The 4 steps of layering for an active lifestyle

Layering is the best way of managing heat and humidity when outdoors. There are endless combinations of layers, depending on conditions and activity. In this guide, we will go through the 4 core pillars of layering, base layer, midlayer, outer layer and insulation.


Why is layering correctly important during outdoor activities?


When we are outside and moving our bodies, we create heat and humidity. Humidity between your layers is a significant problem, and every type of performance fabric tries to address this differently. The biggest issues are how humidity impacts the fabric’s function and the consequences that follow.

When the fibers of a fabric become moist, the fabric allows less air to pass through it, leading to even more humidity being trapped. The trapped humidity draws heat from the body and can lead to excessive cooling. In freezing conditions, this problem becomes even worse, as humidity can form ice crystals, which makes the fabric stiff and lose its elasticity.

This is why humidity needs to be actively managed when the amount of insulation is increased, and the right type of layers need to be added. A good rule of thumb is: 1. A base layer to remove excessive moisture. 2. A midlayer with warmth and wicking effects. 3. A protective outer layer. 4. For cold, dry days, a down jacket can be added for extra warmth. But the best part of layering? It is fully modifiable to suit your exact needs.

1. Base Layer

1. Core Comfort with Base Layers

The base layer works as a second skin and is there to keep you comfortable and dry. The fit should be close-to-body for the best effect. For this purpose, our base layers made of Organic Merino Wool are an outstanding choice of material thanks to its moisture-wicking effects, silky touch and quick-drying characteristics. Together with a mix with Tencel™ for stretch and durability, the Organic Merino Wool really shows its best side.

2. Midlayer

2. Complete Temperature Control with Versatile Midlayers

Control your temperature with the correct midlayer. By picking one with wicking effects, such as one made from wool or PrimaLoft®, the humidity is continuously removed, and your temperature will stay on a comfortable level throughout your entire activity. The fit should allow for movement but be close enough to the body to add warmth, and a slim base layer should fit underneath. All of our zipped midlayers also feature a two-way zip for ultimate temperature regulation.

3. Outer Layer

3. Protection with Durable Shells

Breathability, wind and water protection, and technical details in different combinations make an optimal shell that fulfills your needs. Klättermusen shell jackets, made from sustainable materials, are created to last, season after season. Our shell jackets have been created with an intended usage in mind and this is reflected by the material and fit. Your shell should provide enough room for your base layer and midlayer, but not be too big to allow cold air to find its way in under the hem.

Most of our shells have ventilation zips for temperature regulation, without direct exposure to adverse weather, slanted zippers to avoid abrasion when layering, pre-bent elbows, and a 3D-adjustable hood. The Shell Jacket Guide will help you find the right shell for your needs.

4. Insulation

4. Responsible Thermal Insulation

When the cold hits, a warm layer of down can be added. Klättermusen’s down insulation pieces are packable and can be worn as an outer layer, on top of your shell, or as a midlayer underneath. Down is sensitive to humidity, both internally and externally, which impacts the thermal performance. Therefore, it should only be worn in dry conditions to maintain its thermal effect. We only use down certified with RDS (Responsible Down Standard) with a minimum of 750+ fill power.

Our down pieces are constructed to act as a natural part of our systems. The instantly recognizable shoulder yoke offers protection from snow or light rain and the wear of shoulder straps, while the neck opening is slanted for simple integration with both inner and outer layers.
