Our Dual-Heat Technology

Our patented heating technology combines topical and Far Infrared (FIR) heat to deliver a more complete, effective warming experience. Topical heat provides fast, surface-level warmth that helps relax muscles and ease stiffness right where you need it. FIR provides deeper, longer-lasting warmth that promotes healthy circulation and supports your body’s natural recovery process.

Benefits

  • Promote healthy circulation

  • Support relaxation and muscle comfort

  • Elevate Body Temperate

  • Ease Muscle Stiffness & Discomfort

  • Support Natural Recovery

  • Reduce Inflammation

How It Works

FIR is a non-visible, longer-wavelength energy on the electromagnetic spectrum. This energy interacts with the body and is known to reach deeper into muscles and joints, helping you feel more relaxed, mobile, and ready to move.

Backed by Science

Explore independent research supporting the benefits of Far Infrared (FIR) therapy across recovery, circulation, and pain relief.

FIR heat has been shown to help reduce chronic pain and improve circulation, especially in people with cardiovascular and musculoskeletal conditions.

FIR therapy has been widely studied for its positive effects on pain relief, improved circulation, faster recovery, and reduced inflammation throughout the body.

FIR therapy has natural anti-inflammatory benefits and has been shown to improve blood flow while reducing stiffness, soreness, and discomfort.

Consistent use of FIR therapy has been linked to lasting cardiovascular improvements, better circulation, and overall wellness gains over time.

In a controlled clinical trial, athletes wearing FIR-emitting clothing experienced faster muscle recovery after exercise, supporting better performance and reduced fatigue.
