DFND Cooling Recovery Sleepwear Long Sleeve Shirt is powered by CELLIANT®, a blend of naturally occurring, thermo-reactive minerals embedded directly into the fabric.

These minerals capture body heat and convert it into full-spectrum infrared energy, which:

• Helps regulate body temperature so you stay cool, not hot
• Improves local circulation
• Increases cellular oxygenation

Unlike traditional heat-retaining materials, CELLIANT® works with your body’s natural thermal regulation—helping reduce overheating, one of the most common causes of disrupted and light sleep.

CELLIANT® is backed by 9 peer-reviewed clinical studies across fields including sleep medicine, human physiology, photobiology, and wound care.
