Merino Wool Thermals for Cold Weather

Merino wool thermals are the ultimate choice for outdoor comfort during colder months. Soft, insulating, and breathable, they’re ideal for activities like hiking, walking or skiing. Designed to wick away moisture, thermals keep you dry and comfortable while offering natural odor resistance for long-lasting freshness.

Why Use a Merino Wool Base Layer

The foundation of any effective layering system, a merino wool base layer regulates your body temperature and manages moisture effortlessly. Instead of wearing one bulky item, layering allows you to adapt to changing conditions with ease. Base layers are super versatile and come in different fabrics and styles suited to various climates, conditions and activities. Derived from Merino sheep, these wooly base layers are highly effective at keeping you warm in cooler temperatures."
