Warm Leggings, Long Johns & Tights Made of Merino Wool

Good quality thermal leggings and long underwear should be comfortable no matter what. This means they’re warm, but breathable, with the right amount of stretch and a flattering design. Merino wool is an amazing textile that can adapt to the temperature, trapping heat in its fibers more effectively than synthetic fabrics. When you get hot, the wool absorbs moisture and dispels it away from your body, keeping your legs cool and dry.

This makes them the perfect base layer for year-round everyday use, trapping or expelling body heat as required. Wear them beneath shorts,wool pants, or on their own.

Merino Wool is the Ultimate Comfort Material

What makes merino wool the best fabric for thermal leggings or long johns? Not only does it have amazing body temperature regulating properties, it's also super soft, providing a luxurious skin-feel. Your body will be grateful that you chose Smitten Merino.

Sustainability is important to us throughout the supply chain. Your garments are made at the most environmentally responsible merino knit manufacturer in the world. Your order is always packed and shipped in biodegradable packaging, promoting a zero-waste approach to fashion. When your thermal leggings arrive, you can feel good knowing they were made thoughtfully for you, with sustainability and ethical standards in place every step of the way.
