Choose the right base layer

Learn how to choose the right base layer based on your activity, temperature and body. Find what suits you best, whether you get cold easily, stay active or spend time in cold or mild conditions.

Why is a good base layer important?

When you spend time outdoors, regardless of activity, the right base layer is essential for comfort and performance. A wool base layer with good insulation and effective moisture management keeps you dry and warm, even when you sweat. Since moisture cools the body quickly, it’s important to choose materials that move moisture away from the skin. Here are our best tips to help you choose the right base layer for your needs and activities.

Step 1: Choose the right material

Why choose a wool base layer?

Wool is superior when it comes to keeping you dry and warm. It effectively wicks away moisture, insulates heat, and can absorb a large amount of moisture without feeling wet. Unlike synthetic and cotton materials, wool continues to keep you warm even when damp, making it a reliable choice for both activity and rest.

Step 2: Body temperature

Do you get cold easily or tend to feel warm?

Your body temperature affects which material and thickness will suit you best.

Ullfrotté 200

Do you get cold easily?

For those who tend to feel cold, a base layer with good insulation is essential. Ullfrotté 200 is a classic base layer that traps body heat thanks to its airy structure. Worn closest to the skin for best effect.

Woolpower LITE

Do you tend to feel warm quickly?

For those who easily get warm, a base layer with efficient moisture and heat regulation is essential. Woolpower LITE is a thin, rib-knitted base layer that fits close to the skin and helps release excess body heat. Perfect for high-intensity activities or if you naturally run warm.

Step 3: Activity level

What will you be doing?

Choose your base layer based on your activity level. High-intensity activities require good moisture management to prevent overheating, while lower-intensity activities require more insulation.

Will you be taking breaks?

Your choice of base layer also depends on whether you’ll be taking longer breaks during your activity, such as downhill skiing or hunting. To stay warm and comfortable during rest, a wool base layer is always preferable to cotton or synthetic alternatives.

Ullfrotté 200

Low-intensity or variable activities

If you’re planning lower-intensity activities, such as hiking or fishing, a warmer base layer is often the better choice.

Woolpower LITE

High-intensity activity

If you plan to engage in high-intensity activities such as running or skiing, a breathable base layer with good moisture management is essential to prevent overheating.

Step 4: Environment & temperature

Where and when will you use your base layer?

Where and when you use your base layer will influence your choice. Temperature, wind and moisture all affect how cold it feels. To simplify, you can think in two conditions: cold or mild weather.

Ullfrotté 200

Cold weather

Low temperatures where wind and moisture increase the cooling effect, placing higher demands on insulation.

Woolpower LITE

Mild weather

Higher temperatures where the cold is less noticeable and the need for ventilation and moisture management increases.

Which Woolpower base layer should you choose?

Ullfrotté 200

If you get cold easily, you need a base layer that insulates your body heat and keeps you warm.

Ullfrotté 200 is our classic base layer. The crimped wool fibers and our unique knitting method create an airy fabric with few contact points against the skin. The air trapped close to the body helps retain the heat your body produces.

  • You feel cold easily
