But my query is: if insensible perspiration, assuming I vent or take out levels as necessary to keep away from about heating and outright sweat, continues unabated and regardless of body temp of humidity for the skin, why don’t I wake within a pool of liquid immediately after 8 hrs in a VB? Or why don’t I get soaked in sweat even though sitting about at room temp, or a little below, or outside the house during the 60s?
And do you sometimes use the Warmlite with a layer beneath, or straight beside the pores and skin? and when you’re interested by the situations for that race I talked about, the place I was frozen and soaked, lookup Ben Doom’s Blog. He gained the one hundred sixty mile race. You can read his account of exactly what a wrestle it absolutely was Along with the cold and humidity. sixty three% of participants quit.
I’m not concerned about The dearth of “waterproofness” — my shelter serves this functionality incredibly perfectly, and WP/B fabrics aren’t that waterproof anyway.
Your knowledge of these fabrics is inaccurate. both of those are categorized as “water-proof-breathable,” that's a read more smoke-and-mirrors term for a material that supposedly stops moisture from passing by it when also enabling moisture to pass through it. Huh, what? That’s known as promoting. In fact, these fabrics do breathe, albeit not practically as well as, say, a base layer shirt or the light-weight shell fabrics the thing is on most sleeping bags currently. So any time you perspire during the night time, this perspiration will go through the inner material, into and with any luck , throughout the insulation, and thru the outer cloth, where it is going to evaporate.
Also, neoprene dries little by little, and it’ll dry even more bit by bit at VBL-worthy temperatures. So any humidity that receives into the material would probably stay in it.
a short while ago, I procured a sleeping bag VBL produced by Western Mountaineering and find it irresistible! I have tested it out in a 32 diploma WM Summerlite bag in -9 diploma weather… Here's the connection to my films in the event you treatment to take a look.
must I stick with the semi-breathable Gortex shell I've, or need to I get a shell that also passes no water vapor? Would shell levels alter if it was warmer and even more humid, say just above freezing during the day with sleet?
That said, if/when I have more money, I feel I’ll Have a look a VBLs. Seems like a good system. Sleeping with down has some compromises, and it feels like the VBLs remedy these.
In this type of circumstance, dampness produced by the human body wouldn't enter the insulation (each morning, the amassed inner moisture may be wiped dry by a lightweight towel to then be frozen accompanied by a defrosting-by-shaking). Moisture from any resource outside of the bag’s external shell could not enter insulation.
2. Even though you deal with your perspiration intently, you will even now sweat, and it will still obtain In the VBL’s. to stay away from extreme assortment, you must air out your VBL’s once in a while. As an example, if I recognize that my palms are overheating in my VBL gloves, I take out the gloves and clip them onto my shoulder strap, and ski as an alternative with just my liner gloves, which can have gathered a small amount of dampness. But within just a few minutes, this moisture has evaporated and I am able to put my arms back again into my gloves.
Layering. VBL’s are generally worn straight in opposition to the pores and skin or having a foundation layer among the VBL as well as the pores and skin. Individually, I like the latter technique, which I believe has a few essential Positive aspects. to start with, the base layer generates a small buffer that minimizes pain (i.e. “clamminess”) but without having minimizing sensitivity to perspiration, which I would like as a way to make informed thermoregulation choices. Second, by donning a foundation layer I defend my skin from direct contact with the frigid air, which might come about or else if I required to ventilate my “next to skin” garment by unzipping it.
But I am not at all. Which makes me Consider providing I don’t about heat and induce acute sweat manufacturing, my vapor or humidity output(from pores and skin) is going to attain a particular place and afterwards end or gradual way down.
Not Considerably luck at Those people temps and humidity. I used to be soaked. Baselayer, 2nd wool layer, puffy vest, and then a breathable jacket. I truly feel like I would be greater off that contains the sweat. probably a light-weight baselayer, accompanied by a full vapor barrier for higher and reduce system. I’d be much better of made up of the sweat as opposed to currently being soaked and freezing. I had a clean baselayer on the 40 mile checkpoint, but didn’t dare carry on. Do they generate a vapor barrier for that torso and legs that might get the job done for me? Do you may have any recommendations not only on the place to secure a established, but in addition if you think it’s a good idea. many thanks much upfront for almost any enable you can give.
naturally (1) it isn’t the ambient nevertheless the intra-VBL temperature that is certainly applicable to this conversation and (2) all sweating is greatest regulated via the behavioral option to lose/modify layers as required, so the issue should frequently be effortlessly avoidable.
