I’m imagining things such as a down puffy using a DCF or silnylon interior, etc. looks like This might get the job done nicely as read more long as the outer material was air permeable to allow lofting and compression.
nearly all of my fifty percent-dozen or so nights with VBL were with the trash-bag/duct tape range, Despite the fact that I did sooner or later purchase a created liner.
I feel I’ve observed a ecu-dependent cottage business company of sleeping bags to assemble the bag after I’ve preferred components and settled on a rough style.
I have a hunch that these fits would function pretty well as VBLs, but considering that they’re meant to be worn over apparel they’re really baggy. would you think that would make any complications?
for those who experienced a VBL bag liner or outfits, your sleeping bag wouldn't are getting to be soaked from perspiration, which would have improved your problem. even so the down even now might have absorbed ambient humidity, leading to loss of warmth.
Theres a handful of 0.5mm neoprene parts in existence (largely NRS hydroskins) but regrettably all the tops have polyster vents below the armpits!
A cautious knowing of ASTM E1643 is needed When selecting and setting up a good underneath-slab vapor proofing process. Specifiers and installers alike can get pleasure from the issues specific Within this conventional practice.
following the results of a VBL in my sleeping bag past year, and plastic luggage on my feet I’m getting the RBH VBL jacket and socks out to Enjoy this Wintertime :). My only worry is damp ft 24 hrs on a daily basis for the more time legs (1-three weeks).
There is apparently a good deal of confusion and thriller about VBL’s, and thru this text I hope which i managed to boost common comprehending and inspire much more widespread use by explaining what they are, how they get the job done, and when and the way to use them.
Miller on October 20, 2021 at 9:forty nine am fantastic article! My own expertise with VB is essentially limited to long-sleeved shirt made out of silnylon with What exactly are effectively gussets on the neck and sleeves. These fold about and cosy up with some more velcro. If likely pretty difficult I place it on the bottom layer, if average or stationary I dress in it in excess of a foundation layer. I experimented with knee-size pants, but legs crank out a lot far more warmth in movement and I could hardly ever control sweat output – soaked underpants are not definitely worth the profit.
following a couple of years I transformed into VB dresses and haven’t changed the thought since, just extra a few tweaks; hotter lighter bag, VB headgear,at times a ‘shaped’ tarp. The combo of VB layer and biv sack keeps the sleeping bag or quilt dry and clean, Even when you bump against a frosty tarp.
many thanks for the wonderful article. I have utilised bread bags on my feet For several years now but each and every so frequently I am plagued having an annoyance which makes me steer from about to a far more significant falootin’ process for my ft. to be a geezer, nearing 70, my hands and toes are sometimes chilly while snowshoeing here in Northern Ontario and Quebec. There is no issue over it, using a vapour barrier is excellent and keeps the toes warm and insulation dry.
in the long run, the all-synthetic system will fall short as well, but Most likely not before I end the trip. Since down is considerably remarkable in its thermal effectiveness, it’s debatable if the all-artificial method will be lighter—such as, I could set with each other a lighter bodyweight all-down method that is definitely unnecessarily warm Firstly but that will still be enough by the end.
Jim Morrison on January 19, 2019 at 12:27 pm I come about to own used a great deal of time in damp suits. Here are several attention-grabbing, I think, facts. most of the people think that there's a layer of water between you and the wetsuit and you simply warm that layer and in some way that keeps you heat. Incorrect. you'll want to limit the h2o involving you and also the suit just as much as is possible if you need to be as heat as is possible.
