There's some movies and reviews on youtube of the extremely-light bivvy bag, and it just may very well be That which you are trying to find to put into pants to make a vapor barrier, because it appears to be like just stretchy plenty of that it'd do the job…
Chris Xavier on April twenty, 2016 at one:sixteen am Hey Andrew, I am aware I’m late into the celebration but this is really intriguing stuff. I have some questions. My software for this this sort of procedure might be multi day substantial output alpine climbing in cold and snowy situations. Anyway, if I had been to include a full VBL go well with in my set up, would that imply that i could forget the use of a fleece and as an alternative opt for a lightweight down jacket as my active insulation layer? (with An additional higher fill jacket for your prevent layer). I figure that since i don’t actually need the breathability of a fleece within a situation in which I’m donning a VPL, i could possibly get much more heat for the weight by heading having a down jacket.
prevent-and-go activities like climbing and backcountry alpine skiing are complicated for VBL use for the reason that your warmth output is a lot more erratic.
Individually, I favor bags that use hugely breathable nylon or polyester shell fabrics. These are lighter and cheaper than WP/B fabrics, and MUCH more breathable.
I get outside of my bag in the morning with all my warm apparel on, in place of having to put on cold clothing that sat outdoors my bag all evening.
Andrew Skurka on March 21, 2014 at ten:07 pm not less than one particular side from the bag would want being breathable, or else the bag would resist lofting following becoming compressed, or compressing immediately after being lofted (since a non-breathable material isn't going to enable air to go through it, so essentially air move will be restricted to the seams).
I am aware which one particular I constantly selected if there is any possibility of not currently being heat ample for a number of evenings Using the insulation I have with me. Or, if I am just needing to cut back insulation bulk and body weight and make sure I don’t unfastened loft night time just after night.
g. Pertex Shield+, a Gore-Tex, et al. This then to prevent back-travel/absorption of the amassed liquid with the bag’s inner confront again into the apparel’s insulation from whence it very first came. definitely the humidity from the milieu amongst the puffy’s breathable but ‘water resistant’ shell and the genuinely water-proof interior shell in the sleeping bag would not turn out to be so fantastic click here during an evening’s rest that the body’s outward sure perspiration could be stopped from penetrating outwards through the puffy’s shell, i.e. the puffy’s shell stops breathing…or?
There seems to be a good deal of confusion and mystery about VBL’s, and thru this short article I hope which i managed to further improve standard understanding and inspire a lot more common use by describing the things they are, how they get the job done, and when and how to make use of them.
Andrew’s response gave a number of main reasons why This is able to not operate, like at the very least 1 layer would want being breathable for packing up, and: “This breathable facet couldn't be on The within, adjacent on the sleeper, due to the fact dampness would accumulate Within the bag versus the non-breathable layer. “.
When I get far too sizzling, I sweat, VB or no VB. (certainly, VBs warm me up, so I would sweat at a lessen ambient temp). But After i sit round the house at about 70F, within the air conditioned residence- so long as I use no other levels- I never get moist when carrying my SWL VB shirt with Fuzzy things liming. identical if I sit outdoors with a coolish working day: assuming that I'm not wearing a lot of- or perhaps almost every other- levels, I will not accumulate moisture Within the VB.
On an uphill snowshoe, I am all the way down to my thin base layer shirt right away (normally initially 1/two mile); I do notice that my close friends are inclined to maintain quite a few garments on for much, much for a longer time. And that i’m however heat (of course according to the temp). I fear the VBL shirt is going to be even warmer than my base layer and actually trigger me to sweat more. clinical pals have explained to me that it's not exact that the human body stops sweating when it detects dampness near the pores and skin – don’t know when they’re suitable. Any views re. my problem helpful.
1st, many thanks for your time and effort investigating, experimenting, and publishing your conclusions. I'm new to hiking, two several years, and area climbing the AT. I seem to be gravitating to off-season climbing staying away from the crowds. I hiked the main weekend in March at close to 1500′ in sleet and slept in the thirty diploma down bag, REI Bivy, with my artificial base layer and wakened three:00 in the morning because I had been moist and very cold. The bag was damp on the surface, my foundation layer was damp on my skin and inside the bivy was slippery moist. The good news is, I used to be in close proximity to a town and was able to make it to the laundromat and dry almost everything that morning. Last yr, I hiked Vermont for a week in late August less than soaked disorders, ft ended up wet The entire time but was putting on wool socks and I never ever felt awkward.
Andrew Skurka on March 18, 2014 at five:24 pm For such a brief work and for such a comparatively high aerobic exercise, I don’t think that VBL levels sound right. I Luckily don’t should commute to operate, but I do operate through the entire Winter season, and for definitely chilly conditions like that I realize that breathable but warm levels — like merino or fleece sweaters, and expedition-bodyweight tights — work very best, maybe coupled with a wind-breaking layer if essential (possibly inside your situation, not always in mine).
