    I had several days last December that were Similiar to your experience though the low temperature was in the teens vs below zero. Echoing what others have said.
    1) When it's above freezing reduce the amount of clothing potentially getting wet. I now have a complete lightweight base layer, cap1 that I will wear with a cuben rain suit. Will the base layer be damp, yes. Does it hold much water, no. Also, I agree with Rogers comments about hiking warm. I can go down to freezing with base layer plus cuben. If I stop, then I have to quickly put on insulation.
    2) Just below freezing and dry conditions are very straight-forward. Again, I dress cool so that I don't sweat and moderate ins entity to reduce getting moisture.
    3) Still colder then I go back to wearing the rain suit as a VBL over base layer and then minimal insulation as need outside.
    4) I don't dry anything inside my bivy. No reason to introduce moisture into sleep system.
    5) VBL at night. I have had great luck with VBL even when used above freezing. I have found that I sleep much warmer and it has completely eliminated moisture in my quilt. I am still playing to see the warmest temperatures that I can wear a VBL with only a base layer. I suspect that it will be as high as 40-45.

    Dave,
    I appreciate your suggestions, and even more importantly, the manner in which they were offered.
    Thanks

    Greg,
    I suspect you and I have very similar styles. Thank you for the comments.

    Ike, you did well to make it 4 days through conditions like that without any more damage than a somewhat damp quilt. I imagine that on an hourly basis you were making adjustments and gear/travel decisions that largely worked out great. You seem to be developing solid winter skills and I admire the way you're willing to get out and go for it, even solo in winter. Experience and experimentation go a long way in figuring out how to be comfortable in these conditions.

    I have been spending time traveling on the SHT in winter (Minnesota's North Shore, presumed to be similar conditions). Since any given week can have temperature swings like you described (though I haven't seen those swings in a 48-hour period, either), I've decided I need to be prepared to travel in rain as well as frigid cold. For me, this means bringing at least light WPB rain gear along. I've experimented with traveling while wearing VBLs and never found the sweet spot. A base layer, possibly wind shirt and light rain shell is a bit easier for me to figure out: I'm warm enough when i travel, and though I do get damp from sweat, i typically can dry from the inside while i'm on the move. I felt like i would get drenched in VBLs, but that might just be lack of practice. Some of my best practice for cold rain was actually a week in scotland a couple years ago with highs in the 30s-40s and lots of wind/rain. Making sure I was on the cold side while moving kept me from sweating too much. I used an eVent shell for that trip which impressed me.

    As you alluded to, a drying fire (or nalgene filled with boiled water) probably could have extended your trip without making any gear changes. That said, I'd be looking for ways to avoid holding my expensive winter bag up to a fire! It seems you bring a remarkably light kit for the conditions you face, so you probably could add back a bit of weight without issue. Most of my trips are 2-3 days, but if/when i do a 4 or 5 night trip i think i'll still bring WPB shells but also bring a 4 oz sil VB sleeping bag liner to prevent loss of loft/weight gain of my bag.

    Finally, some conditions are just tough. There are times when there is no shame in just setting up your shelter for an hour or two: make hot drinks, listen to your ipod and let the worst of it pass. I used to guide long paddling trips and judicious use of breaks for bad weather were great for morale without slowing our pace overall. Knowing when to take cover is important.

    thanks for all your contributions,

    Matt

    Of the two WPB laminates I've found eVent is easier to clean the "body frost" off of the back after use. Once the frost is shaken off well the REI Kimtah parka again breathes fairly well.

    My GTX PacLite parka just won't release the frost on the back very well and breathes less well in any situation, cold or warm. Both parkas have good DWR, FYI.

    Thus, for very cold weather (10 F. of lower) the use of WPB laminates may not be the way to go.

    Agree. I use EPIC (Malibu) fabric for that. Can be very UL.

