Stay Comfortable in All Weather by Layering Your Clothes (2025)

Layering in clothing is a straightforward concept involving the addition and removal of clothing layers to maintain comfort in varying weather and temperature conditions. The practice, despite extensive efforts and investments made to optimize it commercially, essentially boils down to adding layers when cold and shedding them when warm. The key lies in selecting the appropriate layers. This guide aims to explain the different types of layers, how to effectively layer them, and when each is necessary. Additionally, resources such as guides to the best puffer jackets, merino wool clothing, and rain jackets are available for further information.

The foundation of layering involves understanding the purpose of each layer and knowing when to adjust them. The general structure consists of:

1. Base Layer: This is the layer in direct contact with the skin. It provides warmth and, crucially, wicks sweat away from the skin to avoid dampness, which can lead to feeling cold.

2. Mid Layer: Positioned between the base and outer layers, the mid layer serves as the primary insulator. It can consist of multiple layers like a lightweight fleece paired with a puffer jacket.

3. Outer Layer: Also known as the shell, this layer is both waterproof and windproof, protecting the retained heat from the mid layer from being lost to the environment.

While it’s not always necessary to don all three layers, especially during physical activity like walking or running, having them on hand is often beneficial. In colder conditions, starting with all three layers and removing them as needed can be effective, whereas in warmer conditions, a shell may be added when stopping in a windy area. Of course, certain scenarios do not require all layers, such as hiking in warm climates where the mid layer might be unnecessary.

Starting with underwear, the base layer should consist of moisture-wicking materials. Merino wool is often preferred for underwear due to its moisture-wicking properties, but other fabrics may also be suitable depending on personal preference.

The primary base layer, typically comprising snug but not restrictive pants and a shirt, serves the dual purpose of providing insulation in the cold and removing sweat in the heat. Merino wool is favored here for its natural ability to moderate temperature, but alternative fabrics like Nuyarn—merino wool blended with nylon for added strength and quicker drying—are also options. While synthetic base layers tend to dry quickly and are often more affordable, they may not insulate or manage moisture as effectively as natural fabrics.
