Who is Sir W? 🐏

At Sir W. we don’t just make clothes—we craft modern essentials from the world’s finest natural fiber: Australian Merino wool. Our garments are soft, breathable, and odor-resistant by nature—not by chemicals.

Just timeless, high-performance knitwear built to outlast trends and outshine synthetics.

Clothing With Heritage

Our founder, Jock Merriman, grew up on his family’s Merino sheep farm in Boorowa, Australia, carrying forward a four-generation legacy.

Jock founded Sir W. Merino to share the unmatched performance, comfort, and sustainability of Merino wool with the world—blending heritage with modern design.

Such a lightweight comfortable shirt and doesn’t make me sweat.

I love how breathable it is during the hot summer months, but I’ll wear it year round too.

The shirt has some of the nicest material I’ve ever worn. I get so many compliments wearing it. It’s the type of shirt that just shows you’ve got some taste.

I find myself wearing it all the time. Date night with my girlfriend, weekends out with friends, and even to the office!

I didn't know much about Merino wool until I discovered Sir W. Now I literally choose it every time I pick something to wear for the day!

It's exceptional for every day of the year!

Merino wool isn’t just a fabric.

It’s a legacy—one that began centuries ago and continues today with the world’s finest wool grown by dedicated farmers and thoughtful stewards of the land.

Merino sheep were originally bred to survive and thrive in extreme climates. Over generations, careful selection created a unique fleece: fine, soft, and breathable. Today, Merino wool remains the gold standard in natural performance fibres.
