Lady Heat

last updated：Nov 02, 2026

TOEI KAISHA, LTD.

Awarded the Special Jury Prize at the Disaster Preparedness Goods Awards! Simply open and unfold to generate heat. A preparation for the risk of hypothermia among employees during winter disasters when heating cannot be used due to power outages.

- No battery required; the heating element reacts with oxygen in the air to generate heat. - It is a self-heating type that physically heats (38-40°C) rather than just retaining heat. - Heats up in about 10-20 minutes and maintains heat for a maximum of 8-10 hours. - Available in three sizes, from one that covers the body to one that covers the upper body. - Multiple heating elements are arranged on a single sheet. - Sealed in a protective bag that does not allow air or water to pass through. - The flat packaging allows for easy storage and portability without taking up much space. - Not reusable, non-sterile. We accommodate bulk purchases for companies such as fire and emergency equipment-related companies, transportation companies, construction companies, etc., for stockpiling in company vehicles, logistics bases, and outdoor work sites. 【Note】 - This product may not generate heat if opened in an environment below 0°C. If using below 0°C, please open it in an environment above 0°C and confirm that it generates heat before use. - This product is manufactured to meet heating conditions even in low-temperature environments, so the achieved temperature and time may vary depending on the usage environment (variation range: up to about 50°C).
