If we’re talking about the same thing, I saw snuggies in Walmart just the other day. They “updated” the colors/designs .....
Actually, my mom got me one a couple of years ago. It is warmer than all but one (double) fleece blanket I have ... surprising, because the fabric isn’t all that thick. I don’t use the ‘arms’, just as a regular blanket .... and only in the house, not in public (it’s a really ugly pink).
Someone gave me one years ago with skull and crossbones on it. It turned into the dog’s blanket real quick. Lol
