There may be some video clips and reviews on youtube of this extremely-light bivvy bag, and it just could possibly be Whatever you are looking for to put into pants to produce a vapor barrier, as it seems just stretchy enough that it'd perform…

I relied on incredibly hot water bottles in my sleeping bag, worked great. During the day I wore Paramo clothing as being a important ingredient inside a layering system, I'd no issues with system dampness mainly because it breaths so well .

I anticipate encountering the damp/humid disorders regular towards the southern appalachians and definitely I’ll be struggling with winter weather conditions. could it be unavoidable that my bag will become compromised without the use of VBL’s or do you think I’ll be ok with preventive Sunshine drying? Thanks,

getting employed VBLs in sleeping bags on Possibly a half-dozen one-evening outings, I received the effect which they additional recognizable warmth in temperature in between 15F and zero, but presented a virtually imperceptible edge (if any) on evenings that were basically neat.

SoI applied a elaborate patigucci polypro with which I bought much too warm (study sweat). On a whim I attempted a mesh shirt produced by Wiggy’s and had remarkable results. The mesh aids set up a layer of lifeless air space concerning myself along with the VBL with none conductive warmth decline. It worked so very well I compensated just about thrice just as much for the Brynje shirt from Norway. all the more fantastic. I feel the mesh is definitely the missing factor in VBL programs.

to start with, the basics, without the need of entering into the science of gradients and relative humidity n’ this sort of: When existing within a perpetually frozen environment, one particular need to stay diligent on a handful of factors.

five mm shirt and trousers as being a base layer for my occasional alpine skiing outing. I just want to remain heat but not bulky and am accustomed to the clammy feeling of a wetsuit. for your personal more demanding wants I am able to see how a shirt and pants mix would lead to perspiration to escape in between trousers and shirt instead of be a whole barrier. The shirt also needs to have a zipper to typical heat given that wetsuits are certainly productive with warmth and humidity retention.

Great write-up and fantastic data! Thanks much for acquiring it on the market. I are already pushing to the winter camping A lot more and have found extraordinary profit to employing a VBL.

The 1 downfall with VBL garments is I need to have a whole VBL suit, that's heavier and even more complicated than a bag liner. In the long run, my sleeping bag could possibly be compromised if I'm not fully protected with VBL’s.

through my Ultralight in the Nation’s Icebox hike, I had been joined for an evening by Backpacking gentle staffer Sam Haraldson, whose clothing and equipment technique lacked VBL. soon after hiking for several hrs, Sam removed his watertight-breathable jacket to discover a layer of frost inside of it, on account of his perspiration turning from vapor into drinking water as it attained the dew point, which was inside his outfits technique.
