【Heat-Generating Material】This material absorbs the water vapor released from the body with highly absorbent rayon. The energy emitted by the moisture is converted into heat, causing the fabric itself to generate heat, making even thin pajamas warm. The image shows how the slight water vapor from the body turns into heat with Heattech. 【Easy-to-Wear Loungewear】Simple open-collar design, with nothing to hinder turning over in bed. The waist has a rubber belt design for easy on and off. Easy turning over can improve blood circulation and reduce stress from stimuli during sleep. 【Relaxed Fit】Compared to regular pajamas, these pajamas have a fluffy feel. They are also lightweight and use warm fabric. In addition, they are designed to be more relaxed than the standard type, so your back and stomach won't be exposed when you bend over or stretch. 【Heat Retention & Breathability】With high heat retention and breathability, this material feels soft and comfortable, even if you sweat. A staple item for autumn and winter loungewear! Static electricity is unlikely to occur, so those with sensitive skin can rest assured. Comfortable loungewear from autumn to early spring. 【Recommended Size】: 【SIZE:L】Recommended weight: 50-65kg, Height目安: 165-173cm * Hand wash or, if using a washing machine, we recommend using a net and the gentle cycle.
