The first cold morning of fall catches almost everyone. You step out at 42°F, shiver, and go back for one more jacket. Twenty minutes later you’re drenched in sweat and then freezing.
The fix is a little counterintuitive: dress so you feel slightly cold when you roll out. Your body will warm up within a mile or two. Use three layers: a thin wicking base, a middle layer you can unzip, and a shell that blocks wind.
At 40 to 44°F, that usually means tights, a long-sleeve base layer, a lined jacket, medium-weight gloves, a headband over your ears, wool socks and shoe covers. At 45 to 49°F, I swap the lined jacket for a light wind jacket, drop to thin gloves and wear just a thin ear band.
Cold weather cycling chart by temperature (°F)
| Temp | Top | Legs | Hands | Head and neck | Feet |
|---|---|---|---|---|---|
| 60-69°F (15-21°C) | Jersey with arm warmers, or a thin long sleeve; packable vest | Shorts; knee warmers optional | Thin gloves, optional | Nothing | Regular socks |
| 50-59°F (10-15°C) | Base layer, long-sleeve jersey, vest or packable jacket | Tights, or shorts with leg warmers | Thin full-finger gloves | Ear band, optional | Wool socks; toe covers optional |
| 40-49°F (4-9°C) | Base layer, long-sleeve jersey; lined jacket at 40-44°F, wind jacket at 45°F and up | Tights or leg warmers | Medium full-finger gloves at 40-44°F; thin at 45°F and up | Thin headband or thin cap over ears; thin neck gaiter | Wool socks, shoe covers |
| 32-39°F (0-4°C) | Base layer, thermal jersey, insulated vest or jacket | Thermal tights | Heavy gloves | Thick headband over ears; neck warmer | Shoe covers or winter shoes, wool socks, toe warmers |
| Below 32°F (below 0°C) | Heavy base layer, jersey, heavy lined jacket | Heavyweight or winter bib tights | Lobster-style gloves or mittens | Lined skullcap under the helmet; neck warmer; balaclava from about 25°F down | Winter shoes or covers, wool socks, toe warmers; plastic bag from about 25°F down |
The bottom row assumes you already own proper winter kit. I cover where to call it off in “How cold is too cold?” below.
Treat the chart as a starting point, then move a row up or down. I step one row colder (meaning warmer clothes) when it’s cloudy or windy. I step one row warmer when it’s sunny and calm, or when the day will warm up while I’m out.
Wind makes the step concrete. Say it’s 40°F with a 15 mph wind. That feels closer to 32°F, so dress from the 32-39°F row. Check the “feels like” number and wind direction before you leave. Rain changes the answer, too: wet 45°F is a different ride from dry 45°F.
Effort and terrain matter as much as the number. A hard 90-minute ride makes plenty of heat, so dress lighter and expect to unzip. An easy café ride with long stops makes little, so dress warmer and carry a spare layer. Where you start counts too. Begin with a climb and you’ll be warm in minutes. Begin on a flat road or a long descent and the chill hangs around much longer.
Build the layers
Base layer
Keep it thin, snug and quick to dry. A bulky “winter” base against your skin holds sweat and chills you the moment you stop pedaling. Put the warmth in the layers above it.
Fabric is the other choice. Merino stays warm when it’s damp and doesn’t get smelly, but it costs more and wears out faster. Synthetic dries faster and is cheaper, though it picks up odor quickly. For a long ride I’d pick merino. For a short commute, synthetic does the job for less.
Middle layer
Think of it as your thermostat, so buy one with a full-length zipper. Open it on climbs, close it on descents. A regular jersey under a thermal one works well because the jersey wicks and you can vent the outer layer.
Shell
I like a softshell with a windproof front and a breathable back for most cold days. In steady rain a waterproof hardshell makes sense, but open its vents early. If you’re shopping, our roundup of Gore-Tex jackets for rough weather is a place to start.
Skip the big puffy jacket. It restricts your arms, makes you sweat, and you end up colder. Several thin layers beat one thick one.
Legs
As it nears freezing, choose tights over leg warmers. Bibs and shorts leave a strip of upper thigh bare, and it gets cold fast. Covered knees are more comfortable and kinder to your joints.
Winter kit adds up, so borrow where you can. Running tights work fine over your regular bibs. Watch the seat, though: loose tights can sag over padded bibs and snag on the saddle when you remount.
Hands, feet and head
These are the first places that hurt, so they set your real comfort level.
