I dunno... they look plastic backed to me. Going through the thread on Bsky there's no specific info other than only large will be available at initial release. That's targeted for after Anthrocon. They say medium and XL later this year. And Little Troubles is also releasing their own diaper .... TOO MANY CHOICES!!!!
ok.... this picture sure does look more like cloth-back. BUUUUUTTT...... right from their own posting. It's plastic back w/ texture. Honestly. I'm not a fan of that either. For me, the super buttery-smooth plastic is what really gets me. However, I'm still gonna buy some cuz I'm a sucker for something new. When they come out in XL of course.
