Just like the title says.
From 20 to about -40 F, are there any viable alternatives to using a sleeping bag?
I was reading up on Surplus color weather gear and someone was saying that the Lv7 ECWCS trousers and jacket could be worn instead of using a sleeping bag because they are rated to -40. Theoretically this would allow you to get up and see what that dump was quicker, and they pack smaller than most comparably warm sleeping bags.
-this is assuming you are sleeping in a 4 season tent, with a reflective space blanket beneath you to bounce your heat back on you.-
Picture is the suit in question. It is over sized, so even if it gets really bad or if it doesn't work as well as it says, I could layer up.
This stuff looks pretty hardcore:
Their normal stuff is -30F rated and their extreme stuff is up to -68F
That's actually a pretty nice sounding idea, considering I usually have to get up like 5 times when doing overnights.
Maybe not what you're looking for, but it's still a cool alternative.
You have to be extremely careful about wearing clothing while sleeping in very cold conditions. It is very easy to cut off circulation while you are sleeping and have very bad frostbite set in. Something as simple as socks that are a bit too tight can do this and you can end up losing toes. This can happen even in -40 equipment simply because there's nothing heating it when the circulation is too low or cut off.
I'm not joking about this shit either.
The level 7 stuff is rated basically the same as their entry level, and can be had for a fraction. I'm not honestly going to see -40, maybe like -20 if it gets BAYUD.
But would YOU consider the idea of wearing the puff suit instead of a bag as a grounded one?
Exactly. The "bump" always makes me have to pee, and the process seems to always be 10 minutes. I'd rather just stand up, waddle out and go than have to loose all warmth by getting out of my bag.
My biggest concern is loosing heat, or how effective these items are at sealing it in.
The ECWCS l7 stuff is designed to go over the soldiers standard clothes (along with the other base layers) and armor, so since I won't be wearing a flack nor the armored diaper (it's a thing) I should be good, I think. If I get the chance to try on a puff suit I'll take it. Thank you for the heads up.
i do like the coat
but in place of a bag is a bad idea see
you don't wanna mess with stuff like that, depending on the circumstance you may not even wake up before you lose something
i have a -10 degree mountain bag that i pair with a thermal liner and while getting up to piss is a bitch sometimes, as well as that first morning shit, id still rather have my bag than a puff suit
I've got a -15 bag, and I sleep in thermals.
This is while I am on a solid foam pad, over a reflective space blanket. I stay warm lol
Now this is for both the jacket and the trousers. All I would need afterwards is to cover up my hands and head for -40 (my over boot will be under the elastic at the bottom of the pant leg, allowing for better warmth)
The thing is, what are you trying to gain? You couldn't walk in those clothes because you'll simply end up boiling yourself inside them. So you end up carrying them in your pack, like a sleeping bag...
No, but at night you'll be better off with a sleeping bag because it's more efficient, it has way less temperature loss surface, and will be a lot lighter and less bulky. Also I'm pretty sure these temperature ratings are for use while awake (body burns more calories), and i've found that military gear temperature rates are much exaggerated anyways.
>with a reflective space blanket beneath you to bounce your heat back on you.-
When did this meme start? A space blanket will not insulate you from the cold embrace of mother earth. You better get some form of proper insulation to sleep on.
Protip: a closed cell foam pad can be had for under $10US and only weighs a couple of ounces.
The list as it has been stated before.
Tent bottom, space blanket, closed cell foam pad, then sleeping bag.
Currently just talking about replacing the sleeping bag, not the rest of the set up.
"Space blankets" are aluminium coated Mylar. They only reflect radiant heat, and are thermally conductive, not insulative. This means that if you put one under you or lay it directly on your skin, it will make you colder because it acts as a heatsink. The one and only time these pieces of shit are even remotely effective at keeping you warm is when they're suspended above you, either on top of a sleeping bag or as a lean-to/reflector if you sleep next to a fire.
A Puff Suit plus a goretex Bivy bag works great if you remember to bring a couple of extra things:
1- extra socks to be used only for sleeping (wool or synthetic only obv)
2- fleece booties to go over the socks (sometimes available being sold as indoor wear aka "slipper socks")
If you simply can't get hold of fleece booties, bring a second set of thick woolen socks in a larger size.
Never wear your boots laced up when sleeping like this, but do bring them into the bivy with you so they stay dry.
>have to get up like 5 times when doing overnights
umm, you might want to see a doc about that. seriously.
>what is a gatorade bottle
Not him, but I'm not carrying a piss bottle when I can basically pee wherever and whenever I want, which is one of the greatest privileges a man can have. Absolutely out of the question.
Though you're right on the doctor thing.
>Not unzipping the tent door, getting on your knees and letting out a powerful, steaming jet
>The urine lands 3 meters away
>The jet glistens gloriously in the night
>You or the tent interior are untouched by rain
In cold weather that can be a product of vasoconstriction. One thing that seems to work... dunno why, but I found out about it, tried it, and it seemed to work... eat a Snickers before bed. Like one of the little fun size ones.
>zoom in on the picture
>this text pops up
I am him. I don't have to piss that much actually. I have to get up a stupid amount of times because I'm always on the edge of freezing to death, and often the only way to remedy the bone chilling cold is to get the fire back going.
I actually rarely even piss considering I'm always in a constant state of dehydration because I live in Southern California.
