A cycling helmet is an essential piece of equipment that can prevent severe head injuries or even death. It is important to choose a cycling helmet that fits your head properly, and it is also vital that you do not ever buy a used helmet; only consider a new cycling helmet for purchase, as used helmets may have hidden cracks that can compromise the integrity of the helmet. Used helmets may also become brittle with age, meaning they will not adequately protect your head. Choose a helmet that fits your budget, too, as helmets range from very inexpensive to prohibitively expensive.
All cycling helmet offerings from recognized companies are built to the same safety standards, and in order to be offered for purchase, every helmet must be inspected for quality and correct construction. In other words, no one brand of helmet is safer than another. All helmets must meet safety regulations, ensuring any helmet is safe enough for regular use. Finding the best helmet is therefore a matter of finding a helmet that looks good and fits well. The styles and shapes of helmets will vary significantly, and many helmets feature elaborate shapes to cut down on weight and to increase venting capabilities, keeping your head cool and dry throughout your ride. Look for a helmet that is well-vented and seems sturdy.
Most modern cycling helmet models feature adjustable fit systems that will allow you to cinch the helmet down snugly on your head. The fit system should be easy to use and should hold the tightness regardless of head movement throughout the ride. If the fit system features a dial, be sure the dial can be moved easily with one hand so you will be able to adjust the helmet's fit on the fly without having to stop your bike to perform this task. Be sure the neck strap can be adjusted as well, and check whether the strap will adjust snugly but not uncomfortably underneath your chin.
If you are a mountain biker, consider a helmet with a visor. Cycling helmet visors will help block sun, and they will also help stop branches or other debris from striking your face while riding. Many helmets feature removable visors so you can use the helmet for either mountain biking or road cycling. The visor will affect the aesthetics of the helmet, so be sure to consider whether this design appeals to you or not.
