Softi adult daipers Meduim

I have been buying the Softi Diapers for my 16 year old disabled son from then for years now and they now have changed the packing of the diapers but now the diapers is smaller first they did not believe me then with an old one I showed them and they then told me to buy the Large as I told them the large is way too big, I still am waiting for feedback no one can explain that and as they change the packing and diapers they now also are asking more for them.
