Product Description

The Giro Hex Mountain biking helmet features rugged style, big performance and impressive value. Features the new Roc Loc 5 fit system. After more than ten years of refinement, this ground-breaking fit system provides an entirely unique use experience with an unmatched level of comfort, stability, adjustability and weight savings. With Roc Loc 5, 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 tough 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 40-percent lighter than its popular predecessor, Roc Loc 4. Roc Loc 5 systems is: 1) Micro Dial. The heart of the Roc Loc 5 is this ratcheting, micro-adjusting dial. A simple, two-finger twist of the Micro Dial opens or closes the retention system and each click is audible. 2) Three-Position Vertical Fit - It's never been easier to change vertical positions and fine-tune fit. We incorporated a three-position bracket that features 15-millimeters of precise up/down movement. Like the Micro Dial, this system can be adjusted without removing the helmet. 3) Carefully crafted ergonomic arms are shaped to be as comfortable as possible, yet work flawlessly with Giro eyewear (what we call Super Fit engineering). 4) Dual Pods - These two panels are designed to firmly grasp the back of your head while comfortably cradling the occipital lobe. Strap management - with Roc Loc 5, your helmet straps are woven through the fit system, so they are always in the perfect position. Complex Internal Design - Dozens of small parts work together seamlessly to provide exceptionally user-friendly adjustment. Minimal and Light, yet Strong - Although this fit system is 40% lighter than its predecessor, it's much stronger. In testing, Roc Loc 5 performs flawlessly, even after 6,600 cycles (equivalent to 3 years of riding with 3 round trips per day).

Customer Reviews

This helmet fits well, is comfortable, and well ventilated.
Chris Allen
With all the air vent, it keeps my head cool from this East Coast humidity.
Dynamix
I've found that the Giro helmets fit my head better than any other brand.

Been a fan of Giro helmets for awhile. Have used multiple Giro helmets for my road cycling and wanted a dedicated helmet for mountain biking. With the new Roc Loc 5 system offered on this helmet I jumped at it and am very pleased with the results. Roc Loc 5 is a huge improvement over Roc Loc 4 and I feel its the best strap system available today. Helmet size Medium fits great for my head. Plenty of ventilation. Great price for a Giro quality helmet.

Color Name: Matte ChalkSize Name: Medium
Pros:

Air ventilation is truly excellent, fit is snug and comfortable, feels very light, the visor does not chatter in the wind, the helmet's design is fairly stylish.

Cons:

The straps often need to be pushed away from the back of my ears, the rubber part of "overmolded arm" on the RocLoc system inside the helmet interferes with the back tips of my glasses.

The helmet is used mainly for my daily commute. The RocLoc system makes the helmet fit well but at the expense of not being able to wear sunglasses comfortably. I wanted to try the Giro brand after I wore out my excellent Bell X-Ray helmet. When this Giro Hex wears out I will replace it with a new Bell X-Ray.

I really like this helmet, tons of air flow and looks pretty cool. The Roc Loc 5 system is really solid and hugs my head perfectly. With a couple clicks the helmet is perfectly snug and won't fall off of my head even if the straps aren't on (although obviously you should use the straps).

In response to the sizing issue, I used the little print out and tape together measuring tool at Giro's site. Worked fine for me, fits perfect. It is definitely a fitted helmet though; it is too small for my Dad's head. But I like the whole fitted feel much better.

The helmet fits well. Make sure to check your head size before purchasing. They seem to run a little smaller than previous Giro helmets I have bought.

I bought this helmet because my old helmet almost made me pass-out after a few strenuous trail runs in the Florida heat. I had read other reviews (on MTBR) where people had claimed that this helmet had excellent air flow. They were correct. You can actually feel the air flowing through the deep grooves in the underside of the helmet. The helmet is light, and has extra protection for the lower part of the back of your head. It is also comfortable and looks great in the matte-black color.

Seems like a good helmet, it's a good brand. I like the adjustable visor. Only complaint is with the inside of the helmet, at the very top & center, it pokes into my head very uncomfortably. I put one of the included foam pads in there and it seemed to do the trick.
