100% Merino

We use 100% Merino, so you get 100% softness.

1880

That's the year our family began growing Merino wool in Australia.

100% Natural

Merino is a natural fibre made from a structural protein called keratin.

Founder of Sir W. Merino, Jock Merriman sits in a shearing shed with a Merino wool fleece.

Our Heritage

Merino wool and family since 1880.

In 1880, George Merriman purchased a small flock of Merino sheep. This was the beginning of a family legacy now over a century long.

In 1903, his son and my great-grandfather, Walter Merriman received a portion of that flock for his twenty-first birthday. From that small beginning, he built one of Australia's most respected Merino studs, was knighted by the Queen of England — and many generations later, we still graze the same bloodline of sheep.

Sir W. exists to share that wool with the rest of the world. As a proper, better way to dress through life.

The Math

Here’s why Sir W. makes sense.

What you’re actually buying versus what you’d buy otherwise. We did the math so you don’t have to.

Wears between washes 5–7 1–2 1
Holds odour Naturally resists Yes, by day 2 Yes, traps it
Wrinkles in a carry-on Drops out overnight Heavily Some

Cost per year (over 5 yrs) $25 $30 $50

A $125 Merino shirt that lasts five years runs cheaper per year than the cotton ones you keep replacing.

Why Choose Sir W. Merino?

Cotton holds odour and wears thin, and polyester traps heat. Merino does what clothing should — and it's been doing it for thousands of years.

Antibacterial.

Naturally antibacterial. Most owners wash every 5–10 wears instead of after every use.

Temperature regulating

Cool when it's hot, warm when it's cold. One shirt for every climate you'll travel through.

No odour, ever

Fine merino fibres prevent the bacteria that cause smell from taking hold in the first place.

Plastic-free

100% natural, renewable, biodegradable. No synthetic blends, no microplastic shedding.

"The Cassius is such a nice shirt. My husband loves the feel and he can workout in it and there’s no odor at all!"

Christi F.

"I recently bought this shirt after having the George shirt for over a year. It’s a great shirt for workouts or to wear for casual social events when the weather is super hot or humid. It sounds crazy but it doesn’t smell when you sweat in it so it’s perfect for summer and workouts!"

Tommy C.

"Love this shirt, I wear it everywhere. It can dress up or down and requires very little washing."

Jack N.

"Bought as a gift and is highest quality, elegant, and makes him look distinguished!"
