This isn’t just a heated blanket; it’s an infrared sauna to wrap yourself up in. Just turn on, pre-heat, tuck yourself in, and let infrared heat do its magic. And HigherDOSE made upgrades from the previous version: This time, the sauna blanket gets even hotter. Preheat the blanket for 10 minutes, hop in, and emerge in half an hour—glistening and feeling (really) good. Waterproof polyurethane and fireproof cotton 71" x 71" unfolded Used once. Price includes upgraded postage required for shipping.
