Wear Cool uses Brain Sleep's unique fabric that absorbs moisture and sweat to lower the surface temperature and effectively provides a cooling sensation, in addition to the "contact cooling" that feels cool from the moment you put it on so that you can stay comfortable even in the rising temperatures and the hot weather that is becoming longer. It is the ultimate cool product to prepare the sleeping environment for the summer of 2024, when extreme heat is predicted. Summer sleep challenges The year 2023 will see record high temperatures all over the world, with Japan's average temperature reaching its highest since statistics began in 1989, and the number of midsummer days and scorching hot days across the country reaching a record high. *1 In 2024, which is predicted to be even hotter than this year, summer days were observed in over 100 locations across the country as of March, and the Japan Meteorological Agency's three-month forecast for June also predicts that temperatures will be higher than average nationwide. *2 In Japan, people tend to sleep less than other countries, but in summer, people wake up earlier in proportion to the earlier sunrise, which makes it even easier for people to get less sleep.The hot and humid weather also makes it difficult to fall asleep, and people tend to wake up in the middle of the night, making it a season in which the quality of sleep can decline. On the other hand, rising prices and rising electricity bills due to the end of subsidies have also become social issues, placing a financial burden on households, and the demand for heat countermeasures that do not rely on electricity is increasing. Brain Sleep has developed Wear Cool to provide high-quality sleep that can withstand the heat. Make good use of cool products and get a high-quality sleep to survive the scorching heat. *1 Japan Meteorological Agency "Climate Change Monitoring Report 2023" *2 Japan Meteorological Agency "3-month forecast (announced May 21, 2024)" (For the development background, please see the past release https://prtimes.jp/main/html/rd/p/000000196.000046684.html.)

Features of "Brain Sleep Wear Perfect Cool" 1. PERFECT COOL : The ultimate dual cooling technology of cooling to the touch and moisture absorption provides a cooling effect of 260%! The highest level of cooling sensation that you can feel the coolness from the moment you put it on. To achieve the ultimate cooling sensation, we used cooling nylon for the core of the thread and polyethylene with even higher cooling sensation for the periphery, developed ultra-fine threads consisting of about 100 fibers, and developed a unique fabric by weaving the ultra-fine threads with nylon threads and polyurethane threads using a special technique. By adopting this uniquely developed fabric, we achieved the ultimate cooling sensation with a cooling sensation value of 0.524 (a value that indicates the amount of heat transferred from the body to the fabric; the higher the value, the cooler it feels) that is about 260% higher than the standard value of 0.2 (which is just slightly cool to the touch). The ultimate moisture absorption cooling sensation of up to -7.7℃ when damp while you sleep. Our uniquely developed cooling fabric has been further processed with an innovative moisture-wicking cooling effect. As a result, it absorbs moisture and sweat that occurs during sleep, lowering the surface temperature and effectively cooling the body. The cooling effect has been confirmed even after 50 washes. * Cooling sensation value of approximately 260% of the standard 0.2 of cooling sensation (q-max: W/cm2) 2.SUPER CLEAN : Antibacterial and deodorizing treatment keeps you clean every day, even in summer. Its antibacterial and deodorizing function is 2.5 times higher than the standard antibacterial activity value (2.2), preventing the proliferation of bacteria in the summer. Its effectiveness remains unchanged even after 10 washes. (Antibacterial activity value: reduction rate of Staphylococcus aureus) 3. RELAX & COMFORT : Stress-free with two-layer fabric The skin side is made of a cool fabric with a smooth texture and water absorption/diffusion properties, while the surface is made of 100% highly absorbent cotton fabric, making it gentle on the skin and designed to eliminate stuffiness. Eliminates the unpleasant stuffiness while sleeping. The combination of highly absorbent and hygroscopic materials absorbs and releases moisture that inhibits comfortable sleep, effectively regulating humidity so that you can stay comfortable even when you sweat. The design is comfortable and does not restrict the body, supporting sleep. This sleepwear reduces stress by maintaining a comfortable range of motion, with larger armholes and no excessive tightness from elastic or ribbing, to ensure comfort when relaxing before falling asleep and to allow you to turn over during your sleep.
