I just did my to start with “Deep Winter season” tenting excursion this earlier March plus the temps had been 19F during the day and bottomed out at -17F throughout the night. I was interested in hoping to incorporate your notion of a VBL to aid increase my gear and minimize my In general pack fat. nevertheless, VBL attire is usually pretty high-priced and I’m not that gifted On the subject of earning my very own apparel.
But this time all I included was The three oz HH kidney/torso pads down beneath the usual OCF hammock pad. On major I utilised a down 21 oz Golite top rated Quilt(TQ). They originally rated it at 20F, but lots of folks reported which was genuinely optimistic, And that i found their more recent versions at the same weight and measurement were being rated at 40F, so who is aware. I usually considered it as a 30F TQ for me. I also experienced the vented over include for the HHSS, so I was within a sock more or less, but no tarp. I also experienced a “frost bib” fleece jacket hanging down from the hammock’s ridge line to catch a number of the condensation from my breath. outfits was SWL VB shirt, gloves and socks as 1st layer, and thin extensive john pants with north experience GTX clone/WPB rain trousers above that to serve as faux leg VB hopefully, and my eight oz BMW Polarguard pants more than that. as well as a fleece jacket and a thin layer more than the VB shirt. Also wool socks and PG booties over the VB socks. And a JRB down hood to select my TQ. following a several hrs, I additional a torso length piece of Walmart blue CCF pad(sit pad which i normally have with me) beneath my legs, to cope with a slight chill less than my calves, but largely to manage an not comfortable calf ridge that had produced- pad solved the two challenges.
when, making use of this exact TQ at about 11F, but donning thicker layers under it, I had to bail out and acquire a thicker TQ. Part of the condition was many breath condensation on my Golite TQ near the neck region. But I'd by no means long gone reduced than 14F utilizing my HHSS, and constantly experienced much more included insulation down below the hammock, and was in no way this warm. I credit history section of this good results Together with the HHSS around cover including heat on best, in addition to the frost bib catching loads of the condensation. having said that, thinking of how heat I had been- top rated, again, butt, and feet- at my least expensive ever temp inside a hammock, I have to believe the SWL VB garments was a huge, significant enable. In both equally heat and dryness. I had been also pretty comfortable with no feeling of moist Within the VB, apart from my about heating ft. I don’t Believe I at any time listened to Anyone else complain of about heating feet at 6F within a hammock. anybody? The SWL VBs might not happen to be all the reason for that warmth, but I am convinced they ended up An important element.
Their rationale didn’t make sense to me in the slightest degree, but I suppose I’ve also by no means finished a polar expedition.
ordinarily with a foundation layer of merino wool also. Of course, you wake up simply a bit damp, but as soon as you can get out from the sleeping bag, the cold dry air whisks that extra moisture absent shortly. you could place the remainder of your standard outfits on devoid of compromising it with humidity.
according to daylight temperatures and photo voltaic energy, you might or might not manage to dry the insulation. I wouldn’t depend on it on a visit in MN in January, but AK in April, that may be additional probable.
That is all seriously interesting even though, I recognize that I will try and master effectively about VBL so I can place it to check at the earliest opportunity….
Bill Kline on December eighteen, 2016 at 2:twelve pm For toes, VB socks. For breath, Considerably harder, what has labored well for me so far is a thing generally known as a frost bib. I usually am vaporba.com inside of a hammock under a tarp, that has a nylon ridge line over me. From this hangs a piece of fleece which has a head gap( put your head through the hole, then the fleece hangs loosely concerning you chin as well as ridge line. Or, I've skipped the head gap and just kind of tucked it somewhere about my neck. At six*file inside a hammock include/sock, (no tarp)with a couple of six″ diameter breathing hole a handful of inches from my confront, using VB garments, another early morning everything Within the sock was dry.
In such a case, moisture made by the body would not enter the insulation (in the morning, the amassed interior dampness might be wiped dry by a lightweight towel to then be frozen accompanied by a defrosting-by-shaking). dampness from any resource outside of the bag’s exterior shell couldn't enter insulation.
Furthermore, it appears to be that many people- completely educated in some great benefits of breathable equipment- only will not comprehend the notion or science of VBs made use of at or really close to the heat skin degree. It seems to me that science presents us/them 2 decisions: Our overall body sweat(liquid) can evaporate to vapor- leading to evaporative cooling- off of our skin and travel into our insulation, or sweat can be wicked into our insulation in liquid sort as It could be having a sponge. Which keeps our pores and skin experience pleasantly dry! Our overall body vapor(not liquid nevertheless) simply travels into our insulation, and we/they hope that the vapor(neglect sweat, previously liquid) will carry on going for an inch or three or four and NOT encounter the dew position Within the shell and condense back into liquid. Hopefully, that vapor will just continue likely earlier that breathable shell into your atmosphere which could by now be 100% humidity(vapor travels from substantial humidity to reduce, ideal? Not from reduce(close to the pores and skin to better- outside the shell maybe already a hundred%). That is the objective, and in some cases it works perfectly, Even though they are still handling evaporative cooling for the pores and skin stage. If it doesn’t function correctly most of the time, then night right after night time, some vapor hits the dew issue and condenses into liquid, or their sweat receives absorbed into their down, and loft decreases day just after working day, if no Sunlight is handy for drying. often all of this freezes into ice Within the down!
after I was hiking that has a very long sleeved cotton shirt in excess of my VB shirt. I'm able to’t keep in mind the temps, but not terribly cold, but cold enough which i might have Typically essential a little something over that cotton shirt. (yes, I'm sure, cotton, but I was day hiking close to property, and was not worried). it absolutely was obtaining late, and I had been inside a hurry about the return excursion, climbing as rapid as I could. I could notify I had been around heating, and must have unquestionably removed my shirt, but I didn't trouble, did not take the time to prevent and take away it. I just pushed on thru, and eradicated it when I obtained again to my automobile. I had been very soaked with sweat beneath my Stephenson’s VB shirt. which isn't enjoyable not surprisingly.
it can be fascinating to read the critics on the vapor barrier tactic who have never truly knowledgeable the outstanding performance at sub zero temperatures. In all it provides the benefit of preserving the insulating capability of down by holding it dry, and minimizing the amount of insulation required Total by blocking the cooling effect of insensible perspiration. Using a mild layer of synthetic extensive underwear, then a light-weight rain accommodate, accompanied by hefty fleece my summer body weight down poor supplied greater than enough insulation to help keep toasty heat at zero levels. An impressive performance. For the individuals with chilly extremities, ft and hands, even anything as simple as a bread bag around a liner sock then a heavier insulating sock is likely to make your toes come to feel like they are being warmed by a wood stove.
to start with, many thanks for your time and efforts looking into, experimenting, and publishing your findings. I'm new to climbing, two many years, and area mountaineering the AT. I seem to be gravitating to off-time hiking steering clear of the crowds. I hiked the first weekend in March at about 1500′ in sleet and slept in a very thirty degree down bag, REI Bivy, with my artificial foundation layer and awakened 3:00 each morning due to the fact I was moist and very chilly. The bag was damp on the outside, my foundation layer was moist on my skin and inside of the bivy was slippery damp. Fortunately, I had been near a city and was ready to make it into a laundromat and dry almost everything that morning. very last yr, I hiked Vermont for every week in late August beneath soaked conditions, feet ended up damp The complete time but was wearing wool socks and I never felt not comfortable.
when it comes to building a private vbl method, would some thing like lighter rain equipment work for just a vbl jacket and trousers? Something like Marmot precip relates to mind. reasonably inexpensive and a straightforward approach to try out a technique to find out if it satisfies anyone.
