MiHIGH
MiHIGH is a portable infrared sauna blanket that uses invisible wavelengths of light to heat up to 167°F (75°C) and preheat in up to five minutes. It's made from heat-resistant artificial leather with a waterproof lining and is designed to be used while lying down. The MiHIGH emits far infrared wavelengths, which are said to penetrate deeper than electric heat or hot air.
