Softest baby pjs? Like Kick Kee Pants

We have used Kick Kee Pants in the past for the newborn stage and I looooove how incredibly soft they are! They are just made well and the price reflects that…. Which means they are just too expensive to buy a ton of (I wouldn’t have this problem if I didn’t get rid of all of our baby items after my second child) 😩. So, what other options are out there with that super soft, stretchy feel for newborn zip ups, button ups, or gowns?

I don’t like fleece, and I don’t like any rough fabrics. Sometimes even 100% cotton can feel quite stiff. Any suggestions?
