As an engineer, it's easy to get lost in the data of impact tests and material specifications. But after 17 years, I’ve learned that one of the most important safety metrics for a safety helmet cannot be measured in a lab: wearability. A helmet can have the highest safety ratings in the world, but if it's uncomfortable, heavy, or hot, people won't wear it correctly, or they won't wear it at all. The safest helmet is the one that is actually on someone's head when an accident occurs. This is why my design philosophy at SPIRIT is human-centric. We obsess over the details of comfort—the feel of the padding, the ease of adjustment, the effectiveness of the ventilation. We strive to make our helmets so light and balanced that the user forgets they are even wearing one. By prioritizing the human factor, we increase compliance and, in turn, dramatically improve real-world safety outcomes for every safety helmet we produce.
