Warmilu is a non-electric warming technology company, specializing in manufacturing the InstaWarmer. The InstaWarmer is a safe, reusable and durable heat pack that generates safely regulated warmth in seconds. With the simple click of the activator disk, the pack begins to warm up, and stays warm for 4-6 hours when used by itself and 5-8 hours when used in conjunction with one of our insulator products. Our technology is US utility patented, and has been validated as a means of safe temperature regulation in our 2013 clinical trial. The Adult InstaWarmer is cleared by the FDA.
