HH6 is out of the house so I managed to catch an episode of Bear's show Get Out Alive. It was a busy night on the scanner so I only managed to catch a couple of bits but the tip really stuck in my craw.
The tip was that you need to insulate yourself from the ground when you sleep.
Now that is great stuff but what they show next is some dude throwing out the ol'blue tarp and then throwing his WallyWorld sleeping bag on top and crawling in... This is unsat.
So here is my 1,000 words or less on sleeping on the ground,
Sleeping on the ground is awesome! I should add, if you know what you are doing.
In a perfect world you are all geared up and ready to go. That means ground pad, bivy bag and sleeping bag. That doesn't mean that you can't do without any one of those items. We will get into that after we discuss what is the difference between good and bad regarding those items.
Ground Pads
Why you need one?
The ground is cold, you won't heat it up... ever. You have a sleeping bag you say? Sleeping bags work on loft or simply put they work on the amount of air they can trap in their filler. What do you think happens when you put your body weight on that filler? That is right, you push the air out making it incapable of providing insulation.
There are a huge variety of ground pads, some are air filled but most are closed cell foam, some are short, others long, most are narrow and some are even cut to match your body, some are VERY expensive but rest assured most are very well priced.
I am going to admit that I don't have a much experience with the air fill variety after experiencing the old school ThermaRest 'self inflating' pad. The idea was that it had open cell foam enclosed in rubberized nylon. They were the cat's meow until you popped one or heaven forbid the damn thing lasted until the foam gave out and you had to blow it up! The reality was that they popped, like all the fucking time, they were heavy and worst of all they were cold.
You see, air has this ability to move heat. Typically that means away from you to something else that is colder. Our bodies are a typical 98.6 so everything is colder then us. They have attempted to combat this in the modern air pads by using foil to send that heat back. The new air pads are lighter, stronger and warmer... they are also way more expensive. Like starting at $150.. and that is a non starter for anyone but the most serious backpacker. I am going to get one, one day. In spite of my better judgment because I am getting older and the ground is getting harder.
What I have consistently rock is a closed cell Ensolite Pad,
While that isn't a photo of my pad it is about the same condition, I've been carrying it since I was 12. I've slept in the snow, mountains, meadows and even a parking lot filled with broken glass. They are light, easy to clean, cheap and if you can get one wet I'm interested to know how you did it.
Believe that for the money it is where it's at but don't get crazy and think that all blue pads are the same, sadly they are not. The ones they sell at WalMart suck a dick. The stuff they are made out of isn't tough enough and you can literally pop the individual air bubbles leaving you laying on a thin layer of whatever they are made of.
Currently you can get a USGI Ensolite pad with attached binding tape for $6-$15 at the local surplus store, they are fantastic... well they are thin but they are wider then most commercial pads and that is fantastic.
You might want two if you are getting old (like me), a side sleeper (like me) or are on snow.
The next step up is the Ridge Rest pad,
The idea is that they capture more air for less pad. I never weighed one against the other but I can tell you that the Ridge Rest was wore out and the old Ensolite was still rocking. Yes you read that right, I wore a Ridge Rest out.
There is something cool about the Ridge Rest, they are making them with a foil coating on one side. Totally good for sending the heat of the ground back at it (desert rat wisdom) or your own body heat back to you.
They also make some accordion folding shit... I got my Ridge right before they came out so I miss that trend. You still see them around and they are littering the shelves. Word to the wise, they tear where they fold.
Bivy Bags
WTF?
From Wiki
Bivouac SackA bivouac sack (also known as a bivy, bivvy, or bivi) is an extremely small, lightweight, waterproof shelter, and an alternative to traditional tent systems. It is used by climbers, mountaineers, hikers, ultralight backpackers, soldiers and minimalist campers.[1] The bivouac sack has a larger, similar counterpart, called a bivouac shelter.
Why you need one?
The ground is always wet, even in the desert. Wet gear is heavier then it needs to be and fails to insulate. Nuff said.
I don't have very much experience with bivy bags, I only recently got into using one after scoring a USGI model for $40.
I wanted to get away from tents and into something lighter weight that was also smaller. So far I have yet to be rained on in my bivy exclusively as I hide under trees when it gets shitty. It did snow 2' foot on me in it without any cover.. wasn't bad aside from having to kick around to keep the snow from building up, once I learned to put my boot next to my face to keep the cold wet gortex off my face.
I will tell you that this is one Gucci bit of kit if their is any interest I will do a full write up.
And that is enough for one night.
