Giro Helmets Vs Bell Helmets – Which One is Better?

Getting a good bike helmet is every rider’s concern. With the many brands in the market, the task becomes nerve-wracking. But what about Giro helmets vs Bell helmets? Which of these helmets suits you or is better?

Giro helmets are more rounded to suit riders with round heads and are slightly more stylish than Bell helmets but less roomy. Meanwhile, Bell helmets are elongated to fit oval/oblong heads and are slightly roomier but less stylish than Giro helmets.

However, since both bike helmet companies share the same owner (Vista Outdoor), you can expect them to be good quality, safe, breathable, and comfortable.  

That is because they go through the same quality standards, offer the same protection, pass through the same testing standards, and their prices are almost similar. 

This guide will look at the similarities and differences between Giro and Bell bike helmets, recommend the best, and answer some questions about the topic.

Let’s get started! But before then, let’s better understand the two bike helmet manufacturing companies.

Similarities Between Giro Helmets and Bell Helmets

Just a hint, Giro and Bell helmets have so much in common than there are things that set them apart. Below are the similarities between Giro and Bell bike helmets:


As mentioned earlier, both helmet manufacturing companies (Giro and Bell) share the same owner, Vista Outdoor.

Vista Outdoor, a leading designer and sports gear manufacturer, is located in Anoka, Minnesota. 

They also have a vast chain of distribution centers in Asia, Canada, Europe, Mexico, and Puerto Rico. 

Quality Standards

Both Giro and Bell helmets define the word quality best. The two manufacturers use good-quality materials on their shells and lining. 

Their shells’ construction comprises impact-resistant material, which is why most riders prefer them. And their quality doesn’t stop there. Like mountain bike helmets, the straps and visors come from reliable and equally durable materials. 

And to add ice to the cake, these helmets come well-ventilated to give you the utmost comfort and are also lightweight. 

Testing Standards

Though Giro and Bell helmets have different testing laboratories, the testing standard is the same. That is because the two companies act per Consumer Product Safety Commission (CPSC) standards. 


If you are looking for a helmet, your topmost concern is protection and safety. Well, the two helmets give you that – protection. 

They are crafted with a Multi-Directional Impact Protection System (MIPS) that cushions your head during crashes, thus minimizing the risk of severe head injuries.  Their outer shells, on the other hand, are made from polycarbonate that reduces the impact potentially. 


Giro and Bell helmet companies employ safety and quality standards and technologies in helmet production; thus, their helmets do not differ much in price. 

Though Giro and Bell helmets are slightly more expensive compared to other brands, they give you much more price aside. They are good quality, reliable, durable, breathable, and comfortable.

Differences Between Giro and Bell Helmets

Below are the three significant differences between a Giro and Bell helmet:

1. Shape and Head Preference

The primary and critical difference between the two bike helmets is their shape.  Giro helmets are more rounded and a better choice for cycling enthusiasts with an even or round head shape.

On the other hand, Bell helmets come with an oblong (elongated) shape and are for those with an oval or oblong head. 

But should my head shape matter?

Well, not much for casual riders. However, choosing your helmet according to your head shape is a good idea if you are a biking enthusiast who rides for long hours. Also, make sure that it fits snugly for comfort. 

2. Giro Vs Bell Helmets Size

The fit aside, the other significant difference between a Giro and a Bell helmet is their size. Though both manufacturing companies make helmets in small (s), medium (m), large (l), and extra-large (xl) sizes, there is a slight difference between them—the dimensions won’t match.

While Bell’s small helmets are a bit roomier, it cannot be said of Giro, and when Giro’s large and extra-large helmets are a little bigger and accommodating to individuals with larger heads, it’s not the case with Bell. 

Below is a sizing guide for buying your ideal Giro or bell bike helmet.
