quick question, how do you keep all your sweat from pouring out of your VBshirt onto the inside of your bag when you sit up. I guess the same goes for a VBLiner. You must need to get out carefully to keep from getting your bag wet.
The idea with a VBL liner is *not* to sweat a lot in it. As for a VBL shirt, rick's not talking about wearing this in the bag - he's talking abou wearing it while walking in subzero.
Of course you have to be careful.
Also if its that cold that your body vapor can freeze in the down isn't it dangerous to unzip your bag and get out while wet at such low temps?
If this were the case Canada would have never had human occupation because their bladders would have burst as we all steadfastly refused to leave our sleeping bags/buffalo robes. (then again I know I've had mornings that felt like that <img src="/forums/images/graemlins/smile.gif" alt="" />
it's not like you're sitting in the bag soaking - the problem is not that you are dripping - the thing you have to remember is this isn't that you're wet, it's just the natural water vapor that comes off your skin that freezes. Think about when you are in a single wall tent - you're not wet, but there's a bunch of moisture on the inside condensed in the tent. A lot came from your breathing, but some came from water coming right off your skin. In really nasty cold, that water doesn't go up and condense on your tent, it condenses, then freezes,
inside the sleeping bag. and if it's down that can really suck. The VBL doens't leave you sweaty (or it shouldn't in a bag) It should leave you comfortable, not dripping.
and as for getting out - you can always get out in such weather - you just can sit outside naked and wet with no chance of getting dry and warm.
