I love these. I bought these since I started potty training my daughter not so long ago. I love these over her big girl undies instead of pull-ups way better. I actually have washed these a few times in the washer and dried them. So far no problems but I wouldn't recommend doing that a lot.
I bought my daughter the 2t which fit now but not sure how long. I'm hoping at least a few more months. Anyways I kinda wish I had gotten a 3t. I just pull them lower on her legs so they aren't tight. In the picture with her brother the pants actually helped keep the pee in. I think they are just as good as any others I have used before. I'm just so happy I got them. The messes I would have been cleaning the first day would have been crazy. So yeah very happy to have them.

I added a picture of size 2T training pants and 2T plastic ones.
