Until now, I was particular about “100% cotton bath mats”. But when they get wet, they become heavy, so I thought the washing machine must be using a lot of power (and electricity). When the weather is overcast, cotton doesn't dry very quickly... I was thinking this when I came across this product at Nitori. I was a bit resistant to polyester, but when I touched it, it felt smooth, so I bought it to try it out. The texture is no different to cotton, it feels smooth, it absorbs water well, and it's comfortable. After washing, it dries quickly, which is a big help. I plan to get a few of these and use them around the house.
