Giro Selector TT Helmet - UnboxingGiro is one of the most recognizable producers of bike helmets in the world. This is largely because they have combined a number of proprietary and innovative techniques that allow their helmets to be used by anyone regardless of whether they are casual cyclists or professionals taking part in championship races. The helmets not only have top of the line safety features, but they are also very recognizable because of their bold graphics and sharp details. All of the benefits of Giro bike helmets come at a cost, however, because many of the higher end helmets command a premium price.One noticeable feature of Giro bike helmets is the attention that is paid to the fit of a helmet. When purchased, Giro bike helmets usually include a number of adjustable straps as well as a soft interior that makes the proper amount of contact between the head and the helmet for maximum safety. Additionally, most helmets include a series of small self-adhesive pads that can be attached to the inside of the helmet to fill gaps where more support is needed, or to allow slightly larger helmets to be worn by those with a smaller head.For safety, Giro bike helmets are made from a polycarbonate shell on the outside that is resilient and that can resist sever impacts. The shell is welded to an inner network of a special foam lining that crisscrosses the head in a way that absorbs the energy of an impact while still allowing air to flow freely over the scalp. The combination of lightweight materials produces helmets that are very durable, while also being very light when worn.In addition to casual bike helmets, Giro also produces many custom helmets. Some of these are long and sleek to allow a cyclist to take on a very aerodynamic profile while racing, and helmets that are designed with protective features in the front for dirt biking and off-road cycling. Giro bike helmets are an immediately recognizable brand that is often punctuated by general, bright graphics on the outside of the helmet, as well as custom graphics that can be done to order.
