Mobile battery not included.

Cools the surface temperature by up to 3°C, achieving a maximum of -22°C (※1) from the ambient temperature, so even in extreme heat, the surface feels as cold as ice and you can feel the coolness directly on your skin. Made from lightweight, stretchy fabric, it fits the body and is easy to move in.

One size fits all, so it can be shared with family and coworkers.

It is also quiet, so it won't be a nuisance even in quiet places such as offices.

It is versatile for various activities such as tent setup during camping, BBQ, gardening, fishing, running, light work, and events. When the ambient temperature is approximately 25°C, the temperature difference between the device surface and the ambient temperature

※When using a mobile battery with a capacity of 10,000mAh or more and an output of 2.2A or more (fully charged), please use a mobile battery with a total output of 5V/2.2A or more.

※Test environment temperature and continuous usage time are values measured when fully charged. Actual values may vary depending on usage conditions and environment. Turn on the switch and feel the cooling effect in about 10 seconds!

The surface temperature can be cooled down to a maximum of 3°C, achieving a maximum temperature difference of -22°C from the ambient temperature. Equipped with a Peltier element! A cooling vest that can withstand extreme heat | This cooling vest uses a Peltier element powered by electricity to instantly cool the body.

Regardless of outdoor temperature or humidity, the Peltier element itself becomes as cold as ice on the surface, allowing you to feel the coolness directly on your skin even in extreme heat.

Additionally, the Peltier vest does not use fans, so it does not cause clothing to bulge, featuring a sleek and quiet design.

It is also advantageous for use in dusty or powdery work environments where wearing fan-equipped clothing is difficult. Three Peltier devices | When worn, the three Peltier devices are positioned around the neck and under both arms to enhance cooling efficiency and evenly cool the entire body.  

Unlike ice packs, they do not “melt,” so the coolness lasts for a long time, providing stable cooling effects. Four-stage temperature adjustment function | The temperature adjustment function includes weak, medium, and strong settings, plus a “flicker mode” for strong settings, allowing for four-stage adjustment.  

It can be used according to the situation. Experience repeated cooling! Flicker mode | To avoid cooling numbness, where prolonged contact with the cooling surface causes the skin to become numb and less sensitive to cold, the “flicker mode” alternates between 10 minutes of operation and 2 minutes of off time.

This mode temporarily turns off the device to raise the temperature of the contact surface, allowing you to repeatedly experience the cooling effect when it cools again. Stretch fabric | Made with stretchy fabric that fits snugly to the body.  

It stays in place even during active movements like running, providing comfortable wear.  

It combines ease of movement with cooling effectiveness. Slim & lightweight with a stylish design | The Peltier vest features a slim, stylish design.  

It is lightweight and comfortable to wear. One-size-fits-all design | Unisex design makes it suitable for family members or coworkers to share. Adjustable with front and underarm belts, accommodating chest circumferences from 80 cm to 108 cm and heights from 155 cm to 185 cm.

Suitable for a wide range of body types, from slender to larger builds. Storage pockets | The front features a dedicated pocket for storing a mobile battery and a zippered pocket for securely carrying small items like keys. *The photo shows an iPhone 14, but some models may not fit. Excellent breathability | Made from mesh material, it stays comfortable even when sweating. Versatile for various scenarios | Ideal for outdoor work in intense heat, commuting, setting up tents during camping, BBQs, gardening, fishing, running, light work, events, and more. Water-resistant design | IPX
