This is HOT! The Selk'bags are essentially a sleeping bag shaped like a person so you can move around with it on. Much better than hopping around the house in your sleeping bag because its super cold. Great for all sorts of cold weather. Wearing this around the house could also really help you to reduce your heating bill. I need this for my lazy weekends.
The Selk'bag is not just any old sleeping bag with movable arms and legs, it is made from premium insulating materials, meaning that you'll be running about in complete warmth in almost any weather the UK climate can throw at you.
