Base Layer Long Johns, Track Pants and Thermal Underwear for Men

Smitten Merino

Spun from super-fine merino, our wool is sourced from Tasmanian and Australian premier wool growing regions. It’s our passion to provide you with garments that are natural fibre, sustainable, and environmentally aware.

All our merino wool is sustainably grown and from non-mulesed sheep.

Our manufacturing procedure undergoes a stringent process before it touches your body; cleaning and spinning, colouring, design, machining, construction and quality control. The end result, a product that looks and feels better, lab tested in our own Tasmanian backyard.

Let yourself experience a little piece of luxury that will stand up to all conditions.

Keeping your legs warm and protected from the elements will contribute to your overall performance and ability to get on with the task at hand.

Our lightweight 100% merino wool base layer clothing has been put to the test in some of the wildest places on Earth. From the intense heat of the Mekong Jungle to freezing expeditions in the Arctic Circle – Smitten Merino has been a favourite with athletes and adventurers for years.
