So, the Snuggy is a very cheap knock-off of a Slanket, which is the knock-off of the original Freedom Blanket, which was designed for elderly folks and disabled folks to fully cover everything (most robes aren’t long enough to cover your feet and ankles) and still provide mobility. I only know all of this because I’m suffering from a permanent illness that makes me extremely cold for no reason on and off all fucking day, and wanted to ask for one for the holidays. That led me down the rabbit hole about why to not get a Snuggy (they are cheap and thin), and I found this (among other articles explaining that some of the “As Seen on TV” products are for the aformentioned groups with mobility issues): https://gizmodo.com/ultimate-battle-the-snuggie-vs-slanket-vs-freedom-bl-5190557
