Next-generation heatstroke measures achieved through all-in-one technology: surface water-cooled clothing.
Product Name: Wearable Water-Cooled Suit K2 Model: K2 Description: This is a new type of water-cooled suit from Cool Smile, re-evaluating the challenges of previous water-cooled suits and offering a new proposal. It was born as Cool Smile's first all-in-one water-cooled suit, providing the same cooling power without the need for a water-cooled pouch. It is simple and easy to use, making it suitable for various heatstroke prevention scenarios. Everything you need is included except for the (USB) battery. You can use your existing smartphone charging battery. We strongly recommend purchasing a freezer (available on the general market for 20,000 to 30,000 yen). It can be used as a storage unit during off-seasons. Approximately 15°C water spreads throughout the entire suit via thin surface water-cooling pipes, providing very powerful cooling. The coldness is easy to get used to, resulting in minimal discomfort even during extreme heat. We developed a unique bottle that allows for instant bottle replacement. You can perform the exchange operation while wearing the suit by yourself. This makes the actual operation of the water-cooled suit extremely comfortable.

Bottle replacement can be done while wearing it. In the previous human air conditioning series, bottle replacement was emphasized. The replacement speed has evolved while inheriting the same speed. You can quickly replace the bottle with one hand. By inserting it along the inside and side of the clothing and pushing it in, the bottle can be easily inserted. The key point is that this can be done quickly by just one person.

It can be seen that it spreads throughout; the patented technology and surface water cooling structure cools very well. Cool Smile has achieved the world's first technology to pass water through a water cooling pipe with a thickness of about 1mm. Because it can circulate cooling water thinly and extensively, it can absorb a lot of heat from the body. Furthermore, the flexible water cooling pipe that conforms to the body results in high-performance clothing suitable for various activities.

See the overwhelming cooling power of the human air conditioner K2 through thermal imaging. It absorbs body heat with its ultra-thin surface. The temperature of the blue areas is approximately 15°C, achieving stable cooling through constant circulation. You can see that the water cooling pipes spread thinly and widely throughout the entire clothing vest.

Benefits of All-in-One Water-Cooled Clothing Unlike conventional water-cooled clothing, the garment and pump unit are not separate, eliminating exposed tubes and the worry of them getting caught. Since the garment and pump unit pouch are not separated, it can be produced at a lower cost. Weight is distributed on the shoulders, allowing for better cooling throughout the entire garment, contributing to increased cooling power. With fewer parts, it has become easier to handle. It can be used with a full harness. Wearing an outer garment feels less awkward.

To the rider as well.

Can be used with mandatory full harnesses Since 2022, full harness equipment has been mandatory during scaffolding work at construction sites. As a result, there is a demand for easy-to-handle water-cooled clothing. The new human air conditioner K2 addresses this issue, and using it while wearing a harness is not a problem. Bottle replacement is possible even in this state. The human air conditioner K2 is designed to be worn as underwear, and work clothing is recommended as an outer layer.

The crescent-shaped bottle fits snugly against the body, wrapping around it. As can be seen from the side and back, the human body has an S-curve. Since the crescent-shaped tank is mounted in the space above the waist, it reduces discomfort. Additionally, the waist belt tightens the bottle towards the body, making it easier for the weight to blend in with the body, which is the secret to feeling lighter even with the same weight. The bottle also has an S-shaped design in the vertical direction, providing stability against the spine.
-
Can be washed hygienically every day The simplified K2 can be fully washed in a washing machine. It can be used hygienically every day. To wash it, remove the battery and motor pump, place the K2 in a laundry net, and wash it together with regular laundry. No dryer is needed. Most of the moisture will be removed during the spin cycle, and it can be worn immediately after being taken out of the washing machine. *Note: Hot air drying is not allowed.

Insulated structure for heat escape prevention in water-cooled clothing. The insulation layer that has been equipped in previous water-cooled clothing models EZ3 and EZ3R is now placed on the outside of the water cooling tubes. This not only allows for longer cooling times by retaining the cool air inside the clothing, but also achieves energy savings. During motorcycle touring, preventing the escape of cool air caused by the wind received from the front significantly improves the cooling retention capability.
