Petzl Sirocco Helmet

In short, the Sirocco is a ground-breaking helmet with new technology that I’ll wager (and hope) will trickle down to less pricey models. I’ve been a tough sell on helmets, finding just about every other lid lacking, usually because of weight. With the Sirocco, I’m out of excuses.
I gave the Sirocco four of five stars, deducting one star only because the helmet is bulky.
