Mid layers

Why use a layering system?

Canadian weather can quickly shift with cold mornings, warm afternoons, wind gust, or powdery snow. A layering system keeps you comfortable whether you’re skiing, snowboarding, hiking, snowshoeing or enjoying outdoor après-ski festivities. Each layer has a role: the base layer manages moisture, the mid layer traps heat without trapping moisture, and the outer shell shields you from wind and precipitation. Together, they let you adapt to changing temperatures and activity levels without overheating or getting chilled by removing or adding layers.

What is a mid layer?

A mid layer is the garment you wear between your base layer and your outer shell. It can take many forms, including fleece jackets or vests, long-sleeve shirts, hoodies, and sweaters. Depending on conditions, it can be worn on its own or added under a jacket as part of a layering system. Its job is to hold warmth close to your body while letting moisture escape.

What materials are used in mid layers?

Down Insulation

Light, ultra-warm, and very compressible—great for dry, cold days and packing small. Less effective when wet and better for lower-intensity activities or breaks.

Synthetic Insulation

Breathable, quick-drying, and warm even when damp. A solid choice for active sports, such as skiing, snowboarding, or hiking in variable weather.

Fleece

Soft, breathable, and affordable. Retains warmth even if damp, but not very compressible and less wind resistant.

Merino Wool
Naturally breathable, moisture-wicking, and odour-resistant. Soft to wear, not scratchy like other wools.

Which materials and garments are the best choice for my activity?

There are no hard and fast rules for choosing a mid layer. Comfort depends on how warm or cold you tend to run, the day’s weather, the activity’s intensity, and your preferences. That said, here are some basic recommendations.

Alpine Skiing and Snowboarding

Many skiers and riders wear an insulated mid layer (synthetic or down) under a shell all day, especially on cold or windy lifts. On milder days, a fleece or light puffy can work as an outer layer.

High-Intensity Activities

When you’re going hard in outdoor sports, such as alpine touring, cross-country skiing, and snowshoeing, a base layer and breathable shell are often enough. To stay comfortable, keep a warm, packable down mid layer ready for rest stops, transitions, descents, or sudden drops in temperature. Having a warm mid layer also adds a measure of safety since it will help you stay warm in case of injury.

Everyday Wear and Travel

A down or synthetic mid layer adds warmth without bulk and works well on its own in cool, dry conditions or layered under a shell when it’s wet or windy.
