Far Infrared Long Underwear / Long Johns

Our far infrared long underwear (long johns) not only keep the body warm on a cold day but can also reduce muscle fatigue, help relieve pain, improve circulation, and quiet restless leg syndrome.

ThermoFlow® long johns are made using a nano-technological process that incorporates fine ceramic particles in the polypropylene thread used to weave the light weight fabric used.

ThermoFlow® long underwear has been found to:

• Provide a feeling of overall warmth in cold temperatures without inducing sweat.
• Improve circulation in the legs, thighs and hips.
• Relieve stiff muscles such as tight hamstrings, calves or glutes.
• Aid in recovery of strained quadriceps, pulled hips, or cramped stomach muscles.
• Reduce swelling during sports like hockey, skiing, running, or personal workouts.
• Extend muscular endurance and performance.
• Alleviate pain associated with rheumatism, arthritis, and bursitis in the hip joint.
• Reduce night-time leg and hip cramping, muscles spasms, and restless leg syndrome.

Wear ThermoFlow® long johns under workout gear, during winter activities, or as pyjamas at night.
