The BOA® Fit System is an advanced mechanism that allows for precise adjustment of the helmet's fit to the shape and size of the skier's head. This ensures that the helmet fits snugly, which is crucial for comfort and safety. This system allows for easy and quick adjustments, even while wearing gloves, which is extremely useful on the slopes.

The ear pads made of EVA material provide a soft and comfortable layer that offers additional protection for the ears as well as thermal insulation. These ear pads can be easily removed, which facilitates cleaning and allows for individual adjustment to the user's needs, enhancing listening comfort and awareness of the surroundings while riding.

The internal ventilation channels in the Dainese Nucleo helmet effectively manage airflow, directing excess heat and moisture away. This system keeps the head dry and cool, which is crucial for comfort and concentration while riding.

The hybrid REVERSE construction in the Dainese Nucleo helmet combines a lightweight outer shell with multi-layer ABS protection. This solution merges the advantages of the lightness and flexibility of the outer shell with the durability and protection offered by ABS, ensuring optimal head protection.
