Hi bpl this is my first post and I am pretty much a complete noob to light weight backpacking and have basic hiking and camping skills gained from bi-yearly 2-3 day summer/fall backpacking trips in the Shenandoah. That said, I have spent the past two weeks lurking and reading as much as I possibly can (Articles read and detailed notes taken: WP/B fabric technology, Revisiting wind shirts, science and breathability of rain gear, high exertion moisture accum, clothing and sleep systems for hiking, winter backpacking comfort, as well as numerous reader gear reviews and posts and the book is on its way to my house right now). That said, there is nothing that beats experience and at some point I need to finalize a gear list and do some backyard winter camping & low-risk overnight backpacking trips. I really enjoy the outdoors in the winter, nothing beats a silent forest covered in snow :)
As far as I can tell by looking at wunderground and other weather sites, plus my limited experience with Shenandoah winters, the conditions I will be camping in include:
Temps: mid-teens – 40s
Unforecasted rain and snow are both probable however I would avoid backpacking during forecasted snow or rain storms.
I am not sure of the overall relative humidity of the Shenandoah during the winter months. Any additional advice in the area of climate would be greatly appreciated. The trip length I would like to achieve comfortably would be 2 to 3 nights. Avoiding the dead of winter and/or extreme forecasts (being able to survive an exceptionally cold/rainy/snowy night is obviously required). On top of all of this I am focused on informing myself to the best of my ability and packing exactly what I need to be comfortable. I am extremely intrigued by the philosophy of backpacking light as it matches a similar agile philosophy I live my life by.
That said here is the clothing/sleep gear I have. I would appreciate any/all suggestions on what clothing/sleep gear I still need to acquire/test and also what additional material I can read to further learn about how to make decisions on my own about what gear to get and how to use it properly.
Base:
EMS Techwick 2 long sleeve shirt w 1/4 zip
EMS Techwick 2 pants
Pants:
Beyond Clothing Cold Play Shock
Sleeping Bag:
Montbell #3
Sleeping Pad:
BMW TorsoLite
Tent:
Tarptent DoubleRainbow (+1 girlfriend)
Clearly an incomplete list ;)
1. The beyond pants + base layer should provide adequate leg insulation while active.
2. I need torso layers for wind, insulation, and rain.
3. Would it be possible to hike during the day in 20-40 deg weather in nothing but my base layer and a wind shirt? Much of what I have read has led me to believe this is possible/common. I was thinking about something like the Houdini.
4. Hiking during freezing rain is not something I am into so hunkering down during a shower and/or slowing down my pace while wearing a rain shell reduces the need for more advanced breathability. I was thinking of something along the lines of O2, Precip, or DropStopper.
5. That said, would it be possible to replace my wind and rain layer with something like a Patagonia Specter, GoLite Virga, or even something as flashy as an ID eVENT? Would those types of jackets provide the additional protection against evaporative heat loss to allow me to hike in nothing but it and a base layer (in the event the houdini wouldn't cut it)? Is that wise given my inexperience?
6. While in camp I would need an insulation layer and based on what I have read I was going to go with a synthetic high loft based garment based on polarguard or similar (suggestions?).
7. My sleep/tent system poses a few problems: down bag rated to 30deg inside a single-walled tent in possibly humid winter conditions is overall a terrible idea unless I take the right precautions. Below are some of the things I can identify.
8. My bag will need to be protected from condensation. Do I need a vapor barrier? Where can I find more information on vapor barriers (as this is one of the areas I have done the least research, but have read as many forum threads on the subject I can find)?
9. Assuming I determine an appropriate way to keep my bag loft dry and wear my base/insulation layer will my 30deg bag be warm enough? I sleep hot and love to sleep cold. I don't sweat a lot in general.
10. The above concerns are potentially compounded by the fact I have a single wall tent. Will this shelter combined with my torso pad and using my backpack as ground protection for my legs be adequate? What else should I add?
I realize this is a TON of information. If 25% of this gets addressed I will be exceedingly thankful. If this is way to noobish of a post and there is stuff I can read to answer this on my own please do not hesitate to point me in that direction before taking time to answer. You can be assured I will continue to read as much as I can on my own. Thanks, and this site/community rocks and has me seriously excited about getting out and camping light!
