This item features a soft touch, designed with comfort in mind, eliminating side seams. The cotton is organic. 【Materials】 From this season, the yarn thickness has been made finer, and the number of threads woven has been increased, resulting in a delicate and comfortable fabric. Furthermore, by changing from product washing to air tumbler processing, we have achieved a soft and fluffy texture while also reducing water usage by 1 liter per item. This has resulted in a product that is good for both the wearer and the environment. 【Design】 The design is a 2-way style, with buttons all the way up to the collar, allowing you to adjust the opening according to the temperature or your mood. The contrasting piping adds an accent, combining design and comfort, with a focus on sleep. The waist is fully elastic with an adjustment opening, allowing for adjustment by pulling out the elastic and sewing it in place. The elastic is not fixed, so it can be replaced. 【Specifications】 Transparency: Slightly sheer Fabric thickness: Thin Fit: Relaxed Waist: Full elastic (with adjustment opening)
