(or in this case lack of layers)
If you have seen this all before skip down to "layer ONE".
I get to spend time ice climbing around Banff and on the Icefield's Parkway in Alberta Canada. Places I have climbed and skied in most winters for years. Last winter I was lucky enough to spend a few months in Chamonix.
Besides the obvious high quality ice climbing I always look forward to field testing some new (for me anyway) pieces of clothing and ideas on cold weather use.
But before I get to what I have learned in the last two years, let me back up a bit and tell you what I have used in years previously and have been happy with generally.
The coldest temps we would actually climb in hover around -25/-30C (-22F). Anything colder and I retreat to a shelter, hot springs and good food. Not uncommon to see
+10C (50F) on calm days in the sun on sheltered ice climbs.
Generally Merino wool or Capilene, two piece set ups. Some times even these will get layered.
Mid layer/insulation ?
Pile. Pick your weight and material but generally some sort of pile gear. Pile pants and pile shirts or sweaters.
Outer layer/ protection?
Early on it was nylon shells, then Goretex and then Shoeller style soft shells of wool/spandex (25 years ago) and more recently synthetics (Shoeller and Polartec fabrics) with real 4 way stretch.
Boots were singles and dbls. Often times with Supergators on the singles and even the dbls when required.
Old stand-bys were boiled wool Dachsteins with/without over mitts. My favorite were Dachsteins and Helly Hansen over mitts and when required a foam pad between the layers to keep your hands from getting too beat up with straight shafted tools. Dachstein gloves had their place as well...but generally considered a luxury. Goretex shelled gauntlet gloves with thick pile liner came next and have remained a standard with leashed tools.
Leashed tools? Leashless tools? Here is where much of the info I am relating changes drastically. Tools te newest BD Cobra and Fusion or the Petzl Nomic and Quarks have in many ways redefined what we use for clothing on ice/mixed climbs. Gear that easily works leashless will NOT be warm enough, in my experience, for leashed climbing.
OK..back to the clothing systems.
An old saying I heard as a kid was, "Eskimos never sweat." The thought behind that? It was just too cold in an Arctic environment to ever risk getting wet, soaking your insulation and then having that insulation freeze. Makes sense, but how do you ever get anything done and not sweat if you are working hard and trying to climb fast?
(I'm about to repeat info now that can be better understood by reading Mark Twight's and Will Gadd's ice climbing/technique books)
Obviously you'll sweat on the approach unless you really back off the pace. I don't do approaches longer than just a few minutes in my climbing upper layer. I dress really lightly on the top layer for the walk in and then dry off (while not getting chilled) at the base of the climbing. That generally means I bring an extra top layer if the approach is long.
To stay dry on the climb I use a belay sweater/jacket (depending on insulation required by the temps) to let my body heat dry me off and keep me warm while drying out at the belay if I have broken a sweat climbing.
The trick here is to make sure your clothing system will dry out with body heat alone. One wrong layer and the system may not work efficiently. Better yet climb with a light enough and breathable enough set of clothing that you don't wet your body or gear on anything but the hardest leads. It is a tough balancing act.
Light enough...breathable enough?
Four words that are saying a lot! You need to push the definition of both imo.
I switched a few years ago to all Shoeller style clothing. Which if you look at much of what is available today for cutting edge fabrics here in the US is actually a Polartec product. But early on unbelieving on just how far I really needed to go I bought all the gear in a insulated form. I have worn out a set of both over time. And I still love both of them for climbing. For everything but the very coldest weather (below -10C) I find the insulated soft shells to be too much insulation and not breathable enough.
That was then (2010) ...and it may still be true. But last winter at the OR show in Salt Lake City, there were several new fabrics that were getting a buzz. I was lucky enough to get a Neoshell Westcomb Apoc jacket to try out. Previous I had spent years in hard shell Goretex garments and finally abandoned them it for winter climbing. Neoshell was the first of the "modern shells" I have been able to use.
And by most accounts Neoshell is what all the rest of the new fabrics are being judged by if the early reports are accurate.
