MUJI (Mujirushi Ryohin) Warm Cotton Wool High Neck Long Sleeve T-Shirt Color: Charcoal Gray Size: M Uses a yarn that blends cotton and wool. This functional innerwear is not itchy and is perfect for mid-winter. It contains no synthetic fibers, making it gentle on dry and atopic skin. The current product has less wool and costs 2990 yen, so this is a good deal. This warm innerwear enhances the "moisture-absorbing and heat-generating power" by applying special technology to organic cotton, converting steam emitted from the body into heat. This year, we've improved the materials to make it even warmer and more comfortable to wear. ■ Enhanced natural moisture-absorbing and heat-generating function of cotton Cotton is a natural functional material that absorbs moisture and generates heat. We have created moisture-absorbing and heat-generating innerwear that maintains the texture of cotton while further enhancing its original functions with special processing. The warmth lasts even after repeated washing. ■ Reduces skin dryness Compared to synthetic fiber materials, cotton does not excessively absorb the skin's oils, making it a gentle material for dry winter skin. ■ Combination of natural materials that suppress static electricity Synthetic fibers and different materials tend to generate static electricity. Cotton is less prone to static electricity, and it is a material that is less likely to generate static electricity even when layered with wool knitwear. ■ Features of Warm Cotton (Wool) To prevent warm air from escaping, we use hollow yarn with voids in the yarn, enhancing heat retention and creating a soft, fluffy feel. It can be worn as an outer layer or as an inner layer. This is a versatile piece that is useful during the peak of winter and for outdoor activities. Due to shipping costs, we plan to ship without the packaging. Although it is new and unused, please purchase it if you understand that it has been stored at home. Size...M
