Synthetic Sleeping Bags

Synthetic sleeping bags have come a long way since they were first introduced over fifty years ago. Advancements in synthetic yarn technology means a lot of these new man-made fillings are now comparable in warmth to down, as well as having other advantages. For a start, synthetic sleeping bags perform much better in damp and wet conditions. Being basically made from plastics, the insulation absorbs very little moisture, and the structure does not collapse when waterlogged. This means they will work in the wettest of conditions, and dry quickly as well. Unlike natural products such as down, these synthetic fillings are naturally hypoallergenic and odour free, which are important to some people.

The main disadvantages of synthetic sleeping bags compared to down sleeping bags is they are a lot heavier for the same warmth rating and a lot bulkier due to the lower compression rates.
