These are bedwetting pants (onepon). They have a polar bear pattern and are size XL for ages 4-6. These are the type with an adjustable waist and do not have elastic at the ankles. I purchased them on Rakuten and used them about 2-3 times, but there were no bedwetting incidents. They are machine washable. They are 100% cotton and feel good against the skin. How about these for a spare pair or for those struggling with potty training?
