Layering Guide

Base layers are your first layer, right next to your skin. You want base layers to wick away perspiration, so you don’t get chafed or chilled.

Base layers can range from lightweight to heavyweight and come in synthetic or natural fibers.

Synthetics such as polyester are lightweight, breathable, and durable, good for high activity levels and warm temperatures.

Wool is naturally odor resistant and retains its warmth when wet, so it can tackle cold, damp conditions.

The main job of middle layers is to keep you warm. Like base layers, middle layers come in a variety of materials and weights. Fleece and insulation are popular choices for middle layers.

Synthetic fleece provides a soft, warm, and durable midlayer. It is not usually water- or windproof, so severe weather might require another defensive layer.

Insulated, aka “puffy,” layers use down or synthetic fill. Down offers the best warmth for its weight and compacts easily so you can stow it away. Because down loses Its insulating power when it gets wet, it works best in cool, dry climates.

Synthetic fill is not as light or compressible as down, but it retains heat even when it’s damp, so it reigns supreme in wet conditions.

Outer layers, also called shells, protect you from the elements. Shells come in a spectrum of styles, from serious technical gear to minimalist layers with just a touch of protection.

Technical shells boast waterproof, windproof, and breathable properties. Their magical fabrics can repel storms on the outside while still allowing for perspiration to escape from the inside.

An insulated shell combines a middle and outer layer in one, for extra warmth and protection.

Water-resistant/breathable shells are usually lighter than waterproof shells and suit damp conditions when your activity level is high.

Wind shells range from lightweight to ultralightweight and supply just the needed amount of barrier.

Stretchy and highly breathable, soft shells work well for high output activities. They may have light wind and rain resistance and medium-weight insulation.

Dial in your layering combinations and you’ll regulate your temperature, protect yourself from the elements, and be ready for whatever adventures cross your path.
