Definitely thinking of getting one of these..what is the difference between the two sold on Forge Survival Supply though? I see that the updated one is heavier and mentions a "Thermo-Lite" material, but I'm just wondering how much different it is than the original and if it's the only difference between the two. Thanks!

my BOB has several contractor garbage bags in it. They are very multi-functional. They can be used as bedding as stated above, split the seams and they can be used for a tarp, two arm slits and one for the head=poncho, drop BOB into it for water obstical fording, inflate it and and tie it off and “voila” floatation device and on and on.

Love the idea! Feedbacks is great. I think I’ll be getting some for both of my trucks and a couple for BOB as well.

Tried one of a different brand in Scandinavian winter – At night the temperature got as low as -30 degrees Celsius (about -20 degrees F I think). The bivouac acts as a vapour barrier, traps your sweat, it condensates on cold surface of the bivouac, the moisture was sucked by my down-filled sleeping bag and froze.

I woke up after half an hour shivering with cold, with my sleeping bag soaking wet and frozen to the bivouac. Spent the rest of the night sandwiched between the two others in our group wearing everybody's spare clothes.

So not really useful in a really cold environment. A space blanket or two are better there, because you can't wrap them so well around you, there will always be ways for the vapour to escape.

So only use them in moderate to cool temperatures, never in really cold temperatures.

Last night my wife and took a group of friends out on a steath bug-out overnighter. It dropped to around +40 and my friends had no sleeping bags, warm clothes, or blankets. I sacrificed my wool blanket, heavy duty reflective blanket, wool vest, and cap to try and help the three of them. I then filled my contractor bag with dry leaves, hung a tarp, and crawled into my down sleeping bag. I slept wonderfully.

Glad to see the site back up,missed the great articles. Actually tested one Heatsheet bivy bags on Boy Scout Wilderness Survival merit badge campout this past October,Southeastern region. Temperature approx. 45 degrees, clear skies, wind < 5 mph.Slept uncovered on the ground with just the bivy bag as shelter. Used an Italian wool Blanket as a ground pad (no sleeping bags or foam ground pads were allowed). Bag kept me plenty warm; problem was moisture accumulation inside the bag from my perspiration. Had to keep wiping it off the inside of the bag with my bandana all night. Great piece of kit, just be prepared to deal with moisture if you include it your gear. Could be critical issue in really cold weather.

This may be a little off subject but I read on another survival site to have a carpenter garbage bag (55 gallon). They weigh practically nothing nor take up space but that of a garbage bag. You fill them with leaves etc. and you have a pretty soft, dry way to sleep instead of the cold, hard ground. I bought a carton of 18 bags at Wal-Mart for around $20.00. I put 1 in my bag and 2 in my husband’s bag. It is a light bed roll in our grab bags. Love this site! Thanks Lucas.

I'm using a fleece sleeping bag, and in all practice runs it has been fine up to 0 degrees F when used with a tarp. If you leave an extra layer on it would probably do better. Also it weight is less than a pound, but its disadvantage is it is a little bulky when you strap it in to a rack, and it isn't waterproof by itself.

my down filled cold weather sleeping bag has a older style canvas bivi on it if you treat that with some water repelant it is a great bivi I like it because of the OD green it blends in well with the foliage around my area so i just slip into it and role under a bush and walla no one can find you unless they are looking for you that is.
