If you want a reasonably lightweight helmet without spending hundreds of dollars, reviews point to the Giro Stylus. This 10-ounce helmet comes in three sizes, making it more likely that you'll find a comfortable fit, and fits heads ranging from 20 to 24.75 inches. Reviewers say the Giro Stylus bike helmet is a great value, especially for those who can't justify spending money on top-end helmets. The fit-adjustment system uses a dial to tighten or loosen the fit, which can be adjusted with one hand. Reviewers also like the stylish design. However, some users note that the Stylus runs smaller than other Giro helmets. Even though the Giro Stylus has 26 vents -- a large number compared to other sub-$100 helmets -- one reviewer thinks that their small size limits ventilation. If weight is more important to you than anything else (and you're willing to pay for it), the Specialized S-Works Prevail (*Est. $230) is the best performance helmet, according to reviews. It's not cheap, but it has excellent ventilation and weighs just 8 ounces.
The best review of the Giro Stylus helmet comes from Cycling Plus, a cycling magazine from the U.K. Editors test 24 bike helmets, rating each one on a 10-point scale and summing up their findings with lengthy analysis. Road.cc, a British cycling site, also has a detailed review, although the Stylus is not compared to any other helmets. The helmet also attracts a good number of user reviews at Buzzillions.com.

Road.cc gives the Giro Stylus a 4-star rating (out of 5). While Jon Burrage finds the helmet a great value, he has a little trouble getting a perfectly snug fit with the fit-adjustment system. Overall, he recommends the helmet for bike commuters or casual cyclists.
