Warm knit quilt pajamas. The three-layer construction with inner padding provides excellent insulation! Despite being thick, it's incredibly stretchy, perfect for those days when you don't want to change clothes because it's cold. Easy to put on and take off, and the stylish Henley neck looks great on its own. Also ideal as a sweatshirt, loungewear, or homewear.

Polyester materials and fleece are warm when worn, but can feel stuffy from sweat during sleep, making it difficult to sleep and often leading to kicking off the covers. To create knit quilt pajamas, one of the representative warm winter pajamas, that are less prone to stuffiness and allow for a good night's sleep, the fabric and dyeing shops, in their first attempt, used nylon woolly yarn for the inner padding instead of polyester, which has moisture-absorbing properties and reduces stuffiness, resulting in warm three-layer knit quilts.

Rare nylon woolly yarn three-layer quilt, which reduces stuffiness, is almost unavailable in the market.
Knit quilt pajamas with excellent insulation often feel stuffy when the inner padding is polyester. Tsukuru Pajama's original design uses moisture-absorbing nylon for the inner padding, reducing this stuffiness and achieving high moisture absorption and release. It's the perfect material for pajamas that are warm but not stuffy. (Most of what is available on the market is polyester cotton, which is stable in terms of shape retention, shrinkage, and volume after washing.)

Perfect for pajamas! Thick yet highly stretchy! Pajamas that can be worn directly on the skin.
Winter pajamas can make changing clothes on cold winter mornings a hassle. On days with nothing planned, you might want to wear them all day long. Knit quilts with excellent stretch that don't hinder movement during sleep or daytime activities. Although the fabric is thick, it has excellent stretch, making it easy to move in and providing a soft, comfortable feel that you'll want to wear all the time.
