Fabric that’s comfortable all the way from kinda cool to slightly warm!

“keeping the wearer comfortably warm in temperatures as low as 11°C. Yet if the fabric is flipped inside-out, it could emit as much radiation as bare skin – keeping the wearer cool in temperatures as high as 24°C.”

For years I had trouble running into the winter. I eventually figured out that I’d simply had the wrong idea about how to do it. I’d imagined that if I just continued running through the fall, I’d gradually ease myself into winter running. That never worked—because there are plenty of warm days (or at least warm hours) through early fall, and then in middle or late fall there is (identifiable only in retrospect) a last warm day, and then it’s cold nearly every day until late March or early April. So even if I ran through fall, if I chose to get in my runs during the warm hours, I wouldn’t actually develop tolerance for the cold, the wardrobe for handling it, or the skill at picking the right garments.

A couple of years ago I failed to run through the fall, and then decided to develop a winter running habit anyway. I bought a few pieces of cold-weather gear—plenty, because I was generally only running once or twice a week.

I started with the sweats I wear to teach taiji, and then I added two pairs of tights—one sort of classic running tights, and then another pair of fleece tights, that ought to be good down to colder than I’m every likely to try to run in.

For tops I generally wore a regular sweatshirt over a regular cotton t-shirt. Then I got some short- and long- sleeved merino t-shirts, which are vastly better as a base layer. I also dug out a capilene half-zip top that my dad gave me a few years ago, which was just the thing when it got a little colder.

I also got a washable merino knit hat in high-viz yellow, and two different pairs of gloves in high-viz yellow—first a pair from the dollar store, which were not nearly warm enough, then a pair from Amazon that I think was marketed to people directing traffic, that were dramatically more high-viz, but still not quite warm enough.

Now that I’m in my third year of winter running—and now that I’m running more times per week—I’ve added a few more pieces of winter running garb.

I bought a third pair of high-viz gloves, these from Illinois Glove company, which are finally warm enough, and almost as high-viz as the previous pair.

Last winter I picked up a pair of Janji Mercury Track Pants, which are wonderful. Size medium fits me perfectly, they’re warm enough down to well below freezing (and I rarely run when it’s below freezing, because of slipping hazards). I liked them so much I picked up a second pair last year, and just now got a third pair (because a couple of weeks ago I wanted to go for a run and both of the first two were already in the laundry).

Last year I added another quarter-zip pullover in some high-tech fabric that I picked up cheap at Amazon, and just now today another fancy Patagonia capilene base-layer top that I can wear either by itself, over one of my merino T-shirts, or under a wind-proof or water-proof layer.

I’ve gone running five or six times in the last couple of weeks, at temperatures ranging from right at freezing up to maybe 50℉, and so far I’ve managed to nail it each time as far as matching the warmth of the clothing to the conditions outside.

I have one more piece of running gear that I’ve ordered, but that hasn’t arrived: a headlight. Normally I just don’t run when it’s dark. (Since I don’t work a regular job, I have the freedom to choose to run only during daylight.) But a couple of times in the last few weeks, I wanted to go for a run that would start in the daylight, but might not finish until after dark. I figured that a headlight might be very useful as a just-in-case piece of safety equipment, even if I didn’t plan on doing much nighttime running. I ordered this Spriak Wide-Beam headlight, which seems like it would serve my purpose as emergency safety gear. If I end up running in the dark on purpose, rather than by accident, I’ll be tempted to step up to this Petzl Headlamp that offers 3x to 15x the battery life, and what looks like a rather better system for fitting the whole thing on your head, but costs 10 times as much ($200 vs. $20).

If circumstances develop in any sort of interesting direction—if it turns out that the gear I’ve got doesn’t cut it for this or that sort of conditions, or if I decide that I need some other bit of fancy running kit, or if one of the things I’ve got turns out to be even more suitable than I’ve already described, I’ll go ahead to write another post.

If you’ve got great winter running gear, I’d be very interested to hear about it! Comment below or reach out on social media or by email (see my contact page for ways to connect to me).

