Summer, when heat drains your energy. You no longer have to endure it.
According to the Japan Meteorological Agency, the summer of 2025 recorded the hottest summer ever observed, and data from the Fire and Disaster Management Agency showed that the number of emergency transports due to heatstroke reached a record high. In outdoor work environments, "heat countermeasures through equipment" have become more important than ever.
Amidst this, NiZmir has reflected the voices from the field and solved all the challenges that conventional air-conditioned workwear fans faced: "insufficient airflow," "poor battery life," and "inability to achieve expected cooling effects." The latest 2026 model is now available, equipped with 52V ultra-strong airflow, a Peltier cooling plate (up to -24°C*), and a 40500mAh large-capacity battery.
Furthermore, to commemorate this new release on Rakuten, a limited-time 40% OFF coupon is being distributed. You can purchase it for 8,388 yen, down from the usual 13,980 yen. The campaign period is from 7:00 PM on Thursday, April 30th, to 11:59 PM on Tuesday, May 5th. As last year's records show, the summer of 2026 is also expected to be extremely hot. Now is the best chance to prepare before the heat intensifies.
■ Why is it cool? — Two Cooling Mechanisms
The coolness of this product comes from a mechanism that combines two elements: "evaporative cooling by forced convection" and "direct cooling by the Peltier element."
Forced Convection: Sweat's Evaporative Heat Dissipates Body Heat
Forced Convection
The most efficient way to lower human body temperature is through the evaporation of sweat. The phenomenon where sweat absorbs heat from its surroundings as it turns into gas is called "evaporative heat."
The product's 52V high-output fan sends 249 liters of powerful airflow per second into the clothing, instantly expelling hot and humid air. This efficiently generates evaporative heat, significantly lowering the perceived temperature.
Peltier Cooling: Actively Creates "Coldness"
Fans alone have limited effectiveness in extreme heat above 35°C. Therefore, this product is equipped with a Peltier cooling plate. A Peltier element is a semiconductor device where one side absorbs heat and the other side emits heat when a direct current is applied.
The plate surface (skin side) cools down to a maximum of -24°C, and this coldness is directly transmitted to the back and chest. Simultaneously, the fan circulates this cold air throughout the inside of the clothing.
Peltier Cooling
Synergistic Effect: Experience "Refrigerator-like" Coolness
While the Peltier plate directly cools the skin, the fan expels hot air and circulates cold air. Furthermore, evaporative cooling from sweat is also promoted simultaneously, allowing you to experience "refrigerator-like" coolness even on hot days with high outside temperatures.
■ Evolution of the 2026 Model
・40500mAh Large-Capacity Battery
Up to 20 hours of continuous use. Fully charged in about 5 hours. Feel secure for all-day outdoor work or long camping and fishing trips.
・6-Stage Airflow + 5-Stage Cooling Adjustment
Airflow and cooling can be finely adjusted independently. You can freely set it according to the scene, from strong wind mode on scorching hot days to mild settings at night.
・Easy Installation - 3 Steps
Simply remove the fan ring, pass the fan through the vest, attach the ring, and connect the cable. Even beginners can complete installation in 5 minutes.
・PSE Certified + 1-Year Warranty
Equipped with multiple protection functions such as overheat protection, overcurrent protection, and short-circuit protection. PSE certified with a 1-year warranty. Safety is also perfect.
■ Applicable Scenes
It is widely active not only in outdoor work such as construction sites, construction, agriculture, and transportation, but also in camping, fishing, touring, sports spectating, and warehouse work.
It is effective even in summer field work and poorly ventilated indoor work. One device for both work and leisure.
