Ok this is my first down jacket I've ever bought.
I'll be starting ~March 28th. I have a Summerlite (WM) and a bivy and whatnot but I want my jacket to supplement that so I can go colder. Basic stuff.
Which is going to take more insulation (pertaining to the down jacket)? Taking my sleeping system rating down 10 degrees, or keeping warm at camp?
I feel like its either the Montbell EX Light or the alpine light. And I think the answer is to get the ex light, but I lack in natural insulation (I'm skin and bones) and adding extra beef could make my trip more pleasant. (However, going overboard on it for no reason would go against all my hard work to shrink my pack weight)
I feel like the down jacket is were I want that extra beef too. Down is most weight/warmth.
My clothing layering system might be like this:
golite T (3oz) -> midweight LS/hood synthetic (havent got yet) -> Windshirt (3oz)->DOWN
I really like the WM Flash Hood jacket too.
How does everyone feel about hoods? I kinda want one. Recommended? Does it matter?
Keep in mind I'm doing a thru-hike too. My insulation will most likely be ~80% rather than 100 many nights as you all well may know.
PS. if your going to tell me I should get a thermawrap instead, then I'm sure it works great for you.Jan 2, 2012 at 10:14 pm #1818985
@namaniacLocale: SoCal-High Desert
you may be able to get away with a beefier down vest….although ive heard really good things about both of the jackets your looking at, i think you may be able to get away with a vest along with your fleece + baselayer + rain shell around camp…Jan 2, 2012 at 10:37 pm #1818995

i think the flash is super warm for the weight, and the hood, pockets, hem and extra warmth definitely justify the extra 3 oz over the ex light. I don't think its worth buying a big puffy like the alpine light. Also, the flash paired with a wind-shirt should be about as warm as the alpine light. I'm pretty convinced that the quality down in WM garments makes a significant difference in warmth (honest fill ratings). It sounds like you are plane not interested in a synthetic, but if you do decide to look that route, check out the rab xenon. I think its hands down the warmest and lightest in the category (light weight synth hoodies.) My size large is 11 oz. IMO, its a more functional garment for an AT thru hike, as you'd be more likely to hike in it on cool mornings and evenings, deals with moisture better, and doesn't sacrifice much warmth compared to similar down garments. Also, the shiny shell material looks like something created by NASA. Very astronaut chic.Jan 2, 2012 at 11:11 pm #1819001
what is the temp range yr expecting in camp (not sleeping but outside the bag)
the summerlite is a 34F en-rated male comfort bag …. a puffy sweater and pants can add ~10F depending on the amount of down/synth fill
since you are a member you can read the reviews on the SOTM reportsof down jackets to get an idea
edit … temp ratingsJan 2, 2012 at 11:39 pm #1819012
10º for a bag is tough when you're adding insulation to only your torso. IME, a down sweater will add ~5º and your bivy will also give you ~5º so you're set in that regard.
The WM Flash is a wonderful piece, top-notch quality but a bit of a strange fit. Also, expect higher weight (WM's garments are always overweight, I don't know if this is from overstuff, but be prepared).
Feathered Friends makes a lightweight jacket/hoody that should also be great quality, and the fabric they use on those is supposed to be better against the elements.
Lots of choices in the ~3oz of down range. As Eric mentioned, the SOTM report is excellent and there are very few additions since it was published. Montbell's EXL and UL will be a bit less warm, but might be enough for you. If Eddie Bauer runs another big sale on First Ascent, you won't find a better deal anywhere else (the $29 costco down jacket comes close).
I recommend looking at a hoody, the extra weight is well worth it. If not, the Black Rock Down Hat will be lighter than just about anything else and warmer.Jan 2, 2012 at 11:55 pm #1819019
Nicholas: I will say that I could see me going overboard on the torso layering. I would do the rain jacket thing you said but I use a poncho/tarp :). I don't usually sport it less its rainin.
Serge: You make a good point with the Xenon. I think I would rather get an 11oz down jacket tho. Just feel like the down would be warmer despite the conditions. I want to know what you think about this. Part of me wants to swim upstream on this one just feels right. Although it sounds like you have tons of experience with both and I have none. I like WM too! I wish I bought that flash you sold.
Eric: Temp range in camp could be 30-60 degrees within a period of 30 days. I've heard 36 on the summerlite too. And I read that article but I'm just looking for something a lil bit different.Jan 3, 2012 at 2:24 am #1819029
Is there a reason you went from considering the EX light to the Alpine light and skipped the UL Inners?
I have the Montbell UL Parka and while it's nearly an ounce under spec, it has more than replaced a heavy 300 wt fleece. I find the hood is excellent at keeping in extra warmth (I used to under appreciate head wear's insulating value) and have been toasty walking around town in sub freezing temps.
