Joe F.wrote a review of Petzl Sirocco Helmet on July 11, 2019
While the helmet looks like it's made out of the styrofoam your refrigerator was packed with, it's the lightest of my quiver and checks all the boxes for impact and intended use (backcountry skiing). I purchased this to replace my Smith Vantage (weighs over a pound) as my backcountry ski helmet so I'd have something I won't need to take off after a descent for the skin up. Plenty of ventilation to keep you cool, and comfortable. If you want to sacrifice a few ounces for the traditional helmet look, go with the cheaper Meteor version, it has a coating around the foam so it looks more like a traditional helmet. If your an oz counter, and want the mountain cred, then this one fits the bill. While slim on features, it has what counts, comfortable fit, protection ratings, light weight and a goggle strap (much appreciate that last one).
