MUJI Cooling Sweat-Resistant Crew Neck Short Sleeve T-Shirt, M I am selling this because the size didn't fit. I only tried it on, but I have washed it once. It's difficult to tell the color from the photos, so please check the image from the HP (3rd photo). This material feels cool to the touch and is designed to be sweat-resistant. The cotton is organic cotton. 【Material】 The fabric has been treated to prevent sweat stains from showing on the surface. It features the natural texture of cotton while providing a cool and comfortable feel when worn. It is a blend of cotton and polyurethane, offering stretch. 【Design】 The stretchy material is used to create a compact fit. The design pays attention to detail, such as the width of the collar and the length of the sleeves, so it won't be visible as an undershirt. 【Specifications】 Transparency: Slightly sheer Stretch: Yes Fit: Slightly slim