Regardless of what you settle on, I would highly recommend you get something with a hood. It may be the single most thermally efficient design feature of any torso insulating product. Protecting both the skull AND the carotids from cold allows some much more hot blood to be sent to the extremities.Jan 3, 2012 at 5:45 am #1819044
Given we're getting a very late start to winter here in the SE and it was 7F with wind when I got up this morning, I suspect you'll see temps a lot colder than 30F at elevation with your dates. You may even find yourself post holing in the Smokies. IIRC, people were finding a fair bit (feet) of snow there in May this year. I'd start out with a bag/quilt rated to at least 20F and take something pretty warm for camp wear (at least 4 oz 800+ fill).
I'm not "skin and bones" but I do have a lean build and quite low body fat percentage, which leaves me easily chilled. I find myself cool to cold in the low-mid 40s with a 60g PL1 hoody. Something like the UL Down Inner parka might get me to the low-mid 30s (more likely mid). In fact, it took a UL Down Inner jacket + a 60g PL1 hoody to get me in to the high 20s/low 30s last year. For anything lower, I have a Rab Infinity Endurance. My small is 14.8 oz and should keep the avg male in typical layers thermo-neutral (warm) to 15F. If you run cool like I seem to do now, I wouldn't take anything less to start.Jan 3, 2012 at 8:28 am #1819096
+1 on the first ascent. Picked one up recently with their 50% off coupon. They should be going on sale soon in time for your march start. Well made, availabe in tall sizes if needed.Jan 3, 2012 at 8:33 am #1819101
@brianleLocale: Pacific NW
I own a summerlite, and would be nervous about starting in late March with a Summerlite unless I had a really beefy parka. In 2010 I started in late Feb with a WM Ultralite (20F rated), which was pushing it, but I carried a Montbell alpinelite parka and down booties to wear inside the bag at night.
If the bag is non-negotiable, I'd look for — well, much more of a down jacket than you'll want after the first month or so.
Really, I think that if at all possible you want to beg, borrow or buy a warmer bag to start out with, then swap around Pearisburg or so. That's where I swapped for my Summerlite and was happy with it for the rest of the trip. At that point you won't need a terribly warm jacket; I used a thermawrap jacket and was fine.Jan 3, 2012 at 10:28 am #1819151
Dustin: Idk I just felt like it was one or the other. Perhaps I'm too black or white.
Chris: Ya I think I could see temps down to 20 degrees. Eric asked for "out of the bag temps" and I didn't want to say anything bout the morning. Ur right on the 20 degree bag. Dunno if I'll make the switch. When you talk about "not starting with anything less" are you factoring in the 20 or 32 degree bag? Or regardless of what bag? Want to make a guess on when I could start with the summerlight and RAB infinity endurance? Thank you.
Brian: Ya I'm scared of your gear list haha. I saw lotsa warm(expensive but awesome) clothes for that hike. How hot did it get after you switched to your summerlight? Maybe not too hot b/c you started in Feb? If I start in April I could get hot in that?
Sorry for the tangent. I like "beg, borrow, or buy." And "well much more of a down jacket than you will want after the first month or so" : I kinda plan on sending the down jacket home in Pearisburg.
General Comments: Sounds like my midweight layers gona be something more like a R1 hood than and cap3 LS shirt. And thank you for helping me out.Jan 3, 2012 at 10:49 am #1819161
sam … ill say that should you take the advice of the more experienced people here with a 20F temp … youd likely want something with 4+oz of 800 down fill …. ie an alpine light
you likely want something with a hood as well, as that adds to the warmth on stops especially in the wind
also as someone mentioned, you may have issues using only yr down jacket as a booster when sleeping without additional insulation for the legs, unless you use something like a hawt nalgene, etc …Jan 3, 2012 at 11:51 am #1819189
Definitely. You could very well see temps in the 20s during the day as well. The Summerlite wouldn't be enough for me below freezing alone and probably wouldn't be enough below the low 20s even with something like the Infinity on.
Unless you plan on doing the wake up, hike all day, go straight to bed thing you need to factor in clothing to keep you warm while sitting around and chatting with others.
I'd start with a 20F bag/quilt minimum or wait until early May. I'm actually planning to try 0F-10F quilts out over the next few months as I'm not even sure my 15F WM Apache will be enough for me in winter here.Jan 3, 2012 at 12:51 pm #1819233
@jeepingetowahLocale: South Central
I did 1500 miles on the AT in 2011. I took along my MontBell UL Down Inner Parka. The greatest, the awesomest.
PARKA, PARKA, PARKA! Don't skimp, get a parka.
7 oz for the whole thing, should be fine.
2.5 oz of down or more would suffice.
