Base layer
Overview
A base layer is the layer of clothing worn next to the skin, typically designed to manage moisture and provide a comfortable interface between the body and outer layers.
Key points
- Common materials include synthetic fabrics and wool blends designed for wicking and comfort.
- Used in a range of temperatures as part of a multi-layer clothing system.
- Base layers vary in thickness, fit, and intended activity level.
Details
In layering systems for hiking and backpacking, base layers form the foundation. They are worn directly against the skin on the torso and sometimes the legs, with goals of moving moisture away from the body, moderating temperature, and reducing friction from pack straps or outer garments. Different weights of base layers can be chosen for warm, cool, or cold conditions, and many hikers adjust combinations across a trip. The term covers a wide variety of garments, from lightweight short-sleeved tops to heavier long underwear, unified by their position against the skin within a broader clothing system.
