Sleeping bag of exterior insulation and lining contains elastic element between insulation and lining to expand and fill out user body space for snug sleeping.

摘要

The elastic or manually expandable element (4) is arranged between insulation (2) and lining (3) or is worked into the lining so when the interior contracts the insulation necessarily expands and so prevents any reduction in bag size. The element can be sited in waist and foot regions and consists of elastic threads in the stitches or again as elastic material forming the bag lining (3). The element can be formed by cord runs passing through tunnel stitches on the outside of the bag lining.
