Down is actually a pretty durable insulation, and if it is properly cared for will last much longer than any synthetic insulation. Some people use the same down sleeping bag for decades, but there are a lot of variables at play, and maintaining a down sleeping bag is a bit of an art form. When you buy a used down sleeping bag you will want to know: How ...

Leaves under your tent will offer almost no value as you will crush them when you lay in your tent. The primary benefit from leaves comes from dead air space. However they will provide a more smooth and soft sleeping surface. Leaves piled around your tent will provide good insulation as long as they do not get wet.

In my opinion two layers with say 60g/m² and 100g/m² are better than one with 160g/m². The different distribution of isolation is a point but I don't think this is relevant. You can get jackets with all kinds of stuffed torsos/arms/backs/arm-pits in lots thicknesses. The big advantage of the layering besides the versatility is the caught air between the ...

Using multiple layers has the benefit that you can take off only some of your insulation if you are getting too warm (for example, if you start hiking ...

If those leaves are dry when find them you can also put them under your matras with the same effect. I think it will work even better than putting them under the tent.

You would normally dress for the activity you're about to preform, and then add a watertight layer on top of your other layers. You also have to be certain that while the wet can't get to you from the outside, your poncho won't protect you against your on perspiration. As to address your direct question, you should insulate your head to protect against the ...
