These are a really good idea.
We use it both after swimming and also after bath time. After swimming it's helpful to be able to pop the child into this, especially if you are on your own, whilst you get dressed. You can be reassured that the child is staying fairly warm and snug in this. I would agree with another reviewer who mentioned that the product is better for children who are able to stand on their own.
We also use it after a bath to keep little one warm whilst we dry her hair, so that her hair doesn't then soak her clothes.
I hoped that this product would be a bit thicker and a bit fluffier, but overall it does do a really good job and we have used it a lot.