Jackie and I went out for a walk this morning, as we do. The double-digit negative windchill seemed to offer a bit in the way of bragging rights, even if it wasn’t nearly as cold as a year ago.

I’ve got a bit more in the way of clothing choices this year, having bought a bunch of cold weather gear for winter running, but I didn’t use much of the new stuff.

I wore my Alaska pipeline coat, of course. Under that I wore my Dale of Norway sweater that Barbara bought on her last trip to Antarctica. Under that I wore a silk mock-T base layer. For my lower body I wore my flannel-lined jeans, which were just the right weight by themselves. (I’ve got a pair of fleece-lined khakis a size larger, big enough to wear tights or something under, for when it’s really, really cold, but I didn’t need them today.) I wore silk sock liners under my usual wool/silk-blend socks, under my new waterproof Lems boulder boots. (I’m very pleased with these boots so far. All the minimal/barefoot features I want, waterproof, and warm enough for the bitter cold.)

The one imperfect thing about the Alaska pipeline coat is that the hood is hugely oversized (I assume so that it can go over a hardhat) and tends to slump down over my face, obstructing my vision. So to keep my head warm I wore the Khyber pass hat that Jackie made me. (If you remember the war in Afghanistan, the Northern Alliance forces wore the same sort of hat. Very versatile—roll it up and it covers the top of your head to keep the sun off. Roll it down and you’ve got a thick wool hat you can pull down over your ears.)

All of that, except the bolder boots, was pretty much what I was wearing a year ago in the picture above, but this year I had one novel item: I wore a buff over my neck and the lower half of my face. It’s just a thin layer of microfiber, but over my beard it was dramatically warmer than just the uncovered beard. I’ve had buffs for years, but I mostly wear them in hot weather (to keep the sun off my neck), so I think of them as cooling rather than warming. It was amazing to find how much of a difference it made just to put a layer over my beard.

Me in winter running gear

Every year I try and fail to establish a winter running habit. This year I managed, and learned a bit about why I usually fail.

In my imagination, the key has always been to keep running through the fall. As it gradually gets chilly and then cold I’ll gradually adapt.

That never works.

The main reason it never works is that seasons don’t work like that. One gets frequent warm days in early fall, then infrequent warm days in late fall, and then at some point—identifiable only in retrospect—there’s a last warm day, which is then followed by months of winter weather.

But it’s even worse than that, perhaps especially so for people like me who don’t have a regular job. Since I have pretty complete control over my schedule, I’m able to get out for my runs whenever the weather is optimal. In the summer I can run in the morning or evening when it’s not too hot. In the fall I can gradually shift my runs toward mid-afternoon when it’s not too cold.

The upshot of that is that I’m never confronted by gradually cooler temperatures when I go out for my runs. Rather, I get to run when the conditions are perfect right up to the last day of perfect conditions. Of course, there are days when conditions are imperfect all day, but I can adapt by just shifting my run to the next day or the day after—a strategy which works fine right up until late fall, when all of a sudden conditions are imperfect every day.

This fall as usual I failed to establish a running habit. I ran into mid-September, and then quit running for two months. But somehow I managed to get started again in mid-November, and proceeded to get in 24 runs from then until April Fools Day. Why this year and not other years? The answer comes out of looking at the reasons why I don’t run in the winter: Cold, dark, and ice.

For ice I have to chalk this success up largely to luck. We had an ordinary amount of snow this year, but the size of each snowstorm and the timing of warm and sunny bits after snowstorms meant that it was rarely more than a week or so before the sidewalks were clear enough that I could get out for a run. (In my running log I only spot five weeks with no running, and only one spot where two of those weeks are consecutive.)

For dark the credit goes back to my not having a regular job. There’s no boss expecting me to spend my daylight hours sitting at a desk. I can run whenever I want.

So it comes down largely to cold.

I have always been of the opinion that dealing with cold is just a matter of having the right gear, and I had some of it—a pair of very warm tights, a half-zip capilene top, some sweat pants, some mock-Ts, some sweatshirts, a silk baselayer, and a bright-red buff with reflecty bits.

