Silk is a type of fabric that we naturally associate with luxury; we don’t usually think of it as something that will keep us warm! In fact, silk is a very poor conductor of heat, and consequently will trap warmth within the sleeping bag, making it a very warm option with a touch of luxury. 

Silk also has another surprising quality that makes this liner a must when you’re travelling in hotter climates. Its natural heat-managing characteristics keep the body at a comfortable temperature in both extremes of hot and cold.

Gram for gram this is our most heat efficient sleeping bag liner.
