I snooze much more comfortably in breathable nylon shelled bags. I don’t like sleeping in bivies for the same cause. I can come to feel the humidity Make up and don’t like it. considering it, I’ve professional the same point sleeping in a little car Along with the windows closed. Ugh.

But this time all I added was the 3 oz HH kidney/torso pads down below the same old OCF hammock pad. On leading I applied a down 21 oz Golite Top Quilt(TQ). They at first rated it at 20F, but a lot of oldsters mentioned that was actually optimistic, And that i found their newer models at the exact same bodyweight and measurement were being rated at 40F, so who is aware of. I always considered it being a 30F TQ for me. I also experienced the vented in excess of go over for your HHSS, so I used to be within a sock roughly, but no tarp. I also had a “frost bib” fleece jacket hanging down from your hammock’s ridge line to catch a few of the condensation from my breath. Clothing was SWL VB shirt, gloves and socks as first layer, and thin extensive john pants with north facial area GTX clone/WPB rain trousers about that to serve as faux leg VB ideally, and my eight oz BMW Polarguard trousers more than that. And a fleece jacket and a thin layer about the VB shirt. Also wool socks and PG booties about the VB socks. and also a JRB down hood to select my TQ. following a couple hrs, I additional a torso duration bit of Walmart blue CCF pad(sit pad which i generally have with me) below my legs, to deal with a slight chill less than my calves, but generally to deal with an awkward calf ridge that had designed- pad solved equally troubles.

My most loved illustration of the latter is when I utilized them even though removing ice dams off rooftops in Frisco, CO – the VBL served to attenuate evaporative warmth reduction and saved my insulation dry, which prevented me from having chilled by the top in the day.

Your comprehension of these fabrics is inaccurate. both of those are categorised as “water resistant-breathable,” that is a smoke-and-mirrors time period for a cloth that supposedly stops dampness from passing by way of it even though also allowing dampness to pass through it. Huh, what? That’s termed advertising. In reality, these fabrics do breathe, albeit not almost as well as, say, a foundation layer shirt or perhaps the light-weight shell fabrics the thing is on most sleeping baggage now. So whenever you perspire in the evening, this perspiration will pass through the internal fabric, into and ideally in the insulation, and thru the outer material, where it is going to evaporate.

at the very least the down i spend money on this tiny challenge can normally be recycled into some thing essentially useable.

a short while ago, I ordered a sleeping bag VBL produced by Western Mountaineering and find it irresistible! I have tested it out inside a 32 degree WM Summerlite bag in -9 degree climate… Here is the url to my films in the event you treatment to Have a look.

This breathable facet couldn't be on The within, adjacent on the sleeper, because dampness would accumulate In the bag from the non-breathable layer. The breathable layer could go on the surface, as well as non-breathable layer adjacent on the sleeper, but the situation listed here is that the sleeper wouldn't manage to wear any clothing to mattress In addition to a base layer. or else, perspiration would obtain inside their clothing program, e.g. puffy jacket.

If a sleeping bag doesn’t breath properly plenty of then I suppose it could start off finding major with moisture. But my knowledge in Alaska while in the Winter season was which the air was very dry along with the down seemed to get the job here done properly. Possibly I wasn’t out lengthy more than enough to notice the accumulation of H2O while in the bag.

many thanks so much for this seriously detailed and insightful write-up. I’m heading to Lapland then Svalbard in 10 times, and striving to get ready with the situations.

Additionally, it seems that the majority of individuals- thoroughly educated in some great benefits of breathable gear- merely usually do not comprehend the idea or science of VBs utilised at or pretty near the heat skin stage. It seems to me that science offers us/them two choices: Our human body sweat(liquid) can evaporate to vapor- leading to evaporative cooling- off of our pores and skin and travel into our insulation, or sweat is often wicked into our insulation in liquid type as it would be having a sponge. Which keeps our pores and skin emotion pleasantly dry! Our entire body vapor(not liquid nevertheless) just travels into our insulation, and we/they hope the vapor(forget sweat, already liquid) will carry on heading for an inch or 3 or four and NOT come upon the dew level inside the shell and condense back into liquid. with any luck ,, that vapor will just keep on likely past that breathable shell into the environment which could by now be one hundred% humidity(vapor travels from higher humidity to decrease, ideal? Not from reduce(near the pores and skin to higher- outdoors the shell possibly already a hundred%). That is the aim, and at times it works beautifully, although they remain working with evaporative cooling with the skin stage. If it doesn’t get the job done completely each of the time, then night just after night, some vapor hits the dew level and condenses into liquid, or their sweat will get absorbed into their down, and loft decreases day following day, if no sun is handy for drying. sometimes all this freezes into ice In the down!

The principal outcome of the VBL is stopping the transmission of insensible and smart perspiration, i.e. sweat, away from the human body, efficiently creating a microclimate between the VBL and Your entire body.

I was thinking about utilizing function or HyVent materials on either side. This should stop moisture from passing thru the fabric in the down. It in idea would also allow for virtually any humidity that did reach the all the way down to move thru the material Once i hung it as much as air and dry out.

It has to be a great deal under freezing to justify VBL’s. If it’s a twenty-deg minimal, it’s most likely nonetheless above freezing in the shelter.

But I thought the complete thought was to get non-breathable and trap any dampness That may occur(vapor or liquid sweat) so that you can preserve it out in the insulation? I believe as far as a VB function, it could operate just fine. They final For some time in my HHSS, but possibly would not previous long to be a bag liner, as identified.
