	VOLZZA

Functions & Technology

■Semi Floating Structure
Achieved stable fitting by uniformed tightning.

Semi-floating structure

■Better fitting for round type head shape

The shape of a human head varies by race, gender, and generation, and therefore varies greatly depending on the region where the helmet is sold and the target user. Many overseas brand helmets often adopt a vertically long oval shape, and in the area of Asian races, which often have a circular (round) head shape with a protruding temporal region, if the size does not match the actual head size, you may experience headaches or discomfort if you wear it forcibly, or you may be forced to wear a helmet that is one size larger to match the size.

Based on the head shape data that Kabuto has collected over the years, VOLZZA has been designed with the optimum shape so that many users can wear it comfortably

■Air route designed more cooling efficiency than the same class models.

VOLZZA has an excellent air route design inherited from the Kabuto flagship model "IZANAGI", which boasts the highest air cooling efficiency, and an efficient air hole arrangement, so even in "air cooling performance comparison verification ★" with helmets of the same class. It demonstrates top-class air cooling efficiency.

★ "Air-cooling performance comparison verification" with helmets of the same class by in-house wind tunnel experiments

[Verification conditions]

Measure the decrease time of the head surface temperature with our own wind tunnel equipment.

* Reference value for our own wind tunnel facility

[inspection result]

In-house wind tunnel experiments proved that the air cooling effect is up to "9%" higher than that of helmets of the same class.

Comparison with helmets of equivalent class by in-house wind tunnel experiment	Up to "9%" higher air cooling effeciency than helmets of the equivalent class

■KBF-2 Adjuster equipped with "BOA®Fit System" *1

Allows for uniform tightening and fine adjustments to the fit of the helmet. Large dial has a easy-to-catch on fingers design that makes quick, one-handed adjustments possible.

■ COOLMAX® to maximize the air cooling effect

In addition to the original air-cooling performance of the helmet, the fabric quickly evaporates sweat and keeps it smooth and comfortable at all times with "COOLMAX® * 4", which lowers the body surface temperature and demonstrates an excellent moisture adjustment function.