IMHO… meet those criterium, and I don't really care who makes the jacket honestly.Jan 3, 2012 at 4:31 pm #1819337
Wallace: What degree bag did you start with and when?
Chris: I will factor in keeping warm in my clothing while at camp… Temps in the 20s during the day!?… How many nights in April you think it's going lower than 20 degrees?… I believe I've been in colder temps with my Summerlite than early May. Thanks for helping me. Sometimes you gotta tell people things they don't want to hear. I'm dealing with this post traumatic stress.Jan 3, 2012 at 4:51 pm #1819346
It's honestly very hard to say as it varies year to year. You *might* be ok assuming you aren't moving too fast.
If it was me, I'd expect to be to Clingman's Dome by mid-April. At the higher elevations, it looks like temps avg high 20s to high 30s for April days and mid teens to mid 20s nights. May averages 8 to 10 degrees higher. I probably wouldn't expect it to be much different for GA and the first part of NC.
As above, it can vary widely. Ex. It's January – Mt Mitchell is showing a wind chill of -20F tonight and we had close to 0F wind chill in Asheville today. Yet Friday is supposed to be back to the 60s during the day.
Worst case, you wind up with warmer insulation than you really need and can change it out along the way. If you do go under insulated though, and make it to Mountain Crossings, you're going to pay a fortune to buy something you probably could've gotten a lot cheaper ahead of time. :-)Jan 3, 2012 at 5:06 pm #1819362
I notice you "put aside" the idea of a MB Thermawrap.
I have to wonder why?
I just hiked the AT last year.
I started March 15th and finished June 21st.
The coldest temperatures I saw were in the Smoky mountians where it dipped into the low 20's a few nights.
The biggest weather related factor I had to deal with on the AT was rain and moisture.
Here is what i used from Amicalola to Katahdin:
Columbia Long sleeve Titanium Shirt.
US Army surplus PT shorts.
Lightweight Smartwool long john bottoms(Bounced at Pearisburg, had from Hanover NH to Gorham NH then donated to hiker box).
Montebell Thermawrap Parka.
Patagonia Down sweater(had from Amicalola to Pearisburg, bounced to Hanover but donated to angel there).
TrailLite designs cloud cape (used as VBL)
Home Made fleece and nylon mittens.
Katharina's Baby Alpaca wool knit hat (Gave to a trail angel in Hanover.. she was a nice angel!)
Columbia Sun Visor
Wearing all these clothes I was just comfortable into the lower 20's using an MLD 30 degree Spirit Quilt.
I used the quilt the whole way.
The only thing I bounced was the Patagonia Down sweater at Pearisburg. I actually gave the sweater away in Hanover to a trail angel cause it was just plain dead weight.
A word about the Thermawrap Parka.
I met a lot of other hikers using the thermawrap jackets as well.
We all found that we could walk directly in the rain with our thermawraps and they stayed warm and even dried on our bodies while hiking less than an hour after the rain stopped.
The hood on my Parka was awesome! What ever you choose, a hood is HUGE especially for a quilt user.
I had both a synthetic quilt and parka so moisture never bothered me.
I met a few folks that had problems dealing with their down gear after the 10th straight day of rain on the AT last year.
This had nothing to do with they way they stored their bags. The moisture in the air saturates the down regardless of pack covers, liners, etc.
It might be worth considering that if your bag or quilt is down, your jacket or parka could be synthetic.
Worked for me!
By the way, you'll probably toss your gloves or mittens in Pearisburg like i did.
When you get to the White Mountains of New Hampshire you can save money on replacement gloves by doing the following:
Put a wool sock on each hand. Then cover each with a Fritos corn chip bag.
this will easily last through the Whites and over mount Washington where it was below freezing for me.
After Mt Washington it's hot and sweaty all the way to Big K. The only cold from then on occurs in the Bigelows or up high during thunderstorms. I didn't need anything more than my Thermawrap.Jan 3, 2012 at 7:00 pm #1819411
@jstewseLocale: New England
Great insight Matt. I'm planning on a slightly earlier NOBO start than you did, and I've looked over your gear list a couple of times. Did you used one of the jackets to cover your legs?
I'm planning to bring a Katabatic Palisade with +2oz. (12 oz. total) and with a Montbell UL parka, cap 3 bottoms and a z-lite torso pad over a 3/8 evazote, I've been good to 20, and I usually sleep pretty cold. I'm planning to beef up my base layers and add some down booties and an r1 balaclava for my Feb. 28 start, and bounce what I need to when I need to. I'll also likely bring a Rab Xenon rather than the Montbell for the sake of not having all down insulation.
