About this product Color: Gray Size: 100*200 ＜Waterproof and Breathable＞ By using a polymer nano-material with pores larger than gas molecules but smaller than water molecules, we have achieved 100% waterproofness while also providing excellent breathability. You can use it comfortably even in summer without feeling stuffy. It also has excellent stain resistance, making it difficult to get dirty and easy to care for. Therefore, it is widely used for changing diapers for babies and young children, as well as for nursing care. ＜Comfortable Sleep＞ The side fabric uses 100% ultrafine polyester. Because soft materials are used, you can experience a comfortable sleep on the bed. The sheet has an all-around elastic band, so it securely wraps the mattress and won't slip even if you toss and turn. It is also easy to put on and take off, making it easy to change. ＜Easy Care＞ Washable at home and quick-drying. It doesn't fade after repeated washing, and because of the sturdy stitching, there's no need to worry about it losing its shape. ＜Size and Design Variety＞ It supports various bed sizes, such as double and queen.
