After having this same model a few times we are suddenly not happy at all with the quality.  It seems that both the pairs we bought this year have a hard time removing the liner.  It seems they must have changed something about the way they are making them?  We used to be able to easily remove the liner to clean them in the wash.  Now you break a rivet when you pull them apart.  We followed the directions to how to remove but they cannot be removed without damaging them rivets.  Hopefully another manufacturer will come up with an alternative or they will go back to the old way of making them again.

I contacted the manufacturer and they said the rivets are backordered.  That was a long time ago.  The kids will outgrow them before they get to us.

Don't buy these!