    I was thinking about your trip comments today at work, and realized that being an old timer, we used to use the hot water bottle trick regularly on winter climbing trips. We were always wet, cold, and out for days on end trying to climb something. The best part of our nights was melting snow, and filling nalgene bottles with almost boiling hot water. Two bottles, one at your feet, and one either in your groin, or on your chest, would raise your body core, and about blow you right out of your sleeping bag. We would move them around to warm whatever needed warming. They would literally stay hot until the next morning.
    You did really well it sounds like, and with the ability to have a fire, the hot water bottle might help with heat and drying within your sleeping system. I've used VBLs to sleep in in the past, but it was usually in very cold sub zero temps, and your body went thru a sweat, then cool, then regulate kind of phase while wearing them.
    Sounds like a killer trip with plenty of great stories for later!

    One lesson I learned long ago was to go to sleep slightly cool. Even if I thought it would get cold I would add layers later rather than overheat early. This reduced condensation in my quilt. So…… If you have hot water bottles, won't that increase the amount of perspiration you give off pushing moisture into your sleep system. Seems like it would help early but possibly hurt later. Thoughts?

    youre right that you dont want to sweat more …

    the hawt nalgenes assume that your bag is already a bit damp and losing insulative value anyways, and you need to start drying it out … or you need more heat … also the more you wrap the nalgene in, the longer it will last and the less immediate heat there will be

    which is why its more a bandaid than a solution … but IMO better than a fire unless you are in a rescue situation … you dont risk burning the bag

    putting a synth layer over the down is the way to go IMO … as i indicated this would ideally be a synth overbag/quilt … or even a synth/fleece jacket over the bag …

    i think the main lesson isnt just how to prevent your down from getting wet … because some experienced people have ended up with damp down regardless of the cause … but also how to salvage and deal with it once it happens

    Greg,
    I don't think that the hot water bottles readily pushed clean thru to persperation, but more so they were an avenue to up core temps. While climbing all day, even with paying attention to liquid intake and calorie intake, one typically ends up with a deficit. Couple that with a stop of effort, ie the camp scene, and the temp drop in extremities, and the onset of hypothermia is a given. By boosting the core, it just helped to regulate the energy you were still using to get your body warmed up for the long night ahead. Also, the overall warmth within the clothing shell, and sleep system "shell" helped to push dampness out. I can't remember the technical term for moving the moisture. Isn't there a term for moisture taking the path of easiest movement etc? Using the heat helped facilitate this. We were able to dry out a lot of layers using this kind of heat. It could have been a very viable method if another day, or even two was needed before it was imperative to dry something completely saturated and unable to insulate.
    Hard conditions regardless. Many of us old guys still suffer from cold feet from our not the greatest but it was what we had footwear of old! Gives us the chance to tell lies about the good old days! :)

    I'm not sure if a nalgene full of boiled water would lead to net removal of moisture from a bag while you are sleeping, but it would if you placed it in the bag for an hour or two before you go to bed. For example, arrive at camp, set up your 'mid and boil your first batch of water. Put the hot water in a nalgene and then place that (possibly inside a dry sack) in your quilt wherever it seems to have lost the most loft. While you are making dinner, taking photos around your campsite, fiddling with the bushbuddy or enjoying a Superior Jack the heat will force some moisture out, hopefully leaving the down quilt dryer/loftier by the time you're ready for bed.

    Leaving the hot water in your footbox overnight while you sleep probably won't do more harm than good as long as you remove enough layers elsewhere that you're not sweating more than you need. Plus, there is the added bonus of having lukewarm water to drink in the morning.

    Ike said… “Put on damp base layer bottoms with shell pants on top. Put soaked base layer top on top of R1 top and hiked until warm and dryish, then flipped them and hiked some more. By 11 am, all clothes felt dry and warm to touch…. Slept in baselayers, shell pants, windshirt, and R1. By 3 am, I was noticeably cooler. Over my lower half where the quilt was still in the bivy, ice had formed between the two layers but loft was maintained. Over my torso, where I had pushed back the bivy to promote ventilation, baffles were damp and almost completely collapsed… Back home, quilt once thawed was very damp.”
    I’m no expert, but I’m guessing that this is the point of major error. The “baselayers, shell pants, windshirt, and R1” had all been soaked at one time or another, and even though they “felt dry” they almost certainly had lots of moisture still inside them. As bearbreader said: “3. sleep with any damp clothes OUTSIDE the bag.” [BB, do you get inside a pen with bears then breed with them?] You THOUGHT you were following this rule, I think, but the fact your clothes “felt” dry might have fooled you, and this might be the key error.

