I see you like VBL clothing around a bag liner…is there a certain set up you advocate Which may work very best presented my situation?
g. main a pitch and afterwards belaying a climbing husband or wife up for the anchor. for prime aerobic get more info pursuits like jogging, skate skiing, or alpine touring (AT) racing, I uncover it nearly impossible to prevent sweating and thus VBL’s are likely inappropriate On this context.
attending to the concern now, :), it appears that evidently wearing a thin wool foundation layer close to the pores and skin might be more cozy than artificial beside the skin. I say this due to the fact, as soon as you climb out on the VBL\sleepbag, the chilly air is going to strike your base layer and you may be right away chilled but with wool’s inherent insulation Attributes while damp or damp, would reduce this outcome. Also, according to your conclusions, if I'd slept inside a VBL that weekend, I suppose the down bag or bivy inside of would have been dry, appropriate? Thanks on your reaction and time Andrew.
Your knowledge of these fabrics is inaccurate. both equally are categorised as “water resistant-breathable,” which happens to be a smoke-and-mirrors time period for a fabric that supposedly prevents humidity from passing by way of it though also allowing for humidity to pass through it. Huh, what? That’s called marketing. In reality, these fabrics do breathe, albeit not virtually and, say, a base layer shirt or even the lightweight shell fabrics the thing is on most sleeping luggage these days. So if you perspire in the evening, this perspiration will go through the internal cloth, into and ideally with the insulation, and thru the outer fabric, wherever it'll evaporate.
If this kind of mechanism exists, then VBL would preserve h2o and electrolytes, and also physique heat. definitely from what you report, under large workload this putative opinions mechanism is not enough By itself to regulate perspiring adequately. Maybe, however, this type of system could make a big variation all through low effort times such as sleeping.
1st, the fundamentals, without having moving into the science of gradients and relative humidity n’ these: When current in the perpetually frozen ecosystem, a single should remain diligent on a handful of matters.
fantastic point concerning the sublimination. nevertheless, it’s not significant adequate to reliably and promptly dry points out. you happen to be greater off avoiding things from acquiring damp.
After the good results of a VBL in my sleeping bag last calendar year, and plastic baggage on my feet I’m taking the RBH VBL jacket and socks out to play this winter :). My only concern is damp toes 24 hrs per day for the lengthier legs (1-3 months).
This should reduce humidity from passing thru the fabric into your down. It in theory would also let for almost any humidity that did get to the down to move thru the material when I hung it nearly air and dry out.”
I believe that VBL’s is usually a essential and pivotal part of winter clothes and equipment systems—and, to your lesser degree, shoulder-year programs. regretably, There may be not Considerably details accessible on VBL’s—a web lookup returns details that is usually outdated, incoherent rambling, or mistaken.
Andrew Skurka on December 28, 2022 at five:36 pm I often purchase the Altitude liner, because it’s not much costlier or heavier than one other versions, because it provides you with the choice to go lessen when compared to the Other people, and since there’s an uncomplicated solution when you don’t want this type of heat liner (you take from the gloves and clip them into a carabiner with your shoulder strap).
The just one downfall with VBL garments is I need to get a complete VBL suit, which happens to be heavier and more complex than the usual bag liner. In the long run, my sleeping bag may be compromised if I'm not wholly included with VBL’s. A complete go well with would include socks, trousers, jacket, gloves, plus a hat or balaclava.
The rain-pris operate very like a vapor barrier trapping the heat versus your body rather than letting it evaporate to the skin and chill […]
18 beneath Fahrenheit or Centigrade? Either way, wow, That may be a cold bicycle journey! I’m not Andrew, but should you don’t head my remark: thanks for earning my issue, 1 which I have typically made when speaking about VBs with those who don’t like the principle in the slightest degree! And that time being: Regardless how breathable, with sufficient action I am going to sweat, even though it is extremely cold. particularly when carrying a pack. And that does not even rely the tiny amounts of sweat which i don’t even see, plus the insensible perspiration, i.
