130 years of Merino

Clothing With Heritage

Sir W. Merino is all about the beauty of Australian Merino wool, carefully selected to combine elegance with everyday comfort. Founded by Jock Merriman, who comes from a family with a long history of Merino wool farming, our story began with a deep love for this unique material. Born and raised in rural NSW, Australia, we cherish the rich heritage that shapes our brand.

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.

Andrew C- NYC

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!

Evan V- ATX

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!

Move Away From Plastic Clothing

65% of all clothing today is made with plastic; polyester, nylon, acrylic. So we present you the better alternative.

Made with Merino wool that is 3x finer than other wool. Our products mirror the performance of the sheep it was grown on. Originally bred to survive and thrive in extreme climates. Merino sheep created a unique fleece: fine, soft, and breathable. Today, Merino wool remains the gold standard in natural performance fibres.
