What is a base layer, and why is it important?
A base layer is your first layer of protection against the cold, designed to wick moisture away from your skin and regulate body temperature.
How should base layers fit?
A well-fitting base layer should feel close to the skin without being restrictive. Ours are designed to move with you, offering a flattering, second-skin feel that keeps warmth in and moisture out. Perfect for layering or wearing solo on milder days.
Can base layers be worn on their own?
Definitely. Our thermal base layers are made to perform, and look good while doing it. They’re perfect for wearing solo during mild conditions, après activities, or layering up when the temperature drops.
