    Is that what you all are talking about? I get lost in all that jargon talk. I have one of those. It's lite all right but bulky.

    There's 2 that Walmart sells; the thinner closed cell pad - sometimes sold as a "yoga" or work-out mat and the thicker pad that's egg-crated on one side.

    OK.

    Just pulled out my 73/74 EMS catalog. (The EMS catalogs from that era were very useful--half gear tutorial, half catalog.) It lists:
    * Beige Ensolite (the summer stuff: flexible to 0F)
    * Black Thermobar (flexible to -40F, appears to be similar to my green Ensolite)
    * Blue Volarafoam (flexible to -50F, my light blue stiff foam)

    Whatever... There have certainly be a variety of closed cell foam pads over the last few years (~1971--present, for me).

    Ive carried a survival blanket for years, very durable its silver on one side and red on the other, cant remember what its called but its bombproof. It has grommet holes to hang like a tarp, but My thought to survive out in the winter would be to 'dig in" and wrap myself in it. MY pack is not light in the winter. I carry full goretex upper and lower, patagonia r.5, retro-x jacket, heavy fleece pants, gloves (goretex ODR)3 hats ie,small beanie, heavy over the ears, full balacava and a patagonia guides jacket. Its alot, but I solo alot and feel the weights worth it to ensure long survival if need be. Ive been toying with the idea of a full bivi bag but havent made the move yet, I feel my tarp would be insufficient above treeline and a full bive would be better.

    I've been reading the various points of view with interest, and would offer this:

    For many years I carried heavy duty trashbags, and after helping evacuate someone saw how versatile the orange/silver tarps were in wrapping someone up on a litter (blankets underneath). But, the combined weight of the HD trashbags and sturdy tarp was beginning to add up. And, from experience with a poncho I knew that a tarp in windy conditions unless securely fastened wasn't very effective - and how do you secure it properly when you're inside it. And then there's the warmth factor - sure, an aluminized tarp reflects body heat, but there's little inherent insulation in a tarp. So, in some situations, particularly in winter, a sleeping bag is in order.

    When I saw the Blizzard Survival Bag I realized I could combine all the above functions into one entity that would do all of the above and weigh a fraction of the combined total. And, it's easy to tell whether it's in your pack.

    I always carry an emergency pad of some flavor in winter so that was a wash in terms of weight.

    So ... consider "cutting to the chase" and get a single solution which will cover all the bases.

    MSR E Bivvy

    I have an MSR E bivvy. It is about the size of a coke can. I haven't used it much but I slept out in it the first night I got it to try it. It rained. My sleeping bag and I stayed dry. It is a bit claustraphobic inside as there is nothing to keep it off your face when closed up. About 3/4 of the way up it is slit across from side to side(kind of like a pillow sham slit to get the pillow inside) so you can get your head in if cold or inclement weather. I supppose you could rig a way to get it off your face. I suspect on a warm summer night, like I tried it, that is more of an issue than it would be on a cold night. In that case I might be happy to just burrow into it. I was also able to roll it up to fit back in the stuff sack after using it. It takes up less space in my pack than one of those space blankets that come in the yellow stuff sacks. With whatever clothes I had on I think I could spend a reasonably sheltered night out. With a sleeping bag I'd be snug. It is pretty lightweight so I'm not sure how much prolonged use it would stand up to. But for an emergency I think it would do nicely.

    Here's what I carried last winter (Alex can fit into these with me).

    Black Diamond BiPod Bivy

    Western Mountaineering Puma sleeping bag (-25 degrees), packed in a compression sack

    In addition, I also carried multiple chemical hand and body warmers, plus those "emergency" bright-orange sacks you can pick up for $5.00 at REI.

    Also carried stormproof matches and stove, multiple layers of clothes, and a full-length closed foam pad.

    I've look at the yoga mat but it seemed heaver than the egg-crated mat.

    Is it just as warm?

    Is the blizzard a standard piece of reusable equipment or is it just for emergency use and does it make that space blanket wrinkly noise?

    Everything is reusable if you don't wreck it the first time you use it !

    I'd imagine most would probably replace it after use due to the packability and relatively low cost of a new one.

    After reviewing and weighing my gear and trying to imagine a real scenario, I started thinking the poles and fly from one of my 2 man tents might make sense to carry: Free Standing, relatively full coverage, light. Then I saw I could get the BA Seedhouse SL 1 for $200. I decided I could sell one of the 2 man tents and my Kelty Noahs Tarp that I never use for at least that much. So for about 4 1/2 lbs I can carry the SL1, an evazote pad and my old Northface bag cover. This would be for more serious winter outings as it is certainly over kill for an easy or average outing, but me or my injured partner would be pretty dang comfy, and I get a nice, light 1 man for the rest of the year.
