Since the organic fabric is undyed, how does it do when it gets soiled?

Since it's 100% cotton, it can be washed and dried like regular clothes.  The fabric is also pretty thick, so it will hold up to whatever your little one can dish out.  If you're a mom, you definitely need a stain stick on hand! Customers use their organic HugaMonkey sling nearly every day for over a year, and they still look great.
