【Industry's first in 2025 & cooling plate equipped Peltier cooling vest】 Bulonchi has announced the next-generation Peltier cooling vest, which boasts the industry's strongest cooling performance. It adopts the latest semiconductor physical cooling technology and is equipped with a large-area cooling blade. When worn on the back, it brings an icy coldness to the skin in just one second. The standout feature is its industry-leading cooling temperature of -28°C. The overwhelming cooling effect provides an extreme cold experience that feels painful to the touch. This 2025 model cooling vest is ideal for outdoor work and leisure activities, and we confidently recommend it to those working in scorching heat. In addition to its ability to maintain coolness throughout the day, it boasts a wide-area coverage design with twice the cooling area of conventional products.

【Instant cooling & maximum -28°C & ultra-cool sensation!】Utilizing the characteristics of Peltier elements, which are also used in refrigerators, the electronic cooling effect spreads a powerful -28°C chill from the back to the entire body in just 2 seconds after turning on the power. Aluminum blocks absorb heat and physically suppress body temperature rise, alleviating heat-related stress! Made from ultra-thin material, it doesn’t bulk up and can be worn as an inner layer under fan-equipped workwear. Since it uses Peltier-style cooling that directly absorbs heat through metal surfaces without using air, there’s no worry about clothing bulging and getting in the way during work. It’s designed to be optimal for preventing heatstroke in summer.

It can be used continuously for up to 8 hours, maintaining comfortable cooling all day long even on hot summer days. • Strong mode: -28°C cooling compared to outdoor temperature (approximately 5–6 hours of operation) • Weak mode: -18°C cooling compared to outdoor temperature (approximately 7–8 hours of operation) *Usage time is measured when using a 20,000mAh mobile battery. *Usage time is only an estimate and may vary depending on wearing conditions, usage environment, and number of charges.

【Lightweight, Compact, and Quiet Design】The compact and lightweight design minimizes physical strain, providing a comfortable wearing experience. When worn on the back, it feels almost weightless, allowing both hands to move freely, enabling you to concentrate on work or study while relieving the stress of heat. Additionally, it features a Japanese-made quiet motor with an operating noise level of just 30dB (quieter than an air-conditioned garment), allowing you to use it without disturbing those around you. Even on extremely hot days, it delivers stable cooling performance, providing comfortable coolness to prevent heatstroke while improving work efficiency. It features an adjustable shoulder strap with a Velcro closure for easy on/off. Available in sizes from S to 5L, it fits a variety of body types.
