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.
Are they suitable for skiing?
Our women’s thermal base layers use breathable, moisture-wicking fabrics that trap heat without bulk, making them ideal for skiing, snowboarding, and cold-weather adventures.
How should they fit?
They should be supportive but never tight. With 360-degree stretch, a sculpting fit, and no bulky seams, our top sits smoothly under jackets and jumpers or shines on its own in milder weather.
