How Does It Work?

ThermaFlex uses targeted heat therapy and rhythmic vibration to relax muscles, improve circulation, and ease joint discomfort right at the source. As you fasten the brace, it gently warms the area—helping increase blood flow and loosen stiffness—while soft vibration massages deep into the muscles around the joint.

With simple one-touch control, you can switch between heat levels and massage intensities to match your comfort needs—whether you’re preparing for activity or winding down after a long day.

Compact, adjustable, and rechargeable, ThermaFlex can be used anywhere: at home, at work, or even before a workout. No cords, no clinics—just personalized, on-demand relief designed to keep your body moving freely.

ThermaFlex isn’t just a brace—it’s a daily ritual of comfort, mobility, and active recovery, helping your joints feel supported, warmed, and ready for whatever comes next.

Struggling with Joint Pain or Stiffness?

Whether it’s arthritis, old injuries, or sore knees after activity — the discomfort can make even simple movements feel exhausting.

That’s why we created Rexly™ ThermaFlex — a 3-in-1 heated vibration brace designed to soothe pain, loosen stiffness, and restore comfort where you need it most.

ThermaFlex delivers deep heat therapy, targeted vibration, and gentle compression to relieve pain and keep you moving, naturally.

Support for Active Lifestyles

Whether you’re managing arthritis, recovering from strain, or warming up before exercise, ThermaFlex helps keep your body moving freely. Its combination of heat + vibration + compression prepares joints for activity and eases soreness afterwards. Stay active, confident, and in control — with a recovery tool built to support you through every step.

Targeted Heat Therapy

ThermaFlex delivers soothing heat directly to the joint, helping increase blood flow and relax tight muscles. As the area warms, stiffness begins to ease, allowing for smoother, more comfortable movement. This deep, penetrating heat therapy supports natural recovery and provides relief that can be felt within minutes — whether you're starting your morning or winding down after a long day.

Vibration Massage for Pain Relief

Gentle vibration works alongside the heat to stimulate circulation, loosen muscle tension, and reduce joint pressure. Instead of masking pain, ThermaFlex helps address the source of discomfort by encouraging the body’s natural healing response. The rhythmic massage effect offers a calming, restorative sensation that supports both mobility and relaxation.

Designed for Daily Comfort

With its soft reinforced wrap and adjustable straps, ThermaFlex comfortably fits knees, shoulders, and elbows without restricting movement. Use it while reading, watching TV, working at your desk, or preparing for activity. The lightweight, cordless design ensures you get relief without bulk or hassle — making it easy to use anytime, anywhere.
