[Product Page] https://lp.musclesuit.co.jp/coolvest2aquavest ■ Heatstroke prevention measures mandatory from June 2025; severe heat continues year by year, requiring urgent corporate action Starting in June 2025, employers are legally required to implement heatstroke countermeasures for work in hot environments. When work occurs for a certain period of time in environments where the WBGT (Wet Bulb Globe Temperature) is 28°C or higher, or the temperature is 31°C or higher, companies are required to take specific safety measures, such as monitoring workers' conditions and implementing countermeasures. On the other hand, summers in Japan are becoming more severe every year, and in fields such as manufacturing, logistics, construction, and agriculture, working in high-temperature environments remains unavoidable. Especially in workplaces where air conditioning management is difficult, many voices say, 'We want to take measures without compromising workability,' 'We don't want to increase physical burden with equipment,' and 'Power management is difficult,' leading to many cases where choosing countermeasures is a struggle. Under these circumstances, there is a growing need for practical countermeasures that can be operated comfortably on-site, simultaneously reducing work burden and mitigating heatstroke risks. ■ Lower price, same effectiveness. 'Muscle Suit COOL VEST 2' This is the latest 2026 model of the 'Muscle Suit COOL VEST' equipped with Peltier devices and fans, which was released in May 2025. In this model, the placement of the Peltier devices was reviewed and changed to positions that are less likely to hinder work. Additionally, by optimizing the specifications to the necessary and sufficient performance required on-site, the price was reduced by 26%. The dual structure, combining direct cooling from Peltier devices placed at the neck and airflow from fans, covers the issues faced by conventional cooling goods. It realizes more effective and comfortable heat countermeasures. Furthermore, the color scheme has been changed to blend in easily with on-site workwear and make dirt less noticeable. It is suitable for use in workplaces where air conditioning management is difficult, such as manufacturing, logistics, agriculture, and construction. Like the previous model, it can be used in combination with full harnesses for high-elevation work and the Muscle Suit Soft series. Price: 22,000 yen (excluding tax) Sizes: S, M, L, XL, 5L Muscle Suit COOL VEST 2 Compatible with driving vehicles and wearing equipment Fans are placed on the flanks.
