If you need a high-performance, durable base layer for outdoor activities or sports, Merino Skins is the ideal choice with its flatlock stitching and higher necklines for extra coverage and style. For everyday warmth and comfort, especially indoors or under work clothes, Thermo Fleece offers a more relaxed fit with lower necklines designed to stay hidden.

Have used these for almost a year now, and they’re so comfortable. As a mens’ size 32, I chose Medium size, and it fits great. The fabric is substantial, yet feels light & breathable. It appears to loosen slightly at the leg openings as I move about throughout the day; but after washing and drying on clothes line, the leg openings become form-fitting again, which I love.
Best underpants ever for Tasmania
Very comfortable, best boxers shorts I’ve tried.
Very good
Far superior to any other trunks I’ve ever worn. Great, thick wool yet super comfortable.
