My husband and I were looking for a foldable play pen that would fit all 3 of our dogs for when we travel. I got the large size and as you can see , my husband fits in it. It folds flat and even has its own carrying case. Folding it the first time was tricky but the we got the hang of it after several tries. 
It has pockets to store toys, treats, etc. it also has a mesh top to keep bugs out or to keep in those dogs that are good at jumping out. It’s just what we needed.
