But my query is: if insensible perspiration, assuming I vent or take away levels as needed to stay clear of above heating and outright sweat, continues unabated and irrespective of human body temp of humidity with the skin, why don’t I wake inside of a pool of liquid just after 8 hrs inside of a VB? Or why don’t I get soaked in sweat even though sitting down around at home temp, or a tad below, or outside the house from the 60s?

e. the little volume of dampness Your entire body places out 24/7 even though we aren't about heating, and which we do not even notice. But still causes it to be’s way bit by bit but definitely into our insulation. the place we hope it keeps on undergoing our breathable levels into the air, but the place it sometimes hits a chilly location and condenses into liquid.

Otherwise for becoming invited inside of one-two instances each week by generous locals and possessing the opportunity to dry my issues, I definitely might have shivered by way of far more evenings than I truly did. the entire compromising of a few of my most important products was unstoppable Together with the technique which i had.

would it not actually, considering that the dew stage might be someplace within the sleeping bag’s insulation? I might surmise the vapor would ‘want’ to travel right in the clothing program and outward along the temperature and humidity gradients to some (dew)place identified deep in the sleeping bag. sadly for Mr. Vapor however, the outward sure drinking water vapor would speed correct in to the proverbial brick wall when it achieved the sleeping bag’s water-proof interior shell. Potentially then a VBL-match wouldn't be desired whatsoever–just an outer shell on the puffy that was breathable still markedly ‘water-resistant’, e.

Steve Dickens on April 26, 2021 at 9:11 am Andrew, Thanks for your in depth write-up. I’ve under no circumstances fully designed the swap to VBL (aside from a bag liner for Severe cold). nevertheless, given that I’m finding more mature (65) I would like all the assistance I can get. I’ve been thinking of a VBL shirt under my base layer, but in this article’s what I don’t get. You condition the VBL program partially works between it's going to cue the person to lose layers and ventilate sooner, as opposed to ready for some time to take action. Maybe my skin is much more sensitive than most, but I see sweat quickly and get rid of promptly (I'm hypervigilant about that and would under no circumstances allow for myself to have moist — to me that dangers hypothermia and death).

There was some loft shed way too. I was considerably involved that compressing the bag to move to new spot might clump the down in upcoming extended Wintertime visits.

While I'd VBL, I took advantage of a comparatively warm and sunny working day to dry two sleeping luggage plus a bivy sack, which experienced turn out to be somewhat moist as a result of snow-covered ground and frozen moisture from respiratory.

this could lead to down and artificial insulations to eventually collapse. and it'll cause undesired evaporative heat reduction with other fibers like polyester, nylon, and wool.

And it’ll surely be above freezing during the day, in which you'll “reset” dry” your sleeping bag just about every several times if you do observe that it's accumulating some humidity.

Bill Kline on November 8, 2017 at 11:24 am perfectly There are plenty of different ways to have it accomplished. I have deemed the substantial $ strategy like RBH, predominantly since it seems ok to have on some location in addition to the woods, and I should still try this some day. But from the signify time, I don’t sense I've ever experienced nearly anything far more handy, with regard to $ or pounds, than my Stephenson’s Warmlight(sp?) VB shirt(SWL). It Expense very little, weighs 8 oz in XL like Fuzzy things liner, which implies I don’t really need to use a thin lengthy john major less than it for read more ease and comfort. If I have a skinny LJ top rated with me anyway(most likely do), which can be yet one more layer to go around the VB shirt for added insulation, assuming it is actually big enough. Or additional down below to my hammock insulation. And that i obtain it really comfortable and low odor. What it lacks is vent selections like pit zips so climbing can definitely need a large amount of VB skill needless to say. But for low Vitality exercise, or sleeping/sitting down about camp, it has proved enormously effective. Only detail is I don’t have trousers, they need to be custom made manufactured or you buy the material and DIY. I do have their socks and gloves, they usually work just great also. I credit rating these things with the ease of my all time own lower in the hammock of +6F . employing nothing at all in excess of the much maligned Hennessy Hammock Super Shelter(HHSS). When going down below twenty using this type of arrange, I've usually augmented by incorporating/putting the extra 3 oz HH torso/kidney pads, in addition regardless of what I was not sleeping in- down vests and/or fleece jackets, what ever I had- down In the beneath cover underneath the normal HHSS open up cell foam(OCF) pad, and performed good at 14F in addition wind chill.

I was thinking of employing party or HyVent materials on both sides. This should prevent moisture from passing thru the fabric into your down. It in theory would also permit for any dampness that did get to the down to pass thru the material After i hung it approximately air and dry out.

It needs to be quite a bit below freezing to justify VBL’s. If it’s a 20-deg low, it’s probably continue to earlier mentioned freezing with your shelter.

I’ve also listened to that VBL socks can assist to stop boots having moist as a result of perspiration and will be Specifically useful with leather-based boots, which keep dampness more time than synthetic. Is that this genuine?