To this I gradually added a machine-washable merino wool hat in high-viz yellow, a pair of high-viz yellow gloves, and a pair of lighter-weight tights suitable for wearing in moderate cold.

That little burst of consumerism turned out to be highly effective. First, it meant that I had the right clothes for the conditions, from pretty cold up to just barely too cold for shorts and a t-shirt. Second, because I wanted to give my new gear a try, I got out for at least three (probably more like six) runs that I’d otherwise have skipped, just because I wanted to wear my new tights or my new hat.

And so, for the first time since 2004 I have come into spring with a running base that prepares me for serious training right off the bat. I can comfortably run 10k, so I could compete in any 5k or 10k race this spring. I could easily be in shape for the 7.1-mile Lake Mingo Trail Race in early June. I’m probably within striking distance of being in shape for a half-marathon (although not the Illinois Marathon half-marathon in less than three weeks).

Mainly though, I’m in shape to just keep running on through the spring and summer. And maybe, just maybe, next fall.

Behold a gallery of running-related images from the winter, most of which were shared to my twitter feed sometime along the way:

It was on my first trip to England that I came to understand that what we think of as formal wear, business attire, and sports clothing was originally designed to be the most comfortable possible clothing for the circumstances. The circumstances in this case being the climate, technology, and infrastructure of England in the eighteenth and nineteenth century.

Without central heat interiors were going to be chilly, but even if you were quite frugal with your wood or coal they would not have to be really cold.

Given those indoor circumstances, and given that you had to make do with wool, silk, linen, and cotton (because there were no synthetic fibers), you would quite naturally end up with just the sort of garments that we now think of as being part of formal wear—wool coats and vests, silk bands to wrap around your neck, and so on. Sport clothing, of course, was for the sort of sports the English aristocracy engaged in: riding and shooting. Tweed and leather were very practical.

It seems obvious now, but it was something of a revelation to me. When I was younger, I always thought of that sort of clothing as being uncomfortable.

Partially that’s because such clothing is only really comfortable if it really fits. You don’t need a bespoke suit for it to fit correctly; even today good men’s clothing is routinely altered to fit. But clothing purchased for a child will never fit for long (and often never fit at all, because the child knows neither how the garment is supposed to fit nor how to articulate any issues discovered during the fitting).

Perhaps more important, such clothing is only comfortable in the sort of very cool environment for which it was originally designed. If your interior temperatures are around 60°F, you will be more comfortable in a wool coat over a wool vest than you would be in shirtsleeves. At 70°F it will be the other way around.

My attitudes toward such things has also been influenced by Jackie’s work with fiber. In my youth, my experience with wool was that it was scratchy, uncomfortable stuff (totally aside from it being made into garments that didn’t fit and were wrong for the climate). Now I’ve learned about the many different kinds of wool—starting with merino, of course, but by no means ending there—that are not scratchy. Now I have wonderful vests and sweaters, made to fit, from premium materials.

Of course, the top layers are really the last thing to think about. Comfortable clothing begins with the base layer. There again, my experiences as a child turned me against a whole very useful category: long underwear. Any clothing that you’re going to put another layer of clothing on top of needs to fit exactly right. An outer layer that’s too loose can be tolerated. But a too-loose under layer is going to get bunched up and shifted away from where it needs to be: Intolerable.

The ill-fitting hand-me-down long underwear I got as a child turned me against a whole category of garments that doubtless have an important role to play in comfortable dressing. I’m only now, more than two decades after returning to the Midwest, beginning to accumulate items for an appropriate cold-weather base layer. (I’ve made do up to now by having a wide range of top-layer options: spring jackets, fall jackets, winter coats, parkas, my Alaska pipeline coat.)

As a young man, I think I’d have been perfectly happy to wear nothing but shorts and t-shirts, and simply crank up the heat to make up the difference. My attitude has changed. If I had the money, I’d be very pleased to get and wear wool coats and vests, silk cravats, smoking jackets, and the like. Not because of the fashion statement they’d make (which would be a rather silly statement, however much I’ve come to appreciate a fine tweed), but because they’d be very comfortable.
