Fabric: 12 Ann and 100% cotton canvas thick, not the thin one. The effect of matching sweaters and coats in autumn and winter is very nice. It's not too much to say in spring and summer. It's easy to match whatever you want. About fading: the reactive dyeing technology used in the bag canvas fabric has been controlled to the best, and the color fastness will not fade when you back, even when you clean it, it is only slightly floating. However, when washing, you should wash the reverse side gently. Remember not to rub the printed pattern directly to prevent the pattern from fading.
