My sleep system

Fleece Blanket - Fleece is very light weight, can be ringed-out if wet, dries very quickly, and remains a good insulation layer even when damp or wet. One should have a blanket large enough to cover two people or to fold over and double the insulation for a singer person. There should also be enough blankets for everyone in your party to have their own.

Sleeping Bag - Absolutely on the top for importance (next to pack and shoes). This is another item I see totally absent from so many 'bug-out-bags' shown or listed on-line. I just can't understand how these people think they could survive sleeping on the cold ground (in any season) maybe relying solely on a large camp fire for warmth (a very stupid idea that could lead raiders to your camp, start a massive forest fire, and burn up all your fuel). Just use a sleeping bag! I use a Canadian goose down mummy bad. A bit expensive but it compacts to about the size of a football, is rated for zero degrees. Because I tend to use my sleeping bag as a blanket I generally buy one that is one to two sizes 'too large'.

Sleeping Pad - After a single night on the hard cold ground, everyone will wish they had anything softer and warmer. A simple ground pad can be the difference between sleep and misery. I like the Therma-rest z-lite folding sleeping pad. I use one that is slightly longer than what I need so I can fold up the excess and use it as a pillow. I keep mine strapped to the outside of my pack for quick and easy access so I can have a comfortable seat without unpacking my bag. And I can fold it back up strap it on an leave in seconds.
