You go to ride on the day you have

Only an idiot would go for a bike ride in November rain mixing with snow, with a temperature barely above freezing. So let me tell you what I wore...

Cold weather riding depends on moisture management even in dry conditions. Your body puts it out constantly. Exertion makes you sweat even if the air is cold.

Any outdoor adventurer is advised to wear fabrics that are "warm when wet and fast drying." These fabrics are not as warm when wet as they are when dry. If you expect to get wet, add layers to slow the rate of heat loss through the wet fabric.

Quick review: you lose heat through conduction, convection, evaporation, and radiation. Conduction occurs when you put your warm self in contact with a cold substance -- water, for instance. Or ice. Or cold rocks. Convection is just a fancy word for the wind blowing across you. It could be an annoying cold draft inside your house or a winter gale on a treeless mountain. Or it could be the constant self-created breeze as you pedal through the chilly atmosphere. Evaporation is how your sweat keeps you cool in summer heat, or tries to. It's the body's response to rising internal temperature, so you will perspire when you exert even when you wish you wouldn't. And then radiation is just your precious heat beaming away from you in all directions.

Cold weather cycling is just about the hardest activity to dress for. You can block the wind or mitigate its effect with either shell clothing or more insulating fuzzy layers without a shell. I used to use the second option until I got a particular yellow Sugoi wind jacket that hit the perfect balance of wind blocking and breathability. I wanted something that gave better visibility than my former dark layers, without the full panic mode of hi-viz please-don't-kill-me-yellow. When it was brand new it even repelled water pretty well, but that always fails early in a garment's life. I have never been able to reestablish it in any shell garment, with wash-in or spray-on treatments. But it cuts the wind whether it's wet or not.

For the legs, I used to wear various layering combinations of wool tights with long underwear under and/or wool leg warmers over, with bike shorts as the innermost layer. For sub-freezing temperatures, I would add wind briefs over the shorts. Then I got Sport Hill 3SP fabric XC Pants. They are incredibly effective at blocking wind, while remaining completely breathable. Made of polypropylene, they transport moisture to the surface, where it forms droplets or frost that can be brushed away. So for most cool to mild cold conditions it's bike shorts and 3SP pants. But actual rain adds a factor. Under those conditions I need to turn the outfit into a wetsuit. So I put my lightest polyester riding tights under them.

For the shirt layers, a standard crew neck poly shirt is first.

Followed by a classic wool jersey.

And then a heavyweight (actually pretty light, just thicker) old Craft zip-t

Because the core is critical, I always put a wind vest in the system. Again, Craft. This one with a solid rather than mesh back. The chest pocket is just big enough for my phone.

I led with the shell jacket. No need to repeat. In case I had to stop for a mechanical or other unscheduled delay, I stuffed a Craft warmup jacket with Gore Windstopper panels on the front of it into the rack pack.

Feet just hang down there in the cold wind. For cool rides, I put cut off ends of bread bags over the front of my socks for toe warmers. When the temperature drops to freezing and below, I go to liner socks with full bread bags over them.

If the air is cold and dry, another set of bags goes over the medium-weight wool socks I put over the liners. For wet weather, I put the bags on the outside, over the shoes. Wet shoes take days to dry out. I don't want to ride in wet shoes or go days without a ride while I wait for them to dry. The bags provide better coverage than any of the official cycling shoe covers I've ever had, and I collect tons of bread bags from buying my weekly groceries.

For the challenge of near-freezing wetness I wore these North Face Apex gloves. They are the most wind-blocking gloves I have owned (so far). Not my absolute favorites, because the gauntlet is too tight to pull easily over the jacket sleeve, but top-level protection from cold wind once you've wrestled them into place.

Under the helmet: this old liner from when our shop sold hockey stuff. It's just a simple beanie that pairs nicely with the Cat Ears ear covers on the helmet itself. For really cold rides I use a thin poly balaclava, but usually do not have it pulled down to cover my face. For whatever reason, I have not had problems with frozen face. Maybe it's because I try to do more hiking and skiing than riding when winter is in full force.

Helmet gets taped up over the front vents, leaving the rear vents clear. The headlamp serves as dashboard lighting if I ride at night.

The final accessory is the windshield wiper, a scrap of bandanna for wiping my glasses.

The cold and wet bike: a fixed gear with full fenders. It will keep you warm.

After all that preparation to endure character-building suffering, the rain let up enough that I only had a bit of a chill on the front of my arms once the fabric was thoroughly wet. Seriously nothing debilitating. I looked forward to riding the next day in a similarly wet forecast, but warmer, so without the snowflakes mixing in.
