What is a base layer, and why is it important for outdoor activities?
A base layer is your first layer of protection against the cold, designed to wick moisture away from your skin and regulate body temperature. Our thermal base layers are made from GRS® certified recycled fabric that’s lightweight, breathable, and warm, keeping you dry and comfortable whether you’re skiing, hiking, or adventuring outdoors.
What are the best materials for thermal base layers?
The best base layer materials offer a balance of warmth, stretch, and breathability. Our thermal base layers are made from ultra-soft, GRS® certified recycled fabric that's gentle on your skin and better for the planet. They’re built to keep you warm, wick away sweat, and stand up to every adventure.
How should base layers fit for maximum performance?
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 thermal base layers be worn on their own?
Definitely. Our thermal base layers are made to perform, and look good while doing it. With their buttery-soft feel and flattering fit, they’re perfect for wearing solo during mild conditions, après activities, or layering up when the temperature drops.
