Featherlight, silky-smooth, and exceptionally breathable, the CoolLife sleep set provides a completely unique level of comfort. By releasing 100% of your body heat, our special fabric continuously cools your body throughout the night to give you the best rest possible. Our tank and short combination is ideal for sleepers who prefer a little skin contact, and doubles as pretty loungewear.

According to scientists, to fall and stay asleep, the body’s core temperature needs to drop by 1°C, or 2° to 3°F. This process induces sleep more quickly, and increases deep sleep by 10–20% (that’s the non-REM, slow-wave sleep in which brain waves slow dramatically and your body heals physically, recovers from illness, and deals with stress). Our CoolLife Sleep tech continuously cools your body by 1.8C/3.3F (19%) more than Dagsmejan Nattcool Sleep Tech T-shirt, thermoregulating your temperature throughout the night to deliver deep sleep, which is the very basis of wellness in waking life.
