Achieving up to -23°C cooling: Peltier-equipped air-conditioned wear now on sale

Arclands Corporation (President: Yoshifumi Sato, Sanjo City, Niigata Prefecture), which operates the 'Musashi' and 'Vivahome' home centers, has further evolved its 2025 'Ice Triangle' air-conditioned clothing series. For the 2026 model, the company has released a new 'Peltier type' equipped with a Peltier device that cools instantly at the flip of a switch.

With record-breaking heat becoming the norm in recent years, the government has strengthened heatstroke prevention measures in the workplace, and demand for air-conditioned clothing is rising rapidly.

Combined with this growing demand, early expansion of sales floors, and the enrichment of high-functional lineups, the company's sales of air-conditioned clothing this season are trending at more than double the previous year.

Rising demand for heat protection in outdoor environments due to national high-temperature forecasts

According to the latest 3-month forecast released by the Japan Meteorological Agency, temperatures this summer are likely to be higher than average nationwide, and severe heat is expected to continue. Against the backdrop of these weather trends, interest in heatstroke prevention and body temperature regulation is increasing in a wide range of situations, including outdoor work, commuting, and leisure.

Cooler than ever with Peltier devices! The evolved 2026 model

As extreme heat is expected again this year, the 'Peltier type' has been added to the popular 'air-conditioned clothing' series to keep users cool and comfortable. It achieves cooling performance of up to 23°C below ambient temperature. Furthermore, while maintaining features popular in last year's models, such as the 'Ice Triangle' which cools the neck and both underarms simultaneously with ice packs, and the ultra-large 75L airflow fan, the new model has evolved into an even more comfortable cooling experience.

Features of Peltier device products

- Peltier Device: Achieves cooling of up to 23°C below ambient temperature through the cooling effect of Peltier elements. - Side Fan Specification: Fans are located on the sides, making it less intrusive when sitting, such as while driving. - Side Button Specification: Peltier devices and fans can be operated via left and right side buttons, allowing intuitive settings changes while worn. - Peltier Adjustment Belt: Allows for positional adjustment of the Peltier device, increasing contact and maximizing cooling effects.

Safe even in extreme heat: PD 30W compliant semi-solid battery resistant to ignition and thermal runaway

The mobile battery included with the Peltier set adopts a semi-solid electrolyte, achieving high safety. In addition to supporting maximum 30W rapid charging and simultaneous charging of two devices, it features a long lifespan of approximately 2,000 cycles and a low self-discharge design, ensuring peace of mind even in harsh, hot environments.
