Foam sleeping bag systems out perform Wiggy's or any other sleeping bag on the market.
The really nice custom bag you see here is made by a guy here in UT named John Arbon. He's the guy that made
Here is his website:
The site contains more info on the technology.
As far as I understand it weighs about 8 lbs
I sell a poor man's version of the bag. Here is a copy of the newsletter I sent out to my database of preparedness people.
Here is the Poor Man's Gear sleeping bag system
Image is attached below. I also included the image of the bag from the video
Essentially this is a tube that you slip into from the top. No zippers or manual closures.
These bags are designed for long term use, day in day out, even for months at a time if necessary. They will not retain moisture. The sleeping system, and you, will not freeze when used correctly.
* Heavy duty outside construction of wind resistant/water repellent Versatech like fabric
* Constructed with 1.5" soft foam for full arctic sleeping conditions
* Includes 1'' firm foam moisture handling pad and deicing clothe
* Draft curtain to trap dry stabilized air inside bag while in use
* Hooded top to provide maximum warmth and minimum exposure
Why Foam Sleeping Bags?
Most sleeping bags are made of a type of fiber batting sandwiched between some type of fabric envelope. Others use down for their insulation. The primary purpose of an insulation is to maintain a dead air space between you and the undesirable temperatures. The better an insulation can maintain that dead air space, the better the insulation.
Foam does a better job of maintaining a dead air space even when wet. Also, the very nature of it is hydrophobic (repels water), not hydrophilic (attracts water). This means that it does a better job of shedding the moisture that your body produces all the time. Yes, even when you sleep your body is expelling moisture. This moisture has to go somewhere. If the clothes you wear in your sleeping bag, or the material from which your bag is made is hydrophilic (attracts water), it will retain that moisture and in sub-freezing temperatures will cause you to be very cold, if not very dead. In relation to cold temperatures, "Cotton kills," is a saying that is used frequently to remind people that such a material is very undesirable under those conditions. Synthetic materials work best in shedding this moisture. Synthetic materials include, polyester, nylon, rayon, and other petroleum based products (oil and water don't mix).
Thus when using a foam sleeping bag system you really want to avoid sleeping in hydrophilic(attracts water) materials such a cotton/ploy long john, cotten sweats, t-shirts, or cotton based undergarments. These will only trap the moisture next to your skin and drop your body tempurature.
Fiber batting and down work very well for short-term use, and if that is all you need, then go do some research on these bags and get one of those (Wiggy's bags are excellent fiber bags), but over longer periods of constant use they will fail. With long-term consecutive day use moisture builds up over time in these materials and their ability to insulate is dramatically reduced; sometimes even in as short as three consecutive days.
Selecting your size
Girth is the distance around your body.Measure around waist/hips/shoulders in inches, select the largest of the three, and use that measurement to select the appropriate girth for your bag.
Height is simply how tall you are. For example if you are between 5'10" and 6'4" you'd select an XL.
Sizes and Prices:
* XL - Girth:58" - 62" Height (5'10" - 6'4") $380.00
* L - Girth:53" - 57" Height: (5'3" - 5'9") $370.00
* M - Girth:48" - 52" Height (4'8" - 5'2") $360.00
* S - Girth:43" - 47" Height (4'1" - 4'7") $350.00
Back then a nice bear or buffalo coat was nice to have...:thumb:Be a badass and cold weather camp with a wool blanket :
People did it though way back when...it took a steady fire though and a good shelter. You think the alaskan gold miners and pioneers had space age technology?
Thanks Doc, this was just the nudge I needed to go ahead and order one of these, which I just did from cheaper than dirt.I have found a much cheaper and reliable sleeping bag. It is the ECWS Modular Sleep System used by the army. I have spent many nights (18 months in Iraq) in this bag. It worked really well and never needed service. I have also used it in northern Wisconsin in the winter with no other shelter at -18 below. It is also much cheeper.
I have the package and I'm about to open it.Thanks Doc, this was just the nudge I needed to go ahead and order one of these, which I just did from cheaper than dirt.
True it is cheaper, but you get what you pay for.I have found a much cheaper and reliable sleeping bag. It is the ECWS Modular Sleep System used by the army.

Foam breaks down to UV exposure. If protected it will last a very long time. What does it take to protect it? Not much actually. Just encasing it in a shell works just fine. A person using it for clothing or a sleeping bag would do that anyway. Take the picture for example. The foam is encased in a layer of Versatech fabric, for an outside shell. This bag is ready for many years of heavy use.Not disputing anything posted about the bags...
My concern would be how does the foam react to sunlight, heat (desert camping gets hot), and time. I have some foam pads that started falling apart after a few years... would hate to invest in a new technology and have a boat anchor in a few years. If a major company (such as North Face) or retailer (such as REI) were backing it, my fears would be allayed, as they'd warranty it...
That's a great question. The bags are not waterproof. The outside fabric of the bag is 'water repellent'. Not the same thing. Yes the material used in the bag is hydrophobic. So with a breathable shell the hydrophobic insulation is free to push all the moisture the body generates to the outside air. While the 'water repellent' fabric has a tight enough weave that it turns away water molecules bunched together to the size of a rain drop. The tight weave also prevents wind from disturbing the dry stabilized air that acts as insulation.I have a question about foam bags...
They are waterproof and "hydrophobic", so how does your body breathe? If the bag will not absorb any water, does that mean that you wake up in the morning in a warm pool of your own sweat and other fluids? If not, why not?
