Professional-grade heat countermeasures that blend into your everyday life! POINTS of "FREEZETECH Air"

- Achieves approximately 40% miniaturization of electric fans compared to conventional models (10cm -> 6cm) and approximately 10dB noise reduction! (Our research)

- Now wearable in scenes where appearance and quietness are important, such as offices and customer service.

- Supports development of uniforms for corporations, promoting adoption across various industries.

With the increasing number of extremely hot days in recent years, professional-grade items that have traditionally been focused on heat countermeasures in worksites are now also in demand for everyday use.

"FREEZETECH Air" achieves approximately 40% miniaturization and approximately 10dB noise reduction compared to the approximately 10cm diameter fans commonly used in standard fan-equipped apparel (our research). This simultaneously improves the issues of "noise, weight, and design" that have been challenges with conventional fan-equipped apparel, achieving a high level of quietness and lightness.

The miniaturized design allows for a structure that does not detract from the garment's design, enhancing comfort not only in work environments but also making it easy to wear in scenes where quietness and appearance are important, such as offices, customer service, and sporting events. This expands the application range of fan-equipped apparel, which was previously limited to worksite use, and offers a diverse lineup that is easy to incorporate into daily life, including shirts, ponchos, and vests.

Furthermore, the design of "FREEZETECH Air" was handled by Hideo Yoshii, representative of Hidesign Inc., a uniform designer highly acclaimed both domestically and internationally. Based on the design philosophy of "balancing functionality and aesthetic sense," it eliminates the "equipment-like" feel seen in conventional fan-equipped apparel and achieves a product design that naturally blends into daily life.

In the future, in addition to in-store deployment at home centers and sports retailers, we will also promote custom development for uniforms and business use tailored to the challenges and applications of individual companies, aiming for adoption across a wide range of industries.

Synergistic Effect of "Cooling Boost" and Future Prospects

Synergistic Effect with "Hyogeki" Cooling Print

By combining this fan-equipped apparel with existing FREEZETECH products ("Hyogeki" and "Hyogeki Alpha" series), the cooling effect can be further enhanced. (Due to evaporative cooling)

FREEZETECH's unique "Hyogeki" cooling print uses erythritol and xylitol contained in the back of the fabric to absorb sweat and moisture, lowering the fabric temperature through its heat absorption properties and providing a cooling sensation.

Therefore, by receiving airflow from the mini fan of "FREEZETECH Air," the cooling sensation is further intensified, allowing you to experience a higher cooling effect. (Due to evaporative cooling)

Social Contribution and Overseas Expansion

As part of the "Heat Rescue Project," FREEZETECH has contributed to heat countermeasures for a wide range of people, including workers in extreme heat, athletes, children, and the elderly.

We will continue to advance research and product development, and through strengthening our product lineup with an eye on overseas expansion, we will contribute to reducing heat risk for society as a whole.

Please look forward to the future of "FREEZETECH Air," the next generation of heat countermeasure apparel with mini fans.

What is FREEZETECH "Hyogeki Alpha"?

By integrating advanced technology, the material itself automatically controls the rise in indoor temperature. (※1, 2) It brings the indoor temperature, which heats up in extreme heat or due to body temperature rise, closer to a comfortable range, thereby enhancing the cooling effect of the "Hyogeki" cooling print. In addition to the cooling effect, it maintains comfort (※3) inside the garment.

This is suitable for those who work outdoors for long hours in extreme heat or engage in sports.
