When looking at what is a sleeping bag liner, it is important to consider that the cocoon that the liner forms has the ability to insulate the user from heat loss or gain. The insulation is usually from polyethylene, which is also used in the construction of quilts and other items which require heat insulation. Other materials which may be used include goose or duck down. These are all good insulators, although it should be noted that each type has its own pros and cons.
A sleeping bag liner, which is thicker than other components may be able to provide greater amounts of insulation. It is advisable to choose a thicker lining as a result of the increased amount of warmth that the bag provides. The insulation would normally be between one and ten degrees Celsius although this varies considerably from manufacturer to manufacturer. When choosing a bag which has a thicker insulation, it is often better to opt for an all over body style instead of a top and bottom heavy style.

In effect what is a sleeping bag ends up being warmed through the trapping of air within the bag. What is a sleeping bag should instead be sealed to prevent the entry of moisture into the bag. In the worst case scenario this could lead to mould forming in the base of the bag.

A sleeping-bag liner which has been produced by means of a closed cell foam rather than open cell foam will provide a higher level of insulation. Another point to note is that sleeping bags with sealed insulating materials will usually cost more, but they are worth the money as the insulation is of a very high quality.
