Your input, coupled with my initial – and trés naive – speculative suggestion, I’m planning to hire a sleeping bag producer who will personalize a bag to incl. a few of the following style and content technical specs (barring additional developmental solutions, admonitions, tweaks and mods)
which include your sleeping negative, or clothing. it could also lessen warmth loss attributable to evaporative cooling. Assuming the VB may be very close to the skin.
ASTM E1643 gives significant demands, which contractors and architects alike ought to contemplate when specifying and/or installing beneath-slab vapor retarder units.
I’m wanting to figure out any adverse results extensive-time period winter hiking might have (frozen boots specifically), but supplied That which you claimed It appears a lot more like a problem of consolation rather then requirement.
one. RealFeel Temperature®. I tend not to necessarily use AccuWeather’s patented index, but I feel The thought is beneficial—This is a evaluate of every one of the environmental aspects that impact how warm or cold I'm. This would come with ambient air temperature, wind, sun exposure, precipitation, humidity, and floor protect. I discover that I'm able to start to have on VBL gloves in temperatures down below 40 degrees F, a jacket and socks below 20, and pants underneath 10.
a person worry is this will likely lock in excessive vapor. I Usually slumber in just a foundation layer and vent the bag After i get warm. Clothes, and water bottles are stored during the bag to avoid freezing at nighttime. Leaking h2o bottle a potential but thus far has not occurred.
in these layers: the dew position is somewhere between One's body and the surface environment, along with your perspiration will condense from h2o vapor into actual drinking water, So wetting the levels.
two) you have to continuously operate website toward the purpose of becoming heat and dry. You can be moist, providing you’re heat. you are able to be chilly, provided that you’re dry.
This could avert humidity from passing thru the material into the down. It in concept would also allow for for any moisture that did get to the down to go thru the material After i hung it nearly air and dry out.”
is it possible to aid clarify? Are there distinctive scenarios / disorders wherever a single is preferred more than another?
Also, and this is the just one criticism I have of this product or service, the liners use artificial insulation, and over time that should flatten out, relative to down. So by buying the warmest liner, you might be supplying you some buffer when it begins to be much less warm.
Wouldn’t precisely the same drying solutions utilised over a VBL baselayer also be powerful for drying the damp/ frozen non-VBL insulating layer?
Re multi-working day use. Your VBL prime and base ought to have vents (e.g. entrance zip, forearm zip, facet hem zip) to be able to air out effortlessly and quickly; VBL’s with out such vents undoubtedly are a disaster ready to occur. Also, Significantly of the moisture accumulates on The within layer with the VBL, so when it’s chilly more than enough you'll be able to immediately acquire from the VBL, Enable the humidity freeze, and afterwards shake off the frozen moisture.
Jim Morrison on January 19, 2019 at 12:27 pm I happen to possess expended a lot of time in moist fits. Here are some interesting, I think, specifics. most of the people think that there's a layer of water involving you and also the wetsuit and you also heat that layer and by some means that keeps you heat. Wrong. you need to limit the h2o in between you as well as go well with just as much as feasible if you need to be as warm as possible.