Hands
Glove weight should climb with the chart. Thin full-finger gloves work around 45°F, medium at 40°F and heavy at 35°F. Below freezing, switch to lobster gloves or mittens. They keep your fingers together for warmth but still let you brake and shift.
One catch: lobster gloves can be too bulky for electronic shifting buttons. Try them on your bike before a cold ride. On long winter days, carry a second, lighter pair for when you warm up.
Gloves are usually the first upgrade. For specific pairs, see our winter glove picks.
Feet
Toes lose first. Shoe covers help most, though they’re a hassle to pull on, so leave yourself a few extra minutes. Wool socks come next. Ski socks that reach the calf are a cheap upgrade, and our cycling socks roundup covers cycling-specific options. For cover choices, see our winter shoe cover guide.
Here’s the catch most people miss. Thick socks in a tight shoe squeeze your toes and cut circulation, so your feet end up colder than they’d be in thin socks. If you’re stacking wool socks and toe warmers, go up a half size in shoes or covers.
Add charcoal toe warmers from about 35°F. Stick them on the outside of your toes, under the shoe cover. Sweat inside the shoe can shut them down. At 25°F and below, put a plastic bag between sock and shoe to hold in heat.
Toes still going numb? Our guide to numb feet while cycling covers the usual causes.
Head and neck
Cover your ears and let the top of your head vent. What fits under a helmet changes with the temperature:
- 40s: a thin headband or thin ear-covering cap.
- 32-39°F: a thicker headband over your ears, plus a neck warmer.
- 25-31°F: a lined skullcap, which is thin enough to wear under the helmet.
- Below 25°F: a balaclava. It’s too hot before that.
Most plain cycling caps are too thin for winter, and bulky knit hats won’t fit under a helmet. Wraparound glasses cut the wind. Cold makes your eyes water, so wear them even on gray days.
Commuters and e-bike riders
On a regular bike
A commuter at 10 to 12 mph makes less heat than a road rider but also meets less wind, and stoplights give you a break from the chill. Dress lighter on your torso. Keep full protection for your hands, feet and ears, because they get cold no matter how easy the pace is.
The bigger problem is the desk at the other end. Wear a wicking base layer and pack a dry spare. A small frame or bar bag holds a vest, spare gloves and a shell. Reflective panels on a jacket help drivers spot you on dark mornings.
On an e-bike
The motor does some of the work, so you make less heat. Class 1 and 2 e-bikes also assist up to 20 mph, and at 18 to 20 mph with low effort the wind chill is real. Step one row colder than the thermometer says. A windproof outer layer pays off more than extra fleece.
Cold hits the battery too. Near freezing, plan on roughly a quarter to a third less range, and more on a very cold day. Keep the battery indoors until you roll out, since a warm battery holds its range better in the first miles. Trim your route to match, or bring the charger on a long ride. Battery range in the cold gets its own guide: cold weather and e-bike batteries.
How cold is too cold?
There’s no single cutoff. It depends on your gear, the wind and how long you’ll be out. Here’s how I frame it. The chart works for anyone down to 32°F. The 20-31°F range is for riders who already own the kit. Below 20°F, keep rides short and close to home, or take the trainer. Skip ice at any temperature.
Fingers are a good gauge. In a decent winter glove, they should warm up within about 15 minutes. If yours don’t, head home. Cold, wet hands can go numb and even lead to frostbite.
Long rides carry another risk: stopping. A sweaty rider who stops at a café can chill quickly. Below about 40°F, I carry a dry base layer so I can change there instead of freezing 30 miles from home.
Quick answers
What to wear cycling in 40 degrees?
The outfit in the intro is your baseline. Two things change it. If it’s windy, dress from the 32-39°F row: thermal jersey, heavier gloves. If it’s wet, wear a waterproof shell with the vents open early, and put the shoe covers on, since wet feet go cold first.
What to wear cycling at 50 degrees, or 10-15°C?
Wear a base layer, a long-sleeve jersey and thin full-finger gloves. At 50°F, go with tights and add a wind vest and an ear band if it dips. At 58°F, switch to shorts with leg warmers and leave the vest in your pocket. Twelve degrees Celsius is about 54°F, and 15°C is 59°F, so the same row covers all of it.
Do I need special winter cycling clothing?
Not all at once. Plenty of gear carries over from running and skiing. If you’re buying in order, start with gloves, then tights, then shoe covers, since hands, legs and feet are what hurt first.
