I just did my first “Deep Winter season” tenting vacation this past March plus the temps have been 19F throughout the day and bottomed out at -17F during the night. I used to be considering striving to include your idea of a VBL that can help increase my gear and decrease my Total pack bodyweight. nonetheless, VBL clothing is usually pretty pricey And that i’m not that talented when it comes to generating my very own clothing.
during the day, except for my foundation layers, which can grow to be a bit moist with perspiration. If I were to count completely over a VBL bag liner, perspiration would enter and turn out to be trapped in my insulated jacket and pants although I don them throughout rest stops or in camp.
The author mentioned his sleeping bag gained about thirty pounds of ice all from human body humidity. every time he produced camp it took more time and extended to warmth up the bag so he could fall asleep.
Personally, I desire luggage that use very breathable nylon or polyester shell fabrics. They're lighter and cheaper than WP/B fabrics, and MUCH more breathable.
I applied to incorporate these in my juggling costumes, to keep The material from pulling After i raised my arms in excess of my head! Got The theory from the costuming ebook, and it’s always irritated me that athletic outfits basically lacks this characteristic.
Steve Dickens on April 26, 2021 at nine:eleven am Andrew, many thanks for the in depth post. I’ve under no circumstances fully made the change to VBL (other than a bag liner for extreme cold). nonetheless, since I’m obtaining older (65) I need all the assistance I might get. I’ve been thinking of a VBL shirt under my foundation layer, but here’s what I don’t get. You point out which the VBL system partly is effective involving it'll cue the user to shed layers and ventilate faster, as opposed to waiting around get more info for a long time to do so. Possibly my pores and skin is much more sensitive than most, but I discover sweat instantly and lose quickly (I'm hypervigilant about that and would by no means make it possible for myself to acquire damp — to me that challenges hypothermia and death).
must I keep on with the semi-breathable Gortex shell I have, or really should I receive a shell that also passes no water vapor? Would shell layers improve if it absolutely was hotter plus much more humid, say just higher than freezing throughout the day with sleet?
till Andrew responds, here is my opinion. The VB applied by itself will most likely be hotter than a skinny foundation layer, and much hotter if worn beneath that base layer.
for your personal fingers plastic disposable gloves will work, or alternatively Test gloves in the pharmacy will do the trick. there is absolutely no should get expensive equipment to outfit your self. in actual fact if you will discover another person useful by using a sewing machine a few yards with the lightest silnylon will serve to fabricate a rudimentary pair of pants and tunic top. In the final analysis that setup will weigh considerably lower than a Wintertime body weight down bag and all of the accrued dampness of days out while in the chilly.
When at full output in temps of ten beneath, I guess you can get absent with just a few levels: a really gentle foundation, a VBL layer, and after that Possibly a fleece or really light-weight insulation.
a single exception is my feet. They are often so heat I come to feel like they are perspiring. As opposed to lots of who complain of chilly toes although hanging in the hammock. I Typically ignore it and just sleep with overheating ft. But After i consider from the VB socks another morning, although my toes do without a doubt sense toasty warm to the contact, there is normally no perceptible liquid.
I was thinking of using celebration or HyVent substance on both sides. This could protect against moisture from passing thru the fabric in the down. It in idea would also allow for for just about any moisture that did reach the down to go thru the material After i hung it approximately air and dry out.
Andrew Skurka on November 18, 2012 at five:51 pm I figured that mesh base levels would operate very well beneath VBL’s, so it is nice to understand that they in fact do. 1 difficulty to be expecting, having said that: mesh is just not worthy as being a standalone foundation layer, considering the fact that it doesn't offer you defense in opposition to UV or wind.
A VBL is usually a non-breathable material that does not allow the transmission of humidity via it. They are generally fabricated from fabrics like silicone-impregnated nylon, polyurethane-coated nylon, or Mylar; and there are at least two multi-layer proprietary fabrics way too. inside of a pinch a VBL could possibly be constructed from a plastic trash bag or perhaps a foil balloon—I have accomplished each; in essence, any product that doesn't “breathe” will get the job done.
