sleeping bags 

seasons explained

sleeping bags usually have a classification dependent upon the season with Spring, Summer, Autumn and Winter but there is also an additional classification of Expedition. There is no industry standard and as a result interpretation of these classifications can and does vary between manufacturers.

The classification does however come with a temperature guide as well and the table below shows the minimum temperatures the sleeping bags are designed to be use at. 

The classifications do not and can not however cover all situations as we all know that the vagaries of the weather across Europe can at times lead to extremes.

The next step up is a double quilted or stitched layer where the stitching is offset to reduce the problem of cold lines.

The majority of synthetic fill sleeping bags use hollow threads trapping more air to warm up and reducing the overall weight of the bag.