I am currently testing some of the newest variations on that idea from Polartec. And it would seem that we might actually have more breathable and more water repellant soft shell options available soon. But I'll report what I do find if there is a significant change.
So why too much? Too heavy physically, too warm and not breathable enough.
OK, you ask, "WTF, Dane?" "That is a $400 piece of kit (Gamma MX Hoody) you encouraged me to buy last year and now you are telling me it is rubbish?...too warm?...too heavy?"
This year Arcteryx has changed the material on the Gamma MX Hoody and is offering an alternative to that technology in the Venta MX Hoody. Both are suppose to be more breathable. Patagonia is there as well using Polartec fabrics. Mountain Hardware, Eddie Bauer and Outdoor Reasearch and even Cabella's have joined the game as well.
All with one idea, to stay warm you must stay dry.
Last year I thought the Gamma MX hoody would be the one piece of clothing I would always take on alpine/ice routes. Last winter I didn't use the Gamma MX at all climbing, but did for one day of skiing in the Alps. So, yes it is a big change for me as well. Now I am saying it is too much? Yes....but don't throw it away just yet :)
You need to go back to the idea that "cool muscles work more efficiently".
Mind you it might take you a bit of effort to find out just how "cool" you are willing to work at to make this all work. That might include a trip where you dress too light and freeze your ass off to find out just how "cool" you'll want to be :) I'd suggest you make that trip, a low risk, high energy event. If you blow it bad on the clothing combos at least movement will generally keep you warm. You need to iron out your system in a fairly controlled environment.
The rewards are worth the risk imo. But to be sure, blow these combinations in a big way and cold injury is almost certain or even death will be the end result. I have used the system at a fine edge half a dozen times now and I had significant performance and recovery break through each time. I also look back and thank my lucky stars that there was no "incident" on those climbs that could have easily precipitated a disaster. An unplanned night out in bad weather while cutting it close on gear can be more than just uncomfortable.
The results of 24 unplanned hrs out in 10F temps? And a full year of recovery.
Here are my current thoughts on winter clothing systems. Limit the layers. Yes, limit the layers! The first picture in this post is me climbing early in my career in mostly wool, with temps rapidly going to -40 as the sun went down. It was pretty miserable at the time and to be honest a little scary. I had never been in such temps and that exposed before.
But a couple of things made a big difference. I was mobile, light layers made that possible. I was dry internally because the clothing breathed well and so I stayed warm if I kept moving. Funny now because I realised as I typed this morning that the clothing pictured there (circa 1973) would be a perfect set up for leashless climbing now in very cold temps...say -20C but not at -40C :)
So limit the layers and stay mobile. Easy to do now with modern clothing.
I am using a R1 Hoody inner layer. MEC makes R1 tops and bottoms for something like $60 retail. Or you can buy Patagonia's for $150. Same exact material and in several ways the MEC clothing is better designed imo. Now there is a easy decision for price point. Buy I do like the detailing offered by the R1. I want to be comfortable and the R1s details like a long cut, easily tucked in and off the face zipper make a difference to me. Not a $100 difference mind you as I'll find the R1 on sale before paying retail.
Yes, just the R1 and nothing between it and my skin. Although my lowers are actually Costco longs...almost expedition weight but some brand name called "Paradox". The R1 seems to be just a bit much on my legs and I lose some mobility compared to the Paradox lowers which seem to slide in the outer shell pants I am using easier. Last winter in the Alps on the-20C days I would use two layers of the Paradox longs and lwt soft shell pant. So the system isn't perfect. I'd also add a Merino wool hoody from Sherpa Adventure Gear under my R1 on the really cold days. But even when adding layers for more warmth in the Alps I know the material I was using would breath.
This new technology (again a Polartec concept) Cabela's E.C.W.C.S Thermal Zone® Polartec® Power Dry® might be much better yet than simply dbl layering as I have done in the past to gain warmth.
This technology with a hood would be hard to beat.

It shouldn't be a huge surprise that Mark Twight has his design fingers in the US Military's current cold weather systems,
That depends on the outside temps and the level of aerobic action I expect.
