Throw down.

Don’t forget the Giro Women’s Flak Bike Helmet when you’re headed to the dirt jumps. Its burly skate-influenced design takes hit after hit as you work out your tail whip, and the flow-through venting helps keep you cool as you hike up for another lap. Giro added an extra helping of open-cell foam to take some of the impact out of wrecks.

a good fit

It's hard for me to find any head gear. This one had the right shape. And it is light.If you've a big cranium, this is for you. And it looks cool.

Still too big for my little noggen

The helmet looks great, BUT it just was too big for my noggen. I purchased both the small and medium. The medium was way too big and the small was still pretty loose, so I had to return both helmets. It looked and felt super durable and light, but it was a "no go" for me.