My overall plan is to be able to be comfortable to 20, and I don't see that being a problem. Chances of seeing prolonged daytime temps of 20 or nights much below that aren't enough for me to warrant bringing a ton of extra gear that I can't afford. Being a little chilly for a night isn't going to kill you. Have a snack, do some sit-ups.Jan 3, 2012 at 7:15 pm #1819416
I used a montbell ex light and it worked great, sent it home after damascus though! I started march 19thJan 3, 2012 at 7:20 pm #1819418
Check this article out. If you don't feel like reading the whole thing, then just look at the conclusions and Fig 4.
Basically says the average degree of variance between 1500 and 5500 ft at the park is about 3-6 degrees lower with the lows and 10-13 degrees lower with the highs. But don't take my word for it: Read it!
Here are Gatlinburgs Temps for last April:((Gatlinburgs elevation is like 12andchange) http://www.accuweather.com/en/us/gatlinburg-tn/37738/april-weather/335723?year=2011
Chris: "Worst case warmer than what I need" – I might rather be cold one night in exchange for keeping my current bag/staying lighter. Brain Frankle said there are three kinds of backpackers: ones who build their gear setup to be comfortable over their most difficult stretch of hike, ones who setup up for conditions present 95% of the time, and the ones who pack their insecurities. Think its bad that I fall into the second category? Ya I don't want to buy anything at Mountain Crossing. Already looked at their website and I'm scared of selection and price. I don't plan on picking anything up there. I'll be sleeping outside a lot this winter figuring things out. Wish I had my setup more dialed in so I could test it out tonight (19 degrees in Raleigh). Thanks again Sensei.
Matthew: I have seen your gearlist as well and congrats on making it! The temps you described are more similar what I'm expecting. I like that you used a thermawrap and down. I've been out for 8 days so I kinda know how the down gets clammy. I got faith in the down, I want that to be my primary insulating layer. I would love to use a thermawrap instead of a midweight layer perhaps depending on breathability/ temperature conditions. Is that what you did? I could see it doing well in the rain that's awesome. 10 days of rain with no "halfway convenient" town/dryer/sunshine/anyway to dry out your down? Thank you for talking about it being "hot and sweaty all the way to Big K"; its nice that someone else knows I'm making it all the way!
General Comments: Really think I'm keeping the same bag. I think the start dates more likely to change than the bag. Weather might be the main factor in my departure. Who knows what I will do. If gonna buy stuff and test it out this winter.Jan 3, 2012 at 7:23 pm #1819420

Im right there.Jan 3, 2012 at 7:53 pm #1819430
@ james- I wore the Patagonia down over my Montebell Thermawrap while sleeping under my quilt for the coldest nights in the Smokeys.
The Patagucci down sweater(size large) was large enough to wear around the Montebell parka(size medium) without compressing the fill of either.
On top of those my MLD quilt covered me just fine without any gaps despite the increased bulk of me and my two jackets.
For my legs i just wore the light weight Smart wool long john bottoms. My legs don't seem to need much insulation.
I wore Kat's wool hat and the hood of my MB Parka for head protection. This was a super combo.
I also put my home made fleece and nylon mittens over my feet while sleeping those couple of 20 degree nights.
@ Sam- It is true, you can easily dry out your down in town at least once a week if not sooner along the AT.
I actually used and very much loved a WM ultralight for the PCT and CDT. However I did dry it at every opportunity on the trail.
I found I never had to worry about drying the Spirit Quilt. The apex insualtion was always warm even when wet and another thing.. The Spirit quilt would dry by body heat alone overnight. This is something my down bag never did.
Of course the best bag is probably the one you already have. Not trying to convince you either way.. just sayin what worked for me.Jan 3, 2012 at 7:56 pm #1819431
@jstewseLocale: New England
Testing is an pretty solid way of knowing what you'll be comfortable with too. Backyards are great for this. I spent a week in the Smokies in early March last year and that sort of put me at ease about the area, it seems a lot of people get worked up about it. If you're accustomed to hiking at elevation, there's nothing to be afraid of, be smart. One huge upside is the lack of exposure compared to some ranges.Jan 4, 2012 at 8:02 am #1819591
This is the bag Wallace usedJan 4, 2012 at 8:54 am #1819619
Unfortunately, the data in that study is over a decade old now. :-)
I got the variations and ranges from the NPS site. I trust the Rangers on the ground a bit more than some guy at a desk analyzing historical data. My personal experience…I did a trip in the Smokies in June 2008 and we had low 50s for highs at low elevation (around Lake Fontana). That pretty much ruined our swimming hole plans. So much for hot Summers.
Definitely no problem with being in camp 2, as long as you're intelligent about it. I guess the good thing about an AT thru is you can afford to make a few gear mistakes, since you cross a town every few days.
I think if you push back a couple of weeks, or even better a month, you'll be ok with the bag you have. Just don't forget about the Baxter closing dates and party too much along the way.
