■ Record-High Heatstroke Emergency Transports in 2025: Cooling Large Areas of the Body is Effective

With recent extreme heat, the number of emergency transports due to heatstroke has been rising. The Ministry of Internal Affairs and Communications reported that in 2025, the number of people transported reached 100,510, the highest since records began. As a countermeasure, cooling the skin surface to lower subcutaneous blood temperature is known to be effective. Research suggests that cooling a large surface area of the body is more efficient than focusing only on major arteries, making products that cover a wide area highly effective in hot environments.

■ 'ZAMST COOL SHADER' Series Re-released Following Popular Demand

Launched in 2020, the 'ZAMST COOL SHADER' has become a staple for sports, outdoor spectating, and leisure. Its ease of use—simply wet, wring, and shake to activate cooling—combined with UV protection, has made it a hit. With cumulative sales surpassing 100,000 units in 2025, the series has expanded to include the 'Active Vest' for better mobility during play. In response to continued demand, the 2026 models now feature new technology that blocks approximately 74% of near-infrared rays to improve comfort during sports activities.
