But my dilemma is: if insensible perspiration, assuming I vent or take out levels as required to prevent in excess of heating and outright sweat, continues unabated and regardless of human body temp of humidity within the pores and skin, why don’t I wake in the pool of liquid after 8 several hours within a VB? Or why don’t I get soaked in sweat while sitting all over at area temp, or a little bit down below, or exterior inside the 60s?
e. the tiny quantity of dampness Your entire body places out 24/7 even if we're not above heating, and which we do not even observe. but nonetheless can make it’s way slowly but definitely into our insulation. where by we hope it keeps on experiencing our breathable layers into the air, but where it occasionally hits a cold spot and condenses into liquid. Your example for all of that- even at 18 down below – is a fantastic instructing point.
This assumes that your perspiration doesn’t hit the dew position as it really is passing throughout the bag, during which circumstance it's going to condense on to the insulation or perhaps the shell cloth. Fabrics that breathe therefore, even at a restricted rate, never functionality as vapor barrier liners. A VBL fabric performs more like the 30D silnylon you might be intending to use for a flooring — it's waterproof although not breathable.
really thin urethane movies are astonishingly resilient and puncture resistant, also. Perhaps a great VBL might be made with these versatile resources in a few areas and common shelter fabrics in Other folks?
At least the down i spend money on this small venture can always be recycled into anything basically useable.
what about utilizing a Area blanket being a liner for sleeping bag? There is achievable to purchase it to be a sack. it is rather light. If needed, working with lightweight pack tape, you are able to built-in some wire for tightening close to a neck.
five mm shirt and trousers like a base layer for my occasional alpine skiing outing. I just want to remain warm but not bulky and am used to the clammy emotion of the wetsuit. For your a lot more demanding desires I can see how a shirt and trousers blend would bring about perspiration to escape amongst trousers and shirt rather than be a whole barrier. The shirt should also have a zipper to frequent warmth considering the fact that more info wetsuits are certainly economical with warmth and moisture retention. I'd personally also have to ensure that the seams are entirely water proof for that 1-one.5 mm fits. Fur my skiing demands, it will not be so significant.
Over-all, I believe the quantity of moisture is trivial, and it has a tendency to frost up on the exterior of your respective parka and sleeping bag, rendering it simple to wipe off.
By carrying VBL levels skiers could steer clear of the compromising of their insulation as well as sucking of heat from their bodies by this trapped moisture, permitting them to catch yet another elevate at 4pm.
I try to remember Listening to regarding your epic trek across Northern Minnesota. I think I had been winter tenting while in the Boundary Waters across the time you were passing by way of.
Andrew Skurka on December 28, 2022 at five:36 pm I normally buy the Altitude liner, since it’s not Substantially more expensive or heavier than another variations, because it provides you with the option to go reduced compared to the Other folks, and since there’s an easy Resolution whenever you don’t will need this type of heat liner (you are taking off the gloves and clip them into a carabiner on your shoulder strap).
I think it is a really exciting topic mainly because it looks unresolved and in many cases Possibly subjective rather then scientific… since;
initial, many thanks for your time and effort investigating, experimenting, and publishing your conclusions. I'm new to mountaineering, two several years, and portion hiking the AT. I appear to be gravitating to off-time climbing keeping away from the crowds. I hiked the first weekend in March at close to 1500′ in sleet and slept within a 30 degree down bag, REI Bivy, with my synthetic base layer and wakened three:00 in the morning mainly because I used to be moist and really chilly. The bag was wet on the surface, my foundation layer was damp on my skin and inside of the bivy was slippery moist. The good news is, I had been in close proximity to a town and was ready to make it into a laundromat and dry all the things that morning. past year, I hiked Vermont for each week in late August beneath wet ailments, ft had been moist The full time but was wearing wool socks and I never felt unpleasant.
But even just before these recent experiments, I very first begun employing Patagonia VB socks from the early 80s, and considering that 2006 I are using the Hennessy Hammock Super Shelter(HHSS), which contains a water resistant sil-nylon OUTER shell/underneath protect, and a few insulation for example an open up mobile foam (aka sponge!) pad and what ever else I'd add in the middle, combined with an affordable two oz House blanket(SB) – a radiant block supposedly- that goes in between me and all of the insulation, and which serves to be a vapor barrier. Or from time to time VB garments. Though the SB is not really an excellent VB because it could allow for some dampness to drip down the aspect in the hammock, because it simply just lays along with the pad under the hammock, it's carried out a high-quality career of keeping the OCF pad and any additional insulation bone dry from the inside. although the sil-nylon outer layer/less than deal with has held the rain and wind out.
