Top features to consider


Competing in a triathlon is one of those experiences that push your mind and body to its limits for extended periods, given that you have to excel at cycling, running, and swimming to finish the race.

When it comes to choosing the right gear, there are some particular characteristics that the most effective models share and that you should be aware of, especially if you are rather new to triathlons. Therefore, in the following lines, we’ll go into some of the main ones.





A helmet’s weight is one of the most important factors since this is one of those items in your gear that actually add weight to your body. Although most models are generally as lightweight as possible, the fact that you are carrying it on your head can have an impact on ventilation, comfort, and last but not least, safety.

From a safety point of view, helmets that are a bit heavier tend to be safer, since they normally include more padding and protective foam. However, in terms of ventilation, a heavier model tends to sit more heavily atop the user’s head, especially if it doesn’t feature specially designed suspension elements to create airflow channels.





Another of the primary factors that need to be taken into account when choosing a triathlon helmet, aerodynamics work to ensure that the item’s design ultimately allows you to use less energy while riding faster. Of course, this result is achieved by reducing the drag of air resistance and wind, which in turn means you are spending less energy yourself.

Some of the design elements that help in this matter include a large front of the helmet that helps blunt the drag or sweeping tails that have also become quite popular for drag reduction.





While you might think that being properly ventilated during a race is a matter of comfort, it’s important to be aware that it’s also a matter of safety. Given that triathlon competitions tend to get intense, and here we are mostly referring to the biking part since we’re talking about helmets, there’s a risk of overheating to the point where it might get dangerous.

Some cheap triathlon helmets can offer plenty of ventilation but their design might slow you down, while others can work the other way around. What you should know is that keeping your body temperature lower actually allows you to race more efficiently and probably use less energy. What you should strive for here is finding the right balance between ventilation and efficiency.

Giro Aerohead MIPS 


When looking for a good aero helmet triathlon fans might find that the features of this Giro model make it the answer to their quest.
