Just as VB necessitates thorough thermal administration, it’s also very probable to deal with the level of dampness buildup in a non-VB sleeping system by keeping away from overheating. In that regard, your stage about carrying additional insulation layers below your sleeping bag is perfectly taken: that additional layer makes a further temperature gradient in between you plus the insulation in the bag, earning condensation inside the bag (or maybe in your levels) far more likely. I’ve observed that, In most cases, trusting the bag to maintain you heat down to its “ease and comfort rating” with small or no levels, as complicated as it may seem once you initially enter into a frigid tent, pays off ultimately, and will usually end in a comfortable night’s snooze while not having to take care of a moist VB liner, and with little or no condensation Within the bag.

But this time all I extra was The three oz HH kidney/torso pads down under the usual OCF hammock pad. On best I used a down 21 oz Golite top rated Quilt(TQ). They originally rated it at 20F, but quite a bit of folks stated which was definitely optimistic, and I observed their more recent models at precisely the same excess weight and size were being rated at 40F, so who understands. I generally thought of it for a 30F TQ for me. I also had the vented more than go over for that HHSS, so I was in a very sock more or less, but no tarp. I also experienced a “frost bib” fleece jacket hanging down in the hammock’s ridge line to capture a few of the condensation from my breath. Clothing was SWL VB shirt, gloves and socks as initially layer, and slender lengthy john trousers with north face GTX clone/WPB rain pants around that to function fake leg VB ideally, and my eight oz BMW Polarguard pants over that. and also a fleece jacket and a thin layer in excess of the VB shirt. Also wool socks and PG booties about the VB socks. as well as a JRB down hood to go along with my TQ. following a number of hours, I additional a torso duration bit of Walmart blue CCF pad(sit pad which i constantly have with me) beneath my legs, to deal with a slight chill underneath my calves, but largely to deal with an awkward calf ridge that had formulated- pad solved both problems.

Given, Im even now in round Naive.0 of my open sourced conceptualizing but I can’t shake the urge to equally theoretically and pretty much tinker about With all the eyesight of VBL and non-degradable sleeping devices during the context of extended forays in to the freezing wild.

(with no VBL, perspiration would go away from your human body and through outer levels (if relevant), then with any luck , evaporate in the ambiance.) This entrapment of humidity has three Advantages:

If this type of mechanism exists, then VBL would preserve h2o and electrolytes, as well as human body warmth. clearly from what you report, under major workload this putative feedback system will not be adequate on its own to regulate sweating adequately. Most likely, nevertheless, such a system could make a significant variation for the duration of small exertion periods for example sleeping.

one particular concern is this may lock in a lot of vapor. I Usually rest in just a foundation layer and vent the bag when I get heat. garments, and h2o bottles are saved from the bag to circumvent freezing in the evening. Leaking water bottle a possible but to this point hasn't happened.

VBL’s can be found as content articles of clothing—including socks, gloves, pants, jackets/shirts, and vests—and as sleeping bag liners. Later in the following paragraphs I'll tackle the positives and negatives of the varied VBL fabrics and kinds.

I am also serious about using it for a lot more athletic, Unwanted fat tire trail Using. But I don’t definitely care about remaining sweaty soon after All those rides.

certain it received’t penetrate my fleece or down jacket, but what occurs to it then? I get that get more info VBL is very best suited to pretty chilly environemnts and problem, but go ahead and take Ski example. This was extremely perfectly described, I've knowledgeable everything my lifetime to be a Skier, once the Sunlight drops down driving the mountains, the temperatures fall dramatically, and you have seriously chilly in a short time as your dresses are all wet from the day’s intensive skiing…. but if i had been putting on a VBL, whilst skiing, I’m very confident it would've prompted me to sweat a good deal far too, if not more, then exactly where would All of this sweat go? Or is the concept that basically we assume that I would have taken out sufficient of my gear during the day that I wouldn’t have sweated?

I simply put some low-priced pocket heaters inside my socks, stuffed them from the toes of my boots, then stuffed my mittens inside. twelve hrs afterwards, my boots had been still warm.

Vibram has not too long ago unveiled an insulated ascent model. however, these aren’t water resistant, so I’m hoping a VBL will address this deficiency. I would then pair these with Kahtoola KTS flexible crampons, and voila – a lightweight mountaineering Option for summer months climbs.

It grew to become immediately clear that my sleeping and clothing program, which was simply just a warmer Variation of a standard lightweight setup, failed to adequately take care of perspiration and loft-reduction.

If you utilize a VBL bag liner, on the other hand, it is possible to only slumber as part of your foundation layers, and at best you are able to keep the garments within your bag but outside of the VBL.

Our bodies are built to shed a specific volume of humidity, even though sleeping instead of overheating. As a result, in my view, the exceptional sleeping system is one which allows for this kind of “regime” moisture reduction without compromising its insulating Qualities.