In the past I have used the Eddie Bauer Front Point jacket..it is a combo hard shell and soft shell . Very water resistant (my top was dry in a soaking waterfall that went straight through my pants and filled my boots to the brim) and very breathable. I am highly impressed with the details of this garment and the combo of materials used. A surprising and almost immediate favorite for cold technical climbing. And now discontinued.
But here is where the newest fabrics get interesting. There are now several offerings from Polartec that are soft shell and "hard" shells that might well replace what I thought was a good use of the fabric technology in the EB Front Point.
Patagonia is offering a new Power Shield Pro product, Marmot is offering a Power Shield '02. That is just touching the surface as Mountain Hardware is in the game as is Outdoor Reasearch and Arc'teryx.
We can thank our tax dollars and the US miitary for testing much of this gear and the budgets that enabled Polartec and others to do the research and development.
Arcteryx Atom Lt Hoody....lightly insulated shell with stretch vented sides and under the arms. Again a surprise, water resistant as well but not tested to any extreme yet. Very warm for its weight and thickness but useful in the right temps (cold) for hard climbing because the stretch side panels and insulated body breath so well.
Worth noting that I have now cut one full layer from the previous suggestions from even last year's system. Insulation is used as required in the base layer and in the outer layer. And most manufactures are now making something similar.
Patagonia's Nano series is another example. I use a Nano puff to layer over my Atom light in many cold weather instances. Mtn Hardware has one as well with the stretch side panels . But there is no separate insulation layer short of the belay sweater (like how I am using the Nano Puff) and a actual belay jacket. The real insulation is in layer THREE where the insulation can EASILY be added or just as likely removed to keep you dry and mobile.
For my pants I have been using the Arcteryx Gamma Lt. for three winters now. I did add a set of grommets to use them as a pant gaiter. And no one more surprised than me that a set of generic long johns and a Gamma Lt. would be good enough to keep me warm and toasty from -10C to well above freezing and still breath enough on the "death marches" while toiling and dripping in in sweat. Only disadvantages I see are they aren't very durable and the lower left leg could be more tapered if my crampon "wear" is any indication.

*shown here in combo with the Atom Lt @ -20C in the shade* (lots of other high qulaity jackets in this catagory now)
I use this combo now with a Arcteryx Atom SV and have been happy with it to -20C as well.
Any of these trhee will offer even more warmth if required

As a system that is it...THREE... layers total. And one generally will be in the pack or going in and out of the pack. Only times I have found myself climbing continuously in all three layers on my upper body last winter I was either very tired or more likely it was dark and I was tired.
Staying hydrated and your food intake up as required has not been mentioned. But the fastest way to get frost bite is get dehydrated. Fastest way to get tired and stat moving slowly is not eat enough. You need to manage your clothing system and what you east and drink.
Gloves and boots?
Maintaining your mobility, cutting down on weight by doing so allows you to move faster. You can then use lighter weight boots and gloves and still stay equally as warm or warmer while moving faster with less effort! Add the advantages of leashless tools and the differences of what you can get away with for a glove system while still being comfortable is simply...amazing.
You have to remember it is a SYSTEM. If required I could carry and use both layer TWO pieces together for extra warmth. I'll do another post and describe the boot and glove systems I am using with this clothing combo. Scarpa and La Sportiva for boots and Outdoor Research and Mtn Hardware for gloves cover the brand names here for me currently.
But there are new players here as well, Salewa, Mammut and Arcteryx again. But it is hard to find bad gear these days. Much easier to use the right gear in the wrong place though. I think the newest materials and designs will sort themselves out in the next winter or two and much of this will become common knowledge. Right now it is hard to keep track as there is so much new gear and new applications it is hard to keep track.....I can't.
Bottom line to all this and the field testing? I'm climbing harder and faster with less effort and less clothes and in more comfort than ever before. Huge success for me.
I think you find a similar result.
An after thought..
A long time climbing buddy who on rare occasion reads the blog busted on me for listing all the brand names I use. I search out the best gear for my own use and buy it at retail. No one giving this stuff to me. But that doesn't make it the best gear for your use. I list the manufacturers simply so you can make direct comparison for your own benefit.
