Giro Saros Helmet -

To us, the hallmark of a Giro design are its three central vents. And, not coincidentally, you'll find this feature on the Giro Saros Helmet. It was originally part of the Prolight design, but nearly every subsequent helmet has revolved around the three prominent central holes. To us, this trident conveys stability and balance. And while Giro builds on older designs, it never adds baroque touches, instead opting for little practical flourishes. So, in this tradition, the Saros helmet hearkens to the long-gone days of the Eclipse, while moving forward into the contemporary.

With the Saros, you receive trickle-down technology like the Roc Loc 5 --Giro's easiest to use and most comfortable retention system to date. Also used in Giro's top-of-the-line Aeon helmet, Roc Loc 5 adds more adjustability, while removing 40% of the weight from its prior iteration. So, what's different? For starters, the indexed Micro Dial on the back lets you adjust the tension to perfection with a two fingered twist. It's really that simple. Additionally, the Three Position Bracket allows 15mm of vertical adjustment in the retention basket -- enough to comfortably fit any head shape. But, what's comfort without ease of use? Giro facilitates quick donning of your casque with clever strap management. The retention basket has strap holders to ensure that they'll be right where you want them by the time the helmet falls into place.

For protection (that is what a helmet does, right?), the Saros features an in-molded polycarbonate shell that, when combined with the expanded polystyrene liner, creates a structural skeleton that's abrasion-resistant for any high speed slides across the pavement. Giro has also ensured that it aids in the absorption of any direct high-speed impacts. And going a step even further, the Saros also has Giro's Roll Cage technology. Don't worry about looking for it -- you'll never see it. It's a net of tough nylon that's been molded into the foam liner of the helmet. Basically, this 'web' keeps the helmet from breaking apart like a rotten ice chest when you have a bad crash. The Saros has 23 Wind Tunnel vents to channel airflow directly to your head in order to keep you as cool as possible, regardless of high temperatures.

The Giro Saros Helmet is available in the sizes Small Small (51-55cm), Medium (55-59cm), and Large (59-63cm) and in the colors Black/red, Black/blue, Matte Black, Matte Black/yellow Livestrong, Matte Titanium, and White/silver.


  • Roc Loc 5 adjustable retention system on the Giro Saros bike helmet makes adjusting fit and position an easy effort; loosen or tighten with a simple twist
  • Roc Loc 5 fit system lets you easily dial-in both fit tension and adjust vertical position with a single hand


  • In-mold construction fuses a tough polycarbonate outer shell with the helmet’s impact-absorbing foam liner
  • Roll Cage reinforcement of tough DuPont Nylon for extra strength and integrity

Support and Cushioning:

  • A sturdy reinforcement web embedded within the helmet's foam increases structural support and impact dispersion


  • 23 Wind Tunnel vents
  • Fusion process allows better sculpted ventilation systems to reduce weight and keep you cooler
  • Wind Tunnel ventilation system thrusts cool, fresh air over and around the riders head-while forcing heat and stale air out
  • 23 strategically sculpted vents work in conjunction with the internal exhaust channels to move cool, fresh air over and around your head


  • In-mold technology fuses the expanded polystyrene liner with the polycarbonate shell to create a structure that's lightweight and strong

Good investment

Bought this helmet for my road bike. I use this helmet while commuting to work, on rides up to 60 miles at times, and now for my mtb. I've used it in every season and it vents extremely well. The straps are easy to adjust for a very custom fit. I need to find replacement pads because I take them out and wash them often and they are coming apart. Only complaint! I think this is as much money that I would consider spending on a helmet and I feel it is worth each dollar.

Great helmet!

I purchased this because I wanted a lighter helmet. I really liked the way it felt and the style. It was easy to adjust.

The only problem I had was around the temples. It fit too tight there. This was the sm/med on and the large was too big.

I tried another helmet (Cannondale) and that one fit fine.

It is a great helmet, but like anything, it has to fit. :-)

This helmet fits very comfortably and offers great protection. I was just in an accident with a car yesterday. I was thrown off my bike and the helmet took the impact just like as it was designed. I had no head injuries and I am going to purchase the exact same helmet as a replacement. I would highly recommend this helmet because of its excellent fit and protection.

A helmet that feels solid but still light and breathable like the ionos or prolight. I turned to this after breaking the side straps on an ionos and will probably not go back. Doesn't quite disappear while running or rollerskiing but close ...

I've owned another Giro with similar retention and rocloc. Fully impressed, hardly ever notice it on my noggin, looks good, weight barely there. Plenty of ventilation, I have a very large oval head and the giro feels good.

Stylish but uncomfortable.

I really liked the helmet but unfortunately it felt like my temples were getting pinched. I had it for a couple weeks and felt some discomfort but discounted it. Then I went on a century ride. I usually like to chew gum on longer rides and I did and ended up with a headache. I got rid of the gum and felt Bert then finished my 100 mile ride. I returned it the next day and purchased a Cannondale helmet. VERY Happy now.

My advise is go with your initial gut feeling if something doesn't fit. Overall I liked the helmet but it didn't fit my head.