    I have a light layer of insulation in my bivy to help move moisture. It also adds 15 – 20 degrees of warmth. Condensation is less of an issue with this approach. A wood stove in a pyramid does wonders for drying out gear and making you feel warmer. It does add weight but is often worth it. Alternatively, a second skin in a pyramid often adds about 10 degrees and minimizes any condensation problems.

    I had an awesome winter season, getting out for trips at least every two weeks. We had some unusual weather this year, with a fairly high percentage of days in the 25-35 F range with mixed precipitation. This gave me ample opportunity to tweak my system, one variable at a time.

    At the end of this, I came to a number of conclusions:
    1. Condensation is inevitable in cold, high humidity situations (temps 27-35 F with snow on the ground and mixed precipitation).
    2. The single most effective management strategy for me was a light synthetic overquilt. Although I've been a happy bivy user (in floorless shelters) for the past 5 years, I have adequately proven to myself that a synthetic overquilt will do a far better job of preserving loft and minimizing moisture in my down than a bivy would under similar conditions. Weighing the down quilt before and after each trip, I was able to limit water weight gain to less than two oz. The shell of the down quilt was never even slightly damp as when using a bivy, and any dampness in the synthetic was far more likely to dry in a breeze, even in subfreezing temperatures. If not, it was easy to isolate from the main quilt when packing.

    A few less important observations
    3. Lighter quilts and 900 fill down very quickly reveal weaknesses in technique compared to the monster -20F WM bag I used to use.
    4. I am very sensitive to people snoring nearby. Snores carry well over snow and ice.
    5. Gaps at neck and sleeves on a typical silnylon raincoat diminish its effectiveness as a VBL. Some cinching mechanism is required.
    6. If using a bivy, pad on the outside does decrease condensation on the bivy floor compared to pad on the inside.
    7. For a tossing and turning sleeper, getting clothing to stay put on top of your quilt is an exercise in frustration, particularly when all your insulation pieces are pullovers.
    8. Hot water bottles might help in a crisis, but shouldn't be needed if you have a sleep system that works well.
    9. Using the synthetic overquilt over a down quilt inside a bivy protected the quilt but still resulted in more condensation than when no bivy was used.

    Thanks to everyone for the feedback. The overquilt idea was a simple, practical, and lightweight solution to my problem. Hopefully this will contribute a very small piece to the Steven's question "Is there a consensus on the ideal temperature and precipitation range of a water-resistant breathable silnylon-type bivy?" I'll continue to use mine for 3 season use, particularly when opportunity for drying during the day is likely, but can not justify bringing it on multiday winter trips anymore.

    Hey Ike,

    I was toying with the idea of a synthetic overquilt myself this year, do you take ear plugs on your trips?

    I couldn't be happier with the MLD spirit quilt 48 I ended up getting.

    Earplugs- no. I wouldn't want to drown out the night time noises (coyotes, falling rain, insects, tree frogs, etc). It is very much a part of the experience for me, and I've come to accept the fact that I'm going to be awake for some part of every night. Usually, when I am awake, I'm content to snuggle in my quilt, just grateful to be out. Besides, I'm usually not around people.

    It is is nice to fall asleep listening to ambient noises, I got in to the habit of using them back home if camped in exposed spots where the wind striking the tent fly can be very noisy.

    Sounds like you have your winter kit dialled in :-)

    I recently purchased a 50* Synthetic quilt from EE for these same purposes. It arrived a couple of weeks ago but our (rare) cold winter storms are already done until next winter, so I won't get to try it out coupled with my Katabatic quilt(s) for about 8 or 9 months. Oh well, it will work well as a warm weather summertime quilt by itself too.

    > some experienced perspectives about how you would handle these conditions.
    IF you can't get/keep your sleep gear dry, things are grim. Short answer: go home, or at least retreat to dry warm shelter. You are not fighting WW III.

    Some people have suggested that you MUST stay dry. Nice idea, but fairyland. Sometimes you can't do that. Just not possible. Accept that and move on.

    Cheers
