Why Merino Wool Became My Favourite Travel Clothing After a 38-Hour Journey

I’d heard people rave about merino clothing for years, especially travellers and hikers, but I always wondered whether it was genuinely worth the hype — or just expensive basics with good marketing.
After our recent trip from Auckland to Munich, I finally understand why so many people swear by it.
Our journey took roughly 38 hours door-to-door, with long-haul flights and airport stops through Los Angeles and Copenhagen before finally arriving in Germany. For the trip, I wore merino underwear and a merino polo shirt almost the entire way.
Honestly, I don’t think I’ll go back for long-distance travel.
The Biggest Difference: Feeling Fresh the Entire Journey
Normally after long flights I feel sticky, stale, wrinkled, and desperate for a shower and a change of clothes.
This time was completely different.
Even after nearly two days of travelling, the merino still felt surprisingly fresh. I never got that sweaty synthetic-clothing feeling you often get on planes or during airport transfers.
There was no clammy feeling sitting in airport lounges. No cold, damp feeling after sleeping on flights. No “travel stink” building up hour after hour.
It genuinely stayed comfortable the whole way.
Much Better Temperature Control
One thing I noticed immediately was how well merino handled changing temperatures.
Airports and planes constantly swing between:
hot boarding gates
freezing air conditioning
warm train stations
chilly early mornings
crowded terminals
Usually I’m either too hot or too cold.
Merino seemed to balance everything out naturally. It stayed warm when needed but never overheated. Even during long periods sitting on flights, it remained breathable and comfortable.
It also had a really nice snugness to it — comfortable without feeling tight or restrictive.
Looking Tidier Without Trying
Another unexpected benefit was simply looking more presentable.
After long travel days, normal cotton shirts usually end up wrinkled and stretched out. The merino polo held its shape much better and still looked tidy when we arrived.
That might sound minor, but after a huge travel day it actually makes a difference mentally too. You feel more put together instead of looking like you’ve just survived an endurance event.
The Best Part: Arriving Feeling Human
The biggest moment for me was arriving and seeing family after not seeing them for such a long time.
Usually after a trip like that, the first thing I want is a shower before hugging anyone.
This time I genuinely didn’t feel gross.
I still felt comfortable, fresh, and presentable enough to enjoy the arrival properly instead of immediately thinking about changing clothes and cleaning up.
That alone made the merino worth it.
Is Merino Worth the Price?
For everyday wear, maybe not everyone needs it.
But for travel? Especially long-haul flights? I can absolutely see why people invest in it.
Less smell. Better comfort. Better temperature regulation. Looks tidier for longer. Feels fresher after huge travel days.
For us, it’s quickly becoming one of those travel items that feels less like a luxury and more like a genuinely useful upgrade.
