye screw-in visor keeps your eyes shielded from the sun and kicked up trail debris.
