It's a fleecy blanket with sleeves on the front, pockets for your snacks and remote control and a pocket at the bottom on the inside for your feet. Does keep you warm when you don't want to turn the heating up.I have to admit, I don't know what the definition of a slanket is. I have seen the word but never knew what it was. Obviously a cross between two words, one being blanket. Soft? Slouchy? Slutty? It'll be something obvious - put me out of my misery, someone.
