How to Travel for a Week With One Merino Shirt
The case for packing less, looking sharp, and staying fresh — built around one merino button-up and a carry-on you don't check.
By Jock Merriman, Founder of Sir W. Merino
Here's a travel problem most people have just accepted: you pack a shirt for every day, plus a couple of spares, and you still arrive at your hotel looking like you slept in an airport. The bag is heavy, half the shirts come home unworn, and the ones you did wear needed a wash after a single day.
There's a better way to do this, and it comes down to the fibre.
A good merino shirt solves three of travel's most annoying problems at once: it keeps you looking presentable, it keeps you feeling fresh, and it lets you pack dramatically lighter. Here's how — and why The Bruce is the shirt I reach for every time I fly.
The problem with cotton on the road
Cotton is fine at home, where you change daily and have a wardrobe and a washing machine. On the road, its weaknesses get exposed fast.
Cotton absorbs moisture and holds onto it — it's literally the fibre we make towels out of. On a travel day, that means a cotton shirt soaks up sweat through a hot terminal, a rush to the gate, and a cramped flight, and then stays damp and clammy against your skin. By the time you land, it's done. It also picks up odour quickly, because the bacteria that cause smell thrive in that retained moisture. One wear and it needs a wash.
So you pack more cotton shirts to compensate. Which makes the bag heavier. Which is how you end up checking luggage for a four-day trip.
Why merino is the traveller's fibre
Merino wool does the opposite of cotton on every count that matters when you're travelling.
It manages moisture instead of holding it. Merino moves moisture away from your skin and releases it as vapour, so it keeps feeling dry even when you're working up a sweat running through a terminal. You stay comfortable through the parts of travel that make cotton miserable.
It resists odour. This is the big one for travel. Merino's fibre structure is naturally inhospitable to the bacteria that cause body odour, which means you can wear a merino shirt for several days between washes and it still smells fine. I wore one of our tees three days straight recently — a travel day and two workouts — and it was still fresh. That's not a party trick. That's the fibre doing what it evolved to do.
It regulates temperature. A travel day throws every climate at you: a freezing plane cabin, a hot jet bridge, an air-conditioned meeting room, a humid street. Merino's natural crimp traps air and helps regulate your body temperature across all of it. The same shirt that kept you warm on the plane keeps you cool when you step outside.
It looks presentable. Merino drapes cleanly and resists creasing far better than cotton. It won't come out of a bag looking like you ironed it — no fabric does — but what little creasing it picks up tends to fall out quickly once you put it on, and it reads as a proper shirt the moment you walk off the plane. You look like you have your act together, even when you've been travelling for fourteen hours.
The one-bag math
Here's where it all comes together. If a single shirt can be worn multiple days and still look and smell good, you simply need fewer shirts.
A week-long business trip in cotton might mean five or six shirts. In merino, two or three cover the same trip comfortably — wear, air out overnight, wear again. Sink-wash one if you want to, and it dries by morning because merino dries far faster than cotton.
Fewer shirts means a smaller bag. A smaller bag means you stop checking luggage. And not checking luggage means you walk off the plane and straight out of the airport while everyone else is standing at the carousel.
That's the actual luxury of travelling in merino. Not the fabric for its own sake — the freedom of moving through a trip light, comfortable, and presentable.
Why The Bruce is the one I pack
The Bruce is our merino wool button-up, and it's the shirt I reach for whenever I'm flying somewhere that matters.
It's versatile enough to carry a whole trip. Tucked into chinos with a clean pair of shoes, it works for the meeting. Untucked with jeans, it works for dinner. Sleeves rolled, it works for the flight. One shirt, several jobs — which is exactly what you want when you're trying to travel light.
It's woven from superfine merino at 17.5–19 microns, which is fine enough to feel soft and comfortable against the skin all day, and to do all the temperature, moisture, and odour work that makes merino the right fibre for the road.
Pair it with The George for a more casual day and The Cassius for the hotel gym, and you've got a week of travel covered in three shirts that all fit in a carry-on.
Or start with The Starter Set — all three, $35 less than buying them separately. It's a genuinely good travel capsule on its own.
The bottom line
Travel is hard enough without fighting your wardrobe. The right shirt means you pack less, look sharp stepping off a long flight, and stay fresh across back-to-back days without a suitcase full of laundry.
That's not a marketing claim. It's just what merino does — and it's the reason a fibre my family has grown for five generations ended up as the thing I trust most when I travel.

Frequently Asked Questions
Can you really wear a merino shirt multiple days without washing it?
Yes. Merino wool naturally resists the bacteria that cause body odour, so a merino shirt can be worn several days between washes and still smell fresh — especially if you air it out overnight. This is one of the main reasons merino is so well suited to travel and one-bag packing.
Does merino wrinkle when you pack it?
Merino resists creasing far better than cotton, and what wrinkling it does pick up in a bag tends to drop out quickly once the shirt is on and warmed by your body. No fabric comes out of a suitcase perfectly pressed, but merino looks presentable off a flight in a way cotton usually doesn't.
How many merino shirts do I need for a week of travel?
Because merino can be worn multiple days between washes, most people find two to three shirts comfortably cover a week-long trip — compared to five or six in cotton. That's what makes carry-on-only travel realistic.
Is merino too warm for summer travel?
No. Fine merino regulates temperature in both directions — it insulates in the cold and releases heat and moisture in the warmth. A lightweight superfine merino shirt is comfortable in hot climates and on cold plane cabins alike, which is exactly why it suits travel.
How do I wash a merino shirt while travelling?
Merino rarely needs washing on a trip thanks to its odour resistance, but if you want to freshen one, a quick sink wash with a little soap works well. Merino dries faster than cotton, so a shirt washed in the evening is usually dry by morning.
