Full face motorcycle helmets offer the most protection of all the motorcycle helmet styles. The motorcycle helmet is the most important piece of gear that you own if you are a motorcycle rider. Most states require that you wear a helmet while riding a motorcycle, but some do not.
In those states where motorcycle helmets are not required there are often injuries when accidents occur involving a motorcycle. Quite often the motorcycle helmets 
could have been avoided if the rider had been wearing a helmet.
There are many different types of helmets in terms of style, flip up, full face, off-road, open face, and shorty helmets. You should check and ensure that whatever helmet you buy meets DOT standards and that it has a Snell rating. A Snell rating means the helmet offers the highest level of production available.
Choosing a helmet is a personal choice; however a full face helmet is the best choice for a couple of reasons. A full face motorcycle helmet gives the protection of a chin bar and a tinted face shield which can also customize the look of the helmet.
The ventilation system is what makes or breaks a motorcycle helmet. Helmets that are high quality have close fitting shields and snug padding around the bottom of the helmet to cut back on the noise of the wind. The trade off with that is that it promotes fogging. Manufacturers try to avoid the fogging by installing breath deflectors at the top of the chin bar.
The best ventilation systems have air ducts in the styrofoam safety line to suck hot air away from the scalp of the rider. Manufacturers try to avoid the fogging by breath deflectors at the top of the chin bar. Try to get a field system that has a handy design that is tool free. You will find that many mid to high range helmets have this feature.
