The “Selk bag” might look like an adult sized romper-suit but I can see the logic. Ever tried getting into / out of a sleeping bag in the middle of the night? For that matter have you ever woken up on a cold winter’s morning and wondered how you’re going to get out of the bag and into your clothes without important body parts icing up in the process?

Easy solution - cut the sleeping bag into a person shape and wear it! Personally I’d rather avoid the need and stay in a hotel but if you’re the hardy outdoors type this should be right up your street. Picture (and product) courtesy of IWOOT.co.uk
