With their relaxed, loose silhouette and ease of use, they have become a popular summer staple. Since there are no buttons, you can easily wear it by just slipping it over your head. It is easy to handle even for seniors and can be worn by a wide range of generations, so it is recommended for those who are new to pajamas. It is also convenient to wear after a sweaty summer bath. Since there are no small decorations such as collars, T-shirts are less likely to lose their shape, are easy to wash, and are easy to handle. Another appeal is that T-shirts look good even when worn out. For those who don’t like “typical pajamas” or who want to stay comfortable even on hot nights, T-shirt pajamas are definitely a recommended item. At Pajama Shop IZUMM, we offer T-shirt pajamas made with carefully selected materials to maximize the appeal of T-shirt pajamas, so they are perfect for a good night’s sleep. These summer pajamas, made possible only by a pajama specialty store, will be a staple for the coming summer.

Specially for summer! “Smart everyday wear for adults” that is so comfortable you’ll want to wear it every day Among those who prefer T-shirts for summer sleepwear, there are many who use the T-shirts they wear outside as pajamas. Make sure you wear something comfortable during your precious rest time. Pajamas come into direct contact with your skin every day. That’s why even the slightest difference can have a big impact on the depth of your sleep and your mood the next morning. Pajama Shop IZUMM’s T-shirt pajamas are made from
high-quality materials, making them an “investment” that will change the quality of your sleep. The result is a set of a T-shirt for sleeping made from extra-long cotton triple-ply yarn, and smooth gauze pants that stretch a little to fit your body comfortably. Furthermore, the smooth, silky sheen of the T-shirt and the smart, sleek (= slim and clever) silhouette of the pants create a sophisticated impression that makes them more like “smart everyday wear for adults” than pajamas. The boundary between pajamas and loungewear is ambiguous, so you can feel relaxed before going to bed or doing housework in the morning, but you can also feel like you’re not wearing pajamas. It’s also recommended for breakfast, reading, and doing a little work. You won’t have to worry about unexpected visitors or deliveries. 2. Smooth and soft, a special texture The top is “smooth” and the bottom is “soft”. The different skin comforts of the T-shirt and pants will envelop your entire body. The “sleep” T-shirt is made from rare extra-long staple cotton, which accounts for only 5% of the cotton produced in the world, and is made from three strands of yarn spun together into one using advanced technology. It feels like silk and has a beautiful luster that shines from the inside. One of the charms of “three-ply thread” is that it is not see-through and can be washed without worrying. The pants are smart room pants made of Pajama-ya IZUMM’s original fabric “Stretch double gauze “Nobbize (R)”. The part that touches the skin is 100% cotton, and the softness is unique and gentle to the touch. The highly absorbent gauze material with good breathability quickly absorbs summer night sweats. 3. You can move freely and turn over smoothly, so you wake up refreshed. On hot summer nights, when it’s difficult to sleep, you turn over in your sleep to regulate your body temperature. That’s why we made pajamas that are designed to be easy to move in. T-shirt-style pajamas fit your body well and there’s no need to worry about buttons getting in the way. This set of a T-shirt with armholes that allow you to move your arms easily and stretchy “Nobbize(R)” smart room pants will keep you comfortable all night without getting in the way of your turn over in your sleep. The pants in particular have a slight stretch due to the special thread structure, which reduces the feeling of tightness when you turn over in your sleep and makes it smooth to stretch when you wake up. It supports the quality of your sleep. A great gift for those looking for a higher-grade pair of pajamas or those who don’t usually wear pajamas

https://prcdn.freetls.fastly.net/release_image/59370/42/59370-42-7edb65adfb0c17fa209882da9d66e1c6-1000×650.jpg We, the pajama shop IZUMM, make “NERU FUKU(R)︎”, clothes for sleeping. “NERU FUKU(R)︎” is pajamas and clothing that use original fabrics that pursue a “touch” that appeals to the five senses that are important to humans, especially the “touch”, to ensure a comfortable sleep and a comfortable life. In addition, we are particular about creating designs that you will love wearing. The Great East Japan Earthquake on March 11, 2011 prompted us to reexamine what is required of “clothes to wear when sleeping.” “I sleep in my everyday clothes so that I can escape in the middle of the night if an earthquake occurs.” “I’m worried about people seeing me at the evacuation center, so I’m not good at wearing pajamas…” While people want to wear pajamas to get a good night’s sleep, they also hear the voices of people who can’t sleep in their pajamas because they think about what to do in the worst case scenario, and people who are too late to evacuate because they have to change from their pajamas into regular clothes. At the time, there was a real sense of anxiety about not knowing when a disaster would strike, and we thought it was important to be prepared for such an emergency. In response to this request, we created “clothes to wear when you sleep,” which was the beginning of “clothes you can wear and run away in case of an emergency = “If.” And now, 14 years have passed since the Great East Japan Earthquake, and what is needed in today’s world has changed. Disaster prevention awareness is always in our minds, and interest in health has increased after the COVID-19 pandemic. At the same time, the options for how to spend time at home and relax have increased. We are currently planning to expand our lineup of pajamas and clothing that are suited to this modern era, which we have named “NERU FUKU(R)︎”. The newly released “Men’s Short Sleeve T-Shirt Pajamas Rare Extra-Long Cotton Triple-Thread Top and Stretch Gauze Smart Pants” and “Women’s Short Sleeve T-Shirt Pajamas Rare Extra-Long Cotton Triple-Thread Top and Stretch Gauze Smart Pants” have joined the summer “NERU FUKU(R)︎” lineup. In recent years, the seasons have changed and people spend more time in light clothing. However, “what if” situations in terms of disaster prevention and each lifestyle can occur regardless of the season. Enjoy these pajamas as “NERU FUKU(R)︎” to cope with “what if” situations during the summer when you start wearing light clothing. We at Pajama Shop IZUMM will develop “NERU FUKU(R)︎” to fit all lifestyle patterns as clothes that allow you to sleep peacefully in both mind and body.
