What should I wear today?

From our weather station

Start with our What to Wear tool. Tell it who’s going out, what they’ll be doing and for how long, and it suggests a layered outfit for right now in Lethbridge, using live readings from Gary’s West Lethbridge weather station, including wind chill. It also covers dressing kids and babies, footwear on ice and chinook days.

This section goes deeper: why each layer and fabric works, what to buy and what to skip, and how to stay warm, dry and safe on your feet and in the sun. Check the forecast page for the day’s high, low and wind.

Dressing for our swings

Southern Alberta weather changes fast. Chinook winds can raise the temperature sharply in a few hours in winter, and the cold can come back just as quickly when the chinook ends. Summer can bring a cold morning, a hot afternoon and a thunderstorm on the same day. Strong wind is common all year.

So the goal isn’t one perfect coat. It’s a set of pieces you can add and take off as the day changes:

  • Dress for the coldest part of your day, not the temperature when you leave the house.
  • Carry the layer you took off. A jacket in the vehicle or your bag is worth more than a warmer one at home.
  • Plan for wind. A windproof outer layer often matters more here than a thicker sweater.
  • Plan for wet. Rain, wet snow and sweat all steal heat.

For how chinooks work and how to dress for them, see Chinook days on the What to Wear page.

The layering system

Health Canada’s cold-weather advice is to dress in layers with a wind-resistant outer layer, and to take layers off before you start sweating or add one if you get cold. The basic three layers are explained on the What to Wear page’s How layering works. In short:

👕

Base layer

Next to the skin. Moves sweat away so you stay dry. See the warmest base layers.

🧥

Mid layer

Traps warm air. Fleece, a wool sweater, or an insulated vest or jacket. Add or remove more than one as needed.

🧥

Outer layer

Blocks wind, rain and snow. A shell, or an insulated parka for real cold.

What it means for you: several thin layers beat one thick one. They trap more warm air, and you can fine-tune them through the day. If you’re going to work hard (shovelling, hiking, cycling), start a little cool and open zips before you sweat.

The three-layer clothing systemA cross-section from skin to outside. The base layer moves sweat away from the skin, the mid layer traps warm air, and the outer shell blocks wind, rain and snow. Good base fabrics are wool or merino, polyester, polypropylene, or silk for mild cold. Mid layers are fleece, a wool sweater, or an insulated vest or jacket. The shell is a windproof shell, rain jacket or insulated parka.

Three layers, three jobs: move sweat out, hold warm air in, keep wind and wet out. Take a layer off before you sweat; add one when the wind picks up. Source: Health Canada, Extreme cold (dress in layers with a wind-resistant outer layer; synthetic and wool fabrics insulate better).

Fabrics that work

Health Canada says synthetic and wool fabrics provide better insulation, and that some synthetics are designed to pull perspiration away from the body.

FabricGood atWatch for
Wool (including fine merino)Warm even when damp, comfortable over a wide range of temperatures, resists odour, so it can be worn for days.Slower to dry than synthetics, less durable in thin weights, can itch (fine merino much less so). Wash gently.
Polyester (including fleece)Holds very little water, dries quickly, durable, warm for its weight.Can hold odour. Fleece lets wind straight through unless it has a wind-blocking layer. Melts near sparks and flame.
PolypropyleneAbsorbs almost no water and moves sweat away fast. A long-time base-layer fabric.Holds odour; can be damaged by a hot dryer.
NylonTough and wind-resistant; common in shells and pants.Not warm on its own.
Wool and synthetic blendsMix the warmth and odour resistance of wool with the speed and strength of synthetics.Performance depends on the mix.
SilkA thin, light base layer for mild cold.Not durable; not as warm when wet.

Around the campfire, synthetic fabrics can melt from a spark or flame. Wool is the safer choice near a fire or wood stove.

Down or synthetic insulation

Insulated jackets, vests and parkas are filled with either down (the soft under-feathers of ducks or geese) or synthetic fibre.

DownSynthetic

LifespanLong, if cared forSlowly loses loft with compression and washing

Down is often described by “fill power”: higher numbers mean the down is fluffier and gives more warmth for its weight. But the amount of fill and the design matter just as much, so compare jackets in person.

  • Store insulated garments loose, not crushed in a stuff sack, so they keep their loft.
  • Wash according to the label. Down needs a gentle wash and a long, low-heat dry to fluff back up.

Shells: wind and rain

  • Windproof shell. A light, tightly woven jacket that stops wind. In Lethbridge this may be the single most useful piece of clothing you own. Over a fleece it can turn a raw, windy day into a comfortable one.
  • Waterproof-breathable shell. Keeps rain and wet snow out while letting some sweat vapour escape. Look for taped seams and a hood that moves with your head. No shell breathes well enough to keep you dry if you work hard in it, so open the vents and zips.
  • Soft shell. Stretchy, wind-resistant and water-resistant (not waterproof). Comfortable for active days in dry cold.
  • Insulated parka. Shell and insulation in one. Warmest for standing around in real cold, but too warm for hard work.
  • Rain pants or wind pants are as important as the jacket on a wet or windy day.

What it means for you: waterproof shells lose their water-repellency over time. When rain stops beading and starts soaking into the outer fabric, wash the shell as the label says and renew the water-repellent finish.

