New, unused item Reference price: 5,980 yen Color: Charcoal Size: LL Material composition: HeiQ SmartTemp processed material, a temperature-regulating technology from Switzerland Washing instructions: Machine washable [Temperature-regulating roomwear from a bedding brand that adapts to temperature changes] It's not just mattresses and pillows that affect sleep quality. Pajamas are also an important part of creating a comfortable sleep environment. This product is treated with HeiQ Smart Temp, a technology from Switzerland, and the fibers themselves respond to skin temperature. It releases heat when it's hot and retains warmth when it's cold, preventing you from waking up due to temperature fluctuations during the night and supporting comfortable sleep until morning. [Temperature-regulating design for all seasons] Designed for all seasons, it can handle the temperature differences of spring and autumn, as well as the hot summers and cold winters. It reduces sleep disturbances such as "waking up because it's hot" or "having to pull the covers back up because it's cold" during the night, leading to deeper sleep. It's also ideal for those who want to simply improve their sleep environment, reducing the hassle of changing bedding every season. [Comfortable sweat management with a cotton blend and quick-drying properties] Uses a soft, skin-friendly cotton blend material. It has excellent sweat-absorbency and quick-drying properties, quickly processing sweat produced during sleep and reducing stickiness and stuffiness. It also has breathability and stretch, making it comfortable in the summer and even when layering in the winter. With the double effect of processing and material, it provides stable comfort throughout the night. [Unisex and simple design] Although made with men's dimensions, it's a unisex design that can be used by anyone regardless of gender. The front button design makes it easy to put on and take off, and it's also easy to put on or take off to adjust the temperature. The simple and calm design naturally blends into the atmosphere of the bedroom, and couples can also use them as a pair. As a bedding brand, it's roomwear that supports sleep.
