Base Layers Frequently Asked Questions

What does a base layer do?

Base layers are garments worn closest to the skin, providing insulation, moisture management and temperature regulation. They are essential for outdoor activities like hiking, skiing and running. Base layers can be made from various materials, including wool, synthetic fibers and merino wool, each with its own benefits and drawbacks.

What is the difference between thermals and base layers?

Thermals and base layers are often used interchangeably, but there can be subtle differences. Base layers are specifically designed to be worn closest to the skin, providing moisture-wicking properties and temperature regulation. Thermals can be a type of base layer, but they may also refer to any garment that provides warmth, including heavier-weight options that might not be ideal for wearing directly against the skin.

Do base layers need to be tight?

Base layers should generally be a snug fit, but not overly tight. A tight fit helps to trap heat and regulate body temperature effectively. However, if the base layer is too tight, it can restrict movement and reduce comfort. It's important to find a balance between a snug fit and freedom of movement.
