The new Ultra Freezer Core goes beyond the conventional concept of fan-equipped clothing and was born as the “ultimate cooling wear” that can be used in a wide range of situations, from work sites, outdoors, sports, and daily life. This product uses environmentally adaptive multifunctional technology and is equipped with an innovative mechanism that allows comfortable temperature adjustment even in harsh environments. Additionally, in collaboration with Air Conditioning Co., Ltd. (Tokyo), we have achieved even greater comfort by utilizing the company’s high-performance fans and batteries, and in combination with the environmentally adaptive multifunctional technology of “Caballos” promoted by hap Co., Ltd. In particular, the inside of the hooded zip-up vest provides the comfort of wearing an air conditioner, making it ideal for working environments under the scorching sun or for outdoor activities. [Issues with conventional fan-equipped clothing] In recent years, clothing with fans has become popular as a standard item to protect against extreme heat, but the following issues have been pointed out. ・If the outside temperature is too high, you will only be blowing in “hot air”, which will actually make you feel hot – Wind is not distributed evenly, resulting in uneven cooling effect ・If the wind pressure of the fan is too strong, unpleasant stuffiness will occur inside your clothes ・The design is similar to work clothes, making it difficult to use on a daily basis ・Difficult to use for long periods due to limited battery life To address these issues, Ultra Freezer Core provides overwhelming comfort through new cooling technology. [3 major innovations of “Caballos Ultra Freezer Core”] 1. “Wearable cooler” that generates cold air Conventional fan-equipped clothing has a mechanism that draws in outside air and sends it out, so in environments where the temperature exceeds 35 degrees Celsius, only lukewarm air is generated. The Ultra Freezer Core is equipped with a patent-pending instant cooling system that continuously sends cold air into the clothes by drawing in air with a fan and passing it through a dedicated “Ultra Freezer Ice Pack” (high-performance insulating ice pack unit). Furthermore, by using a vapor-deposited aluminum material with high thermal conductivity, it is difficult for the cold sensation to escape from between the fibers, making it possible to maintain the cool sensation inside the garment. This allows you to work under the scorching sun while being exposed to cold wind, making it comfortable to wear for long periods of time. Converts conventional product’s “hot air” to “cold air” Stable cooling effect even in environments with temperatures above 35℃ Reduces perceived temperature by up to -10℃ even on extremely hot days

Long cooling duration & environmentally friendly battery The Ultra Freezer Core has a high-performance battery and an energy-saving cooling system that allows it to last for a long time. The dedicated battery lasts up to 24 hours, and at maximum output it lasts about 8 hours. By utilizing the air volume adjustment function, it provides optimal cooling according to the situation. In addition, the Ultra Freezer Ice Pack has a high-performance design that keeps it cold for about 3 hours even in summer. Air volume adjustable (4-step mode) Continuous operation for up to 24 hours Energy-saving design minimizes battery consumption In addition, the battery and fan are removable and can be washed once removed. You can always keep it clean, so you can use it comfortably for a long time.

It has a design that allows it to be worn not only at work sites, but also in a variety of situations, such as camping, fishing, festivals, golf, and everyday shopping. In addition, by using a vapor-deposited aluminum material with high thermal conductivity, it is difficult for the cold sensation to escape through the fibers, making it possible to maintain the cool sensation inside the garment. Furthermore, by ingenuity in the design of the product, it is designed to maintain a comfortable cooling sensation for about 3 hours.

[Evaluation experiment through industry-academia joint research] Caballos Ultra Freezer Core is a joint research project with Shinshu University’s Faculty of Textile Science and aiESG, a start-up company from Kyushu University, and we plan to release data using AI such as “stress check”,
“quantification of heatstroke risk” and “quantification of productivity improvement” when wearing “Caballos Ultra Freezer Core” in work environments during extremely hot weather. Furthermore, we plan to conduct ESG evaluations of manufacturing processes, ESG evaluations during wear, ESG evaluations during secondary use, and ESG evaluations during recycling. [Circular fashion (rental, etc.) service] As part of our circular fashion service, we are collaborating with local governments and others, including Fashion Cross Furushima Co., Ltd. (Saitama Prefecture), and are planning to start test operation of circular fashion services (rental, repair, upcycling, optimal recycling, etc.) in May 2025. We aim to provide opportunities for as many users as possible to experience our products and services, such as products for extreme heat, cold, pollen, and disaster prevention, while reducing environmental impact. As the first step, we are planning to start a rental service for Caballos Ultra Freezer Core. ＊Release information “Caballos Ultra Freezer Core” will be on pre-sale from March 15, 2025 on the crowdfunding “Makuake”. It can be purchased at a special price only for supporters. After that, we plan to sell it on e-commerce sites.
