Sleeping bags are great, but they aren't once you've got snuggled in and then realise that you've got to get out of it again, that is until the Selk Bag was invented.

In what has to be the craziest looking sleeping bag of all time, the Selk Bag is a sleeping bag that features arms and legs meaning you can get up and walk around as normal.

Instead of wrapping you up in a cocoon the Selk Bag, which can keep you warm in temperatures as low as minus 10 degrees even has zips in the hands so you can make a cuppa without getting out of bed.

Designed to appeal to campers and students not wanting to pay the heating bill, the Selk Bag will cost £99 when it launches in the coming weeks. It is available from or for short.
