very same After i slumber exterior in winter in my hammock, within quilts, sporting my VB shirt: though I sense Considerably warmer than devoid of it, Unless of course I incorporate adequate layers to truly above warmth, I am not aware about sweat. Usually, Along with the SWL VBs as well as their lining, I'm not even aware about that renowned VB clammy feeling.
as a result, while it had been here inappropriate to your early reference to cite that “that the substantial humidity envelope developed by VB ‘…discouraging as well as halting the production of insensible sweat,’” it would have been appropriate for that reference to condition that at a adequately substantial humidity, however the creation of insensible sweat proceeds, its evaporation is halted, and As long as physique temperature carries on to travel the creation of this sort of sweat, it can proceed to accumulate in a very pool.
This assumes that the perspiration doesn’t hit the dew level as it really is passing in the bag, by which circumstance it will eventually condense on to the insulation or the shell material. Fabrics that breathe therefore, even in a limited level, will not functionality as vapor barrier liners. A VBL fabric performs far more just like the 30D silnylon you will be intending to use for any flooring — it can be watertight although not breathable.
How will you regulate the moisture from a breath when you're sleeping? Sorry for a bit off subject matter but I soaked my sleeping bag previous night in -20C temperature (feet and head spot) and came below trying to find moisture management abilities!
see the accent carabiner on my shoulder strap, which is among the ways I make speedy and efficient adjustments to my layering system.
It’s Maybe finding alternatively esoteric listed here but I’m sport to become corrected and educated if you can spare your time and efforts and wisdom to shape my comprehension of these mysteries.
That is all genuinely fascinating even though, I understand that I will attempt to find out appropriately about VBL so I am able to place it to test at the earliest opportunity….
You will need to have study some incorrect information regarding synthetic vs . down insulation with respect to dew details. The mechanics are exactly the same for both varieties of insulations:
confident it won’t penetrate my fleece or down jacket, but what occurs to it then? I get that VBL is very best fitted to very cold environemnts and situation, but go ahead and take Ski case in point. This was incredibly well described, I have experienced it all my lifetime for a Skier, once the Sunshine drops down driving the mountains, the temperatures tumble dramatically, and you obtain seriously chilly in a short time as your clothing are all wet from the working day’s intense skiing…. but when i were carrying a VBL, while skiing, I’m fairly confident it would have prompted me to sweat a lot too, if no more, then in which would all this sweat go? Or is the idea that generally we assume which i would have eliminated more than enough of my gear during the day that I wouldn’t have sweated?
But, OTOH, given that I started out using the SWL with fuzzy stuff, I don’t try to remember at any time sensation disagreeably moist, sticky and clammy, besides on those number of moments After i Permit myself over heat and began outright sweating. And which includes undoubtedly happened, although even then the humidity did not go into my insulation And that i didn’t put up with evaporative cooling. But, I agree There exists a superior bit about the complete topic that's subjective. It will be quick more than enough To place it towards the scientific exam as far as heat and loft retention, but I haven't seen that. aside from my own individual experiments, with N=one. So, that is rather modest numbers to get a scientific research!
This technique would not be immune from moisture issues but would be way more immune to them. This is a reasonably standard go-to set up for me when hiking within the cold and wet situations you may have explained.
The MSR Dragontail is an excessive amount. A double-wall tent created for three-time ailments could well be a more sensible choice: a few kilos lighter, as well as the internal tent will safeguard you from condensation that collects on The within with the rain fly.
g. dry the bag in mid-day sunshine. The degradation could well be far more significant if it had been colder or wetter, or in case you’d been out for for a longer time.
What would you advise for general warmth sleeping versus the particular summit drive where There's extra exertion, it’s even colder/windier and it’s Considerably more difficult to get rid of levels effortlessly. aquiring a hard time determining what my procedure needs to be.
