The Giro Prolight is a very expensive bike helmet, but reviewers say it is an excellent choice for serious cyclists. Weighing just over 6 ounces, the Prolight is one of the lightest helmets you can buy. It also boasts some impressive users -- both Alberto Contador and Lance Armstrong wore the Giro Prolight in the 2009 Tour de France. Reviewers say the Prolight helmet is incredibly comfortable, and there are three sizes available to ensure a snug fit. However, reviewers are split on how easy the helmet is to adjust. One tester finds it a little cumbersome, while another calls it "extremely easy." Twenty-five vents also ensure excellent ventilation, according to reviews. However, the price tag is hard for some to swallow. If you are shopping on a budget, the Giro Stylus (*Est. $85) also gets high marks for serious cyclists. It's not nearly as light or ventilated as the Giro Prolight, but it gets good reviews for its comfortable fit.

The Giro Prolight attracts a number of professional reviews, with the best analysis coming from U.K. cycling publications like Cycling Plus magazine and BikeRadar.com. Both sources test and rate the helmet and provide nicely balanced analysis. American publications like Outside and Bicycling magazines also have solid test-based reviews.
