DFND Infrared Recovery Sleepwear is embedded with CELLIANT® minerals, which absorb body heat and reflect it back to the wearer as Infrared energy. Infrared energy increases local circulation and improves cellular oxygenation, which promotes restful sleep, increases comfort, and regulates body temperature, which is one of the most common reasons people stay in light sleep. DFND Infrared Recovery Sleepwear will promote the body to rest and therefore increase deep and REM sleep, which are critical components for mind and body recovery.

It is recommended to wear both the Top and Bottom to get the most effectiveness. It is also recommended to use a wearable technology that measures your sleep to see the difference in your REM / Deep sleep.

CELLIANT® is the world leader in infrared responsive textiles and is a key ingredient that powers the revolutionary DFND Infrared Recovery Sleepwear. CELLIANT® is clinically proven to enhance tissue oxygen levels to help your body be at its best.

Made in the USA & Berry Compliant.

Male model is 6'2" 190lbs and is wearing a size large.
Female model is 5'8" 140lbs and is wearing a size small.

DFND Infrared Recovery Sleepwear is powered by CELLIANT®, a blend of natural, thermo-reactive minerals that gives any textile-based product the ability to capture and convert body heat into full-spectrum infrared energy, improving local circulation and cellular oxygenation.

Our scientists select safe, naturally occurring, thermo-reactive minerals for their unique properties, such as energy absorption and reflection. Backed by science and working rigorously to test and validate the science of infrared technology, Celliant® has had 9 peer reviewed published studies that demonstrate the effectiveness and benefits of infrared energy to date. This includes experts in the fields of photobiology, nanotechnology, sleep medicine, human physiology, diabetes and wound care.
