Keeps you cool when it's hot and warm when it's cold. Temperature-regulating sleepwear. Outlast technology, developed for spacesuits, helps you stay comfortable despite temperature fluctuations during sleep. Outlast is an innovative temperature-regulating material made of microcapsules, 20-30 microns in diameter, incorporated into the fibers. The original fabric is a blend of absorbent cotton and highly moisture-wicking rayon, interwoven with durable, quick-drying polyester. It's a comfortable sweatshirt fabric with a soft, skin-friendly pile finish that resists wrinkles. Suitable for spring, autumn, and winter, and also for those who use air conditioning in the summer. The fabric is treated with environmentally friendly silver ion AG+ antibacterial and deodorizing processing. It prevents unpleasant sweat odors during sleep and is also effective against indoor drying odors. Furthermore, its effectiveness is recognized even after approximately 100 washes. *Can be washed in a drum-type washing machine, but do not use a dryer. Unisex size, suitable for all genders, ages, and body types. There may be damage to the outer bag. Please understand.
