The RejuvaWrap X™ delivers far infrared heat at 5–14 µm wavelengths via low-EMF carbon fiber heating, penetrating up to 1.5 inches deep to ease muscle tension, boost circulation, and support detox. As the upgraded model, it adds dual zippered arm holes so you can stay hydrated, read, or use your phone without breaking the thermal seal. Nine heat levels from 95–176°F and a 5–60 minute session timer let you dial in every session—and it folds down into a carrying bag when you're done.
