Synthetic insulation

Sleeping bags that have synthetic insulation are composed of poly-fibers, instead of animal feathers. It is easy cleaning such bags, and they’re cheap too. They work well in humid and wet conditions because they retain heat when they’re wet—unlike down bags that have untreated down. They also do not need so much care, and you can store them with ease.


The sleeping bag you’ll buy depends on its insulation capacity. But the face fabric is what protects the insulation, so the fabric is of great importance.


If you’re going hiking, then the packed weight plays a significant role. Having a lightweight sleeping bag adds only an extra weight to what you have already for your traveling or hiking adventure.