Why cotton and denim fail

Gary’s rule is ABC: Anything But Cotton. He considers cotton and denim extremely cold materials. His story is on our Camp gear page.

Cotton soaks up water from rain, snow or sweat, holds it against your skin and dries slowly. Water takes heat away from the body much faster than air does. The Canada Safety Council says wet clothing is a common cause of hypothermia, and that hypothermia can happen at temperatures under 10°C. That’s an ordinary summer night here. Health Canada’s advice is to change into dry clothing as soon as possible if you get wet.

  • Jeans are the worst offender. Heavy, slow to dry, and cold and stiff once wet. Wear wool or synthetic pants, or put wind or rain pants over them.
  • Cotton T-shirts and hoodies make poor base layers for anything active. Save them for the drive home.
  • Cotton socks lead to cold, wet feet and blisters. See Socks.
  • Cotton is fine for hot, dry summer days, where staying cool matters more than staying warm.

The What to Wear page explains why cotton fails in more detail.

The warmest base layers

A good base layer, a long-sleeved “warm tee” and long underwear, does more for comfort in our winters than almost anything else. What makes one warmer than another:

FeatureWhat to look for
FabricWool (merino is soft enough for most people), polyester, polypropylene or a wool-synthetic blend. Never cotton.
WeightOften sold as lightweight, midweight and heavyweight. Lightweight for active days and mild cold; midweight for most winter days; heavyweight for standing around in real cold.
KnitA brushed or grid-fleece inside traps more air and feels warmer. Smooth knits dry faster and layer better.
FitClose to the skin but not tight. A base layer can only move sweat if it touches you.
CoverageLong sleeves, a longer back, thumb loops, and a zip or high neck for venting and warmth.

What it means for you: for most people in a Lethbridge winter, a midweight wool or synthetic top and bottom covers the most days. Add a lightweight set for spring and fall, and for hiking and cycling. A wool or synthetic layer is also the best thing to sleep in at camp.

Head, hands and neck

  • A toque or warm hat that covers the ears. It’s the easiest layer to add and remove.
  • Mittens are warmer than gloves, because fingers kept together share warmth. Thin liner gloves under mittens let you do fiddly jobs without bare skin.
  • A neck warmer or face covering on windy days. Health Canada suggests covering your nose in the cold. For children, Alberta Health Services recommends neck warmers rather than scarves, which can catch; see Dressing kids and babies.
  • Carry spares. Wet gloves and hats lose most of their warmth. A spare dry pair in a pocket or the vehicle makes a big difference.
Kids’ corner

Why do layers keep you warm? Clothes don’t make heat. Your body does. Clothes trap still air around you, and still air is very good at holding heat in. Several thin layers trap several layers of air.

Wonder: why does a windy day feel so much colder than a calm day at the same temperature?

Try this: on a cold day, put on a fleece and stand in the wind for a minute. Now put a rain jacket over it. Which feels warmer, and why?

Heated clothing and battery safety

Heated vests, jackets, gloves, socks and insoles, usually run from a rechargeable lithium-ion battery pack or a USB power bank, can help people who feel the cold or stand still outdoors for long periods. They also bring fire and burn risks, especially for anyone who can’t feel heat well.

Choosing

  • Look for a recognized Canadian certification mark on chargers, such as CSA, cUL or cETL. Health Canada says chargers without these marks may not meet electrical safety standards.
  • Use the charger that came with the product. If you need a replacement, Health Canada advises buying from a trusted source and matching the voltage and current.
  • Check for recalls on the Government of Canada’s Recalls and safety alerts website. Heated gloves with rechargeable batteries have been recalled in the past because the batteries could overheat while charging.

Using and charging

  • Charge indoors at room temperature, away from soft surfaces such as a couch or bed that can trap heat, and away from exit doors. Health Canada says not to charge lithium-ion batteries in below-zero temperatures, so don’t charge them in a cold vehicle or garage.
  • Don’t charge longer than recommended, and unplug when full.
  • Don’t leave batteries in the sun or in a hot or cold car. Cold also drains them much faster; keep a spare in an inside pocket.
  • Stop using any battery that is swollen, dented or has a torn wrapper, and any garment with damaged wires, scorch marks or hot spots.
  • Start on low and check your skin often. Take extra care with children and older adults. Don’t use heated clothing on babies or toddlers, or on anyone who can’t tell you it’s too hot or take it off. If you have diabetes, poor circulation or reduced feeling, ask your health care provider before using heated socks, insoles or gloves: Alberta Health Services’ foot-care advice is not to use hot water bottles or heating pads on your feet.
  • Dispose of batteries properly. Health Canada says they are hazardous waste and shouldn’t go in household garbage. Check with the City for drop-off options.

Always have a non-electric backup. A battery can die halfway through a cold walk or a long night. Dress so you’d still be safe without the heat. For heated sleeping gear at camp, see Heated and USB options.

Clothes in the vehicle

If you break down on a highway in a ground blizzard, you’ll be wearing whatever is in the vehicle. Gary keeps his truck well stocked. In his words, it’s “a complete setup: emergency kits, extra clothing, cookware, stoves, you name it.”

  • A warm jacket, toque, mittens and a neck warmer for each person who usually rides along.
  • Warm, waterproof boots and wool socks. See Footwear.
  • A wool blanket or sleeping bag.
  • Rain gear and a sun hat in summer.
