Just as VB necessitates very careful thermal management, it’s also pretty probable to control the quantity of dampness buildup within a non-VB sleeping process by averting overheating. In that regard, your point about donning excess insulation levels below your sleeping bag is nicely taken: that excess layer generates an additional temperature gradient in between you as well as insulation within the bag, creating condensation In the bag (and even within your levels) a lot more likely. I’ve identified that, for the most part, trusting the bag to maintain you heat all the way down to its “ease and comfort ranking” with minimal or no levels, as daunting as it might seem whenever you to start with get into a frigid tent, pays off ultimately, and will often bring about a snug night time’s rest while not having to cope with a damp VB liner, and with little if any condensation In the bag.
Chris Xavier on April twenty, 2016 at one:16 am Hey Andrew, I do know I’m late for the bash but this is admittedly intriguing things. I have several questions. My application for this this sort of technique could well be multi day superior output alpine climbing in cold and snowy circumstances. in any case, if I had been to incorporate a complete VBL fit in my set up, would that necessarily mean that i could forget about the use of a fleece and in its place go with a lightweight down jacket as my Energetic insulation layer? (with A different increased fill jacket for a halt layer). I determine that because i don’t actually need the breathability of the fleece in a very situation where by I’m sporting a VPL, i may get much more warmth for the burden by going with a down jacket.
First, perspiration won't get to outer levels like a windshirt, insulated parka, or sleeping bag. This is certainly massively vital for the reason that in cold disorders your perspiration will frequently keep
I’m wanting to determine out any adverse outcomes very long-term Winter season hiking may need (frozen boots specifically), but provided what you stated it seems far more like a concern of consolation rather then requirement.
I'm investigating elements to generate a hybrid sleeping bag/quilt. The underside of the bag are going to be unlined.
just one concern is this might lock in an excessive amount of vapor. I Generally snooze in only a foundation layer and vent the bag Once i get heat. garments, and drinking water bottles are held while in the bag to circumvent freezing during the night. Leaking drinking water bottle a possible but up to now has not happened.
This really is all seriously interesting nevertheless, I know that I'll try to understand adequately about VBL so I can set it to test as quickly as possible….
Though I had VBL, I took advantage of a relatively warm and sunny day to dry two sleeping bags and also a bivy sack, which had turn into marginally damp resulting from snow-lined floor and frozen moisture from respiration.
I’d get hypothermic Tremendous-quick if I couldn’t keep Functioning really hard. As it truly is, lunch breaks could be dangerous if I’m not cautious to halt out in the wind. I’m considering a VP layer could be just the thing to maintain my insulation dry, however you’re declaring sweating in VP outfits isn’t pleasurable. How will you stay Protected in case you’re sweating difficult in the cold? trying to keep my action to levels right down to in which I don’t sweat isn’t doable.
two. Even when you manage your perspiration carefully, you are going to even now sweat, and it'll continue to accumulate Within the VBL’s. to stay away from abnormal collection, you should air out your VBL’s often. As an illustration, if I detect that my fingers are overheating in my VBL gloves, I eliminate the gloves and clip them onto my shoulder strap, and ski as a substitute with just my liner gloves, which will have gathered a little bit of humidity. But in just a couple of minutes, this moisture has evaporated and I'm able to place my arms back into my gloves.
Andrew, do the thing is yourself probably doing some items in a different way in retrospect on some journeys and in a few predicaments had you bigger utilized hydrophobic down in a snooze process? If this was tackled someplace now I apologize as I might have skipped it as I didn’t study each and every word here.
By the way, as I may have said right before, you are doing keep on to sweat so long as you are alive, Opposite to what a lot of people theorized concerning the vapor barrier approach.
you would probably probable get some humidity inside your daytime outfit but these could probably be dried by way of overall body warmth or during the night time as part of your bag.
I’ve also listened to that VBL socks will help to avoid boots having moist as VAPORBA a consequence of perspiration and may be In particular useful with leather-based boots, which keep dampness for a longer period than synthetic. Is this real?
