Criteria Used for Evaluation

Protection

Safety is one of the most important factors to consider if you cycle. This is why helmet designs are consistently being upgraded–to ensure your safety and comfort during all of your races. You never know when an accident may occur, so it’s important to cover all your head properly. In the United States, the Consumer Product Safety Commission (CPSC) must approve the product, in Europe, the Conformité Européenne (CE) must approve the product, and in Australia, the AN/ NZS must approve the product.

The helmets on our list are designed to provide you with the protection you need during your triathlons. Even the helmets that help improve your performance and shed time off your race. However, none of them sacrifice safety or protection to improve your performance--if you are a serious triathlete you will look for a helmet that does both.

Make sure to look at reviews from other sources when searching for the right helmet for you. We did this while compiling our list but we encourage to do the same as you narrow down you choices.

Comfort

The fit is the most important aspect because it ensures your comfort and effectivity of your helmet. Make sure your helmet provides a snug and secure fit and that it isn’t too loose. If the fit isn’t right for you then you will not be covered in the case of an accident and won’t receive the safety the helmets are meant to provide you with. The straps on the helmet should also form a V and when you twist your helmet there should be very little movement. The strap will allow you to adjust your fit and ensure your comfort and safety.

When looking at comfort we also considered how it feels over time. Some helmets feel great at first but can get uncomfortable as you sweat during your rides. We also took a look at the materials the straps are made of as well as what the helmet is made of overall. Make sure to try it on for size and if you order online take advantage of any return policy offered--sometimes you just don't know (no matter how perfectly you measure everything) hoe something will fit until you try it on.

Weight

Typically, the lighter the helmet, is the more money it will cost you. While this may sound ridiculous to some of you, this is because it is extremely difficult to make a helmet that is both lightweight and able to provide you with the safety you need. Lightweight helmets will allow you to gain speed and help you shed precious seconds off your race time.

This doesn't mean you have to go for the lightest helmet. If your budget allows and you are serious about shedding seconds then go for it--but there are plenty of excellent options to choose from that are lightweight but more affordable. Some of the helmets on our list may weigh close to a pound while others way far less. In the end, when it comes to weight yes, the lighter helmets are better because they will decrease your time. However, they aren't for everyone and they may be more uncomfortable when compare to slightly heavier counterparts.

Breathability

Breathability will increase your comfort levels and is crucial for triathletes. However, more airflow requires less padding, which in turn takes away from the safety the helmet provides you with. This is why many helmets employ special channels on the inside as well as holes on the outer part of the helmet. This allows the helmet to be padded and safe–while also preventing you from sweating excessively.

These vents will allow air to flow through and cool your head--so you stay as cool and dry as possible. The last thing you want is for your head to overheat during a race. This may force you to have to stop which will mess up your time and put you behind. Helmets that don't provide the breathability you need may cause chafing and push you to have to buy a whole new helmet (yet again) because of how uncomfortable it is. Make sure to consider what you need and pick accordingly.

Fit

When it comes to fit, it is incredibly important to find something that fits you perfectly—especially when it is something you are wearing. Although the fit is incredibly important when it comes to the clothes and shoes that we wear, it is important to remember that this applies to triathlon bike helmets as well. We looked at several different factors when we considered the fit of each of the helmets on our list, but it is important that you apply all of these to your own personal needs and preferences.

Size

Size and style because they can affect many other factors. A helmet that is too small can be too tight and will decrease your blood flow. On the other hand, if the helmet is too large it won’t provide you with the safety and protection you need when you are out on your bike. If your helmet is too big there are caps you can use to make it fit better.

Padding

While not all triathlon helmets have a lot of padding, most of them have at least some padding. The best part about the padding in triathlon helmets is that it doesn’t weigh you down without sacrificing comfort and ensuring that you are comfortable and well-protected. Padding can affect the fit of the helmet, so make sure that you get the sizing right and don’t be afraid to exchange the helmet (as long as it is allowed by the retailer) if you purchase one that just doesn’t fit you properly.
