Giro Trella matte grey dark teal bicycle helmet (GR-7100248)

Advanced Technologies

The Giro Trella W bike helmet stands out for its use of modern technologies that provide a high level of safety and comfort. The shell made with In-Mold technology combines the outer shell with the impact-absorbing inner layer, which increases the helmet's durability and lightness. This allows for effective energy dispersion upon impact, which is crucial for head protection.

Adjustment System

The Roc Loc Sport adjustment system is an innovative solution that allows precise fitting of the helmet to the shape of the head. Thanks to this, the helmet not only stays securely in place but also provides maximum comfort during riding. The adjustment is simple, allowing quick helmet fitting even while riding.

Ventilation and Comfort

Excellent ventilation is another advantage of the Giro Trella W helmet. The ventilation system was designed to ensure optimal airflow, preventing the head from overheating during intense rides. Ventilation affects not only comfort but also the overall well-being of the cyclist.

Functionality and Aesthetics

The helmet features a practical visor that protects against intense sunlight and rain, making it an ideal choice for various weather conditions. The buckle type fastening ensures ease and speed of putting on and taking off the helmet, which is important for those who value convenience and functionality.

Universal Sizing

The Universal Fit Sizing technology was developed so that the helmet fits most heads without the need to choose a specific size. Thanks to this, the Giro Trella W is extremely versatile and can be used by different people, which is a great advantage for users looking for universal solutions.

Universal Fit Sizing
A system in Giro helmets that allows them to fit different head sizes. The brand has combined a suitable shell construction with an advanced fit system to make the helmets versatile. They comfortably adapt to the shape of the cyclist's head from the first fitting. Plus - they look good.
Roc Loc Sport Fit System
The Roc Loc Sport Fit System technology is an innovative fit system for sports helmets that allows for easy adjustment. Thanks to a one-handed mechanism, the user can adjust the size of the helmet within a range of as much as 7 centimetres. Importantly, the system gives clear feedback - both in the form of clicks and perceptible changes, informing the user of the adjustment in progress.
In-Mould
In-mold is a manufacturing method in which the outer shell of the helmet is permanently bonded to a layer of inner protective foam during moulding. This makes the helmet lighter, more durable and better absorbs impacts. The process also provides an aesthetically pleasing finish and increased structural durability.
