I’m wondering things like a down puffy which has a DCF or silnylon inside, and so forth. looks as if This may do the job perfectly as long as the outer material was air permeable to permit lofting and compression.
Andrej Badin on March ten, 2024 at 1:00 am Dear Andrew, thanks for a good report and also a lively discussion! Could you Most likely elaborate a little bit a lot more on using VBL’s in relation to Over-all hygiene whilst staying on course for weeks and for a longer period devoid of a chance to wash/dry dresses within a heated shelter/developing? would you wash your sweat soaked baselayer utilizing soap, wring it, put it again on and go on hiking, drying the garment using your system heat?
This assumes that your perspiration doesn’t strike the dew position as it's passing throughout the bag, wherein case it'll condense on to the insulation or even the shell cloth. Fabrics that breathe as a result, even at a limited amount, never purpose as vapor barrier liners. A VBL material performs far more such as 30D silnylon that you are intending to use for your floor — it's watertight but not breathable.
(Without a VBL, perspiration would shift absent from your body and through outer levels (if applicable), and then hopefully evaporate in the ambiance.) This entrapment of moisture has a few Added benefits:
in case you experienced a VBL bag liner or clothes, your website sleeping bag would not have grown to be moist from perspiration, which might have improved your circumstance. But the down continue to would've absorbed ambient humidity, triggering loss of warmth.
Vapor barrier liners generally is a pivotal and critical addition to wintertime and shoulder-time clothing and tools methods, specifically for those people who are outside for extended periods of time in frigid circumstances. VBL’s avoid loft-loss, persuade improved thermoregulation, and minimize evaporative warmth loss.
The artificial quilt option just isn't a sustainable Answer to humidity Establish-up in Winter season conditions. It works for a couple of days, but it'll are unsuccessful very long-term.
once the results of the VBL in my sleeping bag final year, and plastic bags on my toes I’m taking the RBH VBL jacket and socks out to play this Winter season :). My only problem is moist feet 24 hrs daily to the lengthier legs (1-3 weeks).
There was also mention by Kate of sewing 2 House blankets collectively for making a sleeping bag VB liner. Andrew felt it wouldn't be a good idea resulting from insufficient sturdiness and because it will result in sweat and lure all humidity due to not becoming breathable. OK, I see that It could be fragile.
I have an ultralight REI 0 degree 800 fill down bag which includes served me incredibly perfectly through the years. Ive gone Winter season tenting with it repeatedly within the Adirondack mountains of NY but nothing at all for a longer time than a few days.
Once i get way too sizzling, I sweat, VB or no VB. (obviously, VBs warm me up, so I would sweat at a reduced ambient temp). But Once i sit round the household at about 70F, from the air conditioned dwelling- given that I use no other levels- I usually do not get moist when donning my SWL VB shirt with Fuzzy Stuff liming. Same if I sit exterior with a coolish day: providing I am not carrying a lot of- or perhaps every other- levels, I never accumulate moisture In the VB.
it truly is attention-grabbing to study the critics from the vapor barrier method who have never actually knowledgeable the amazing general performance at sub zero temperatures. In all it provides the advantage of preserving the insulating capacity of down by keeping it dry, and decreasing the amount of insulation required overall by blocking the cooling influence of insensible perspiration. employing a light layer of synthetic extensive underwear, then a lightweight rain suit, accompanied by heavy fleece my summertime body weight down terrible delivered a lot more than sufficient insulation to help keep toasty warm at zero degrees. An impressive overall performance. For the individuals with chilly extremities, ft and palms, even something so simple as a bread bag more than a liner sock after which a heavier insulating sock will make your toes really feel like they are being warmed by a Wooden stove.
I don’t believe regular shell levels would have ‘breathed’ quickly more than enough to allow the moisture to dry before it froze to the lining.
aquiring a merino wool foundation layer might have aided some in maintaining you heat, but I do think the conditions degraded your technique so seriously that you probably still would have been quite cold and would have necessary to head into city the subsequent working day.
