Just as VB necessitates very careful thermal administration, it’s also fairly doable to deal with the amount of moisture buildup inside a non-VB sleeping system by preventing overheating. In that regard, your level about donning further insulation levels less than your sleeping bag is effectively taken: that additional layer generates yet another temperature gradient in between you as well as insulation in the bag, earning condensation In the bag (as well as with your layers) more probably. I’ve observed that, for the most part, trusting the bag to maintain you heat all the way down to its “convenience score” with nominal or no levels, as overwhelming as it might feel whenever you to start with get into a frigid tent, pays off in the end, and will often bring about a comfortable evening’s slumber while not having to deal with a damp VB liner, and with little if any condensation Within the bag.
throughout the day, aside from my base layers, which can turn out to be a bit moist with perspiration. If I were to depend exclusively with a VBL bag liner, perspiration would enter and come to be trapped in my insulated jacket and pants when I dress in them all through rest stops or in camp.
I originally imagined which the moist accommodate would continue to keep you warm about the surface too. But many of us found out that on wintery times with wind and rain or snow which the soaked match did minor to shield us and we set big significant jackets over the damp fit. I do think perhaps it was the drinking water evaporating from the wet fit that brought on the fast cooling.
I’m wanting to figure out any adverse consequences long-time period Wintertime hiking might need (frozen boots namely), but given That which you stated it seems far more like a concern of ease and comfort instead of requirement.
one. RealFeel Temperature®. I never essentially use AccuWeather’s patented index, but I feel The thought is useful—It's really a measure of every one of the environmental elements that affect how heat or cold I am. This would come with ambient air temperature, wind, Sunlight publicity, precipitation, humidity, and ground include. I realize that I can begin to have on VBL gloves in temperatures underneath forty levels F, a jacket and socks beneath 20, and trousers down below ten.
according to daylight temperatures and photo voltaic power, you might or might not have the ability to dry the insulation. I wouldn’t rely on it on a visit in MN in January, but AK in April, that is extra very likely.
This is all really intriguing while, I realize that I will attempt to discover effectively about VBL so I am able to place it to check as quickly as possible….
g. Pertex protect+, a Gore-Tex, et al. This then to circumvent back again-travel/absorption on the amassed liquid on the bag’s internal facial area back in to the garments’s insulation from whence it to start with came. undoubtedly the humidity in the milieu among the puffy’s breathable nevertheless ‘water-proof’ shell and also the certainly water resistant inner shell of your sleeping bag wouldn't develop into so good in the course of an evening’s slumber that your body’s outward bound perspiration could well be stopped from penetrating outwards in the puffy’s shell, i.e. the puffy’s shell stops respiratory…or?
many thanks for all the great details. You’ve performed an exquisite career at describing one thing I, like a seasoned backpacker, just read about for The 1st time in preparation for my to start with mountaineering journey. Like Other individuals, I too have winter camped and experienced dampness on my down sleeping bag and questioned why it absolutely was soaked in the morning. For my approaching trip, I will probably be sleeping in a two particular person, 4 year tent (very well ventilated, but heavy Even so).
Additionally, it looks that almost all folks- totally educated in the advantages of breathable equipment- only do not comprehend the notion or science of VBs applied at or incredibly close to the warm pores and skin degree. It seems to me that science presents us/them 2 decisions: Our physique sweat(liquid) can evaporate to vapor- causing evaporative cooling- off of our skin and vacation into our insulation, or sweat could be wicked into our insulation in liquid variety as it would be by using a sponge. Which retains our pores and skin sensation pleasantly dry! Our human body vapor(not liquid but) basically travels into our insulation, and we/they hope the vapor(fail to remember sweat, already liquid) will keep on likely for an inch or three or 4 and NOT come across the dew issue In the shell and condense back again into liquid. ideally, that vapor will just carry on likely past that breathable shell into your atmosphere which could by now be a hundred% humidity(vapor travels from significant humidity to reduced, ideal? Not from reduced(close to the pores and skin to greater- outside the shell perhaps now one hundred%). That is the intention, and from time to time it really works completely, Though they are still working with evaporative cooling in the pores and skin stage. If it doesn’t operate flawlessly every one of the time, then evening immediately after night, some vapor hits the dew issue and condenses into liquid, or their sweat will get absorbed into their down, and loft decreases day after day, if no Solar is useful for drying. from time to time all of this freezes into ice Within the down!
you start your day with a thin layer of polypro or wool between the skin and your VBL. through your working day of exertion, you vent the ideal it is possible to to keep your underneath layer at ease and if you get to your camp, carry on venting your VBL As you Cook dinner VAPORBA and setup camp. if you go to mattress, In the event your poly professionals are still soaked plenty of that you just don’t choose to snooze in them, transform right into a dry pair and position your damp kinds in the plastic bag along with a reusable desiccant, and location it in your sleeping bag. after you wake up, you'll have heat dry longies to change into.
Trouter on February three, 2016 at ten:53 pm Andrew, many thanks for the in-depth explanation from the VBL approach. I Winter season camp in northern Minnesota, And so the temps certainly warrant loads of imagined on gear, outfits, and procedures of retaining heat. I’m thinking about a VBL liner from Rab (hyperlink below). My query is with regards to the morning When you’ve slept that has a VBL bag or VBL outfits.
Not A great deal luck at Individuals temps and humidity. I was soaked. Baselayer, second wool layer, puffy vest, and after that a breathable jacket. I feel like I might be superior off that contains the sweat. possibly a light baselayer, followed by a complete vapor barrier for upper and decreased system. I’d be greater of containing the sweat instead of staying soaked and freezing. I had a fresh new baselayer on the 40 mile checkpoint, but didn’t dare continue. Do they generate a vapor barrier for your torso and legs that might do the job for me? Do you have any tips not merely on where to secure a set, and also if you're thinking that it’s a good suggestion. many thanks a great deal beforehand for virtually any assist you could give.
Our bodies are intended to get rid of a certain degree of dampness, regardless if sleeping rather than overheating. Hence, in my view, the optimum sleeping procedure is one that permits for these types of “program” humidity reduction without having compromising its insulating properties.
