Product Description:
Take a wellness cue from the likes of celebrities world wide and take your DOSE on the go. Perfect for traveling or at-home use, the HigherDOSE Infrared Sauna Blankets increase the body’s thermal energy and promote a temporary increase in blood flow–so you sweat like you’re working out, without working out. As you relax into the soothing, yet stimulating heat, infrared also provides an uplifting sensation. The result? A healthy, rejuvenating experience that leaves you feeling euphoric.

• Non-toxic PU Leather Body and Industrial Zipper
  Passing all non-VOC standards, our elevated polyurethane leather body material is better for you and the environment while remaining as waterproof as earlier models. We swapped velcro for an industrial zipper, making the V4 blanket a roomier experience, an easier exit, and more comforting for those with a weakened immune system.
• Far Infrared Heat
  Infrared’s deeply penetrating heat promotes full-body detox, improved circulation, reduced inflammation, and inside-out healing.
• Charcoal, Clay & Magnetic Layers
  Charcoal binds to pollutants, helping to flush out impurities and deepen your detox. Clay layer emits negative ions and balances the heat. A grounding medical-grade magnetic strip improves blood flow and circulation.
• Crystal Therapy
  Healing amethyst & tourmaline layer deepens the benefits of infrared and naturally generates negative ions, which fight free radicals.
• Grounded In Low ELF
  Our innovative blanket design is low in EMF (Electromagnetic Field) and in ELF (Extremely Low Frequency) currents – setting the standard for healthy and safe at-home infrared experiences everywhere.
