FAQs

How to use merino wool base layer bottoms for optimal warmth?
Wear your merino wool base layer bottoms directly against your skin for maximum comfort and thermoregulation. Layer with other winter gear as needed, and ensure a proper fit to prevent sagging and chafing.
How to clean and maintain thermal underwear men made from merino wool?
Wash in cold water on a gentle cycle, avoid bleach, and lay flat to dry. Proper care preserves the natural odor resistance and durability of your merino wool base layer.
What makes the best merino wool base layer for skiing?
Look for midweight merino wool with flatlock seams and a comfortable fit. The breathable, moisture-wicking fabric keeps you dry and warm during high-intensity winter activities.
