Bill Kline on January 28, 2019 at eleven:03 am I agree, there's nothing new in either basic principle, concept or manufacture, that I know of. I remained somewhat stunned at how tricky it's to acquire men and women to simply accept The essential science and probable advantages of this technique. less than some situations, some alternatively significant Rewards. There is an out doorway Discussion board I take part in, and I've brought up this idea quite a lot of situations through the years.
Jeff B on August 19, 2018 at four:twelve pm engaged on an suitable mitten method for Jan-March together the AT starting in Maine. with the RBH mittens, does one feel that their “Ultralight” (non-detachable liner) mitten with liner gloves is adequately warm, or would you splurge for the extra excess weight from the “Altitude” liner/shell technique?
As for sleeping conditions I’m not sure if this is doable. I’ve observed luggage with vented zippers however it’s ordinarily only When you are employing a also heat bag to the problems and need to dump warmth.
a few of the moisture will acquire inside your foundation layers, which you'll dry by way of air flow, sunshine, or A fast fire. Other humidity may perhaps freeze to the inside of the VBL, and it can be simply just dusted off.
as the temperature throughout your sleeping process is not really continual, but somewhat a gradient, the dew issue will Similarly be a gradient, and whether or not condensation will take place within your bag will depend the two on that gradient and on the quantity of humidity entering the technique (i.e. simply how much you will be perspiring), plus the porosity of your outer sleeping bag material.
I've carried out some snowshoe about night time journeys approximately 7 days in Sweden/Norway. very first journey it had been -20c in Stockholm – 25c daytime further more north and -30c some evenings when camping.
I feel I’ll get some in their socks to check – it’s excellent they've a tall Edition and it’s previously seam sealed!!
If a sleeping bag doesn’t breath well ample then I suppose it could begin receiving weighty with humidity. But my expertise in Alaska within the winter was that the air was really dry as well as down looked as if it would get the job done perfectly. Probably I wasn’t out extended sufficient to note the accumulation of H2O while in the bag.
I’d get here hypothermic Tremendous-quick if I couldn’t retain Doing the job hard. As it can be, lunch breaks may be dangerous if I’m not watchful to stop out on the wind. I’m contemplating a VP layer would be just the matter to maintain my insulation dry, however you’re expressing perspiring in VP garments isn’t enjoyment. How will you stay safe when you’re sweating difficult in the cold? Keeping my activity to ranges down to the place I don’t sweat isn’t doable.
I attempted it in opposition to the pores and skin, and my toes didn’t really feel moist or clammy till I took the outer wool socks off.
Jim Morrison on February 1, 2019 at twelve:25 pm yes Monthly bill I agree most is by way of breathing. But check out putting a plastic sheet over your sleeping bag some night. I did And that i promptly felt clammy and moist In the bag. So there is no less than an inexpensive quantity (important sum I should really say) of moisture, sensitive or insensitive perspiration, is coming out of Your whole body.
Beforehand After i winter camped with my -twenty Mtn Hardwear down bag, the moisture amassed on the surface from the bag, not the inside. Temperatures will very likely be hovering all-around zero F, possibly lessen. Humidity might be moderate. Should I use TWO VBLs in my system or just one? I won’t be using a bivy Together with the tent. If I just use just one, should really or not it's utilized within or outside my down bag? many thanks for lending your helpful practical experience! ????
for your AT in Winter season I don’t Imagine you'll need the Altitude liner, Whilst it weighs just a tiny little bit much more than the Hybrid Variation, so I’d likely just Choose it — mainly because it is artificial insulation, its warmth will lower with use.
Fred Bar on November 27, 2016 at eleven:34 am good day. obtaining accomplished some winter climbing/tenting at RMNP, I am planning to do several additional larger altitude Winter season climbing/camping while in the United states right before transferring on to summits like Huayna Potosi in Bolivia afterwards this year and Aconcagua in Argentina a while following that. certainly they are much easier to do than other mountains of the identical altitude, but to me altitude would be the primary worry (AMS/HACE/HAPE). My second concern is cold climate as I happen to be Discovering that often times a few of the expedition customers cannot reach the best due to insufficient warming of ft and/or hands and The truth that you need to do experience colder at elevation for a similar temperature at floor stage.
