I packed one shirt for a week

Five days. One shirt. Here's each day, honestly.

No spare tees, no detergent, no mid-trip wash. Just merino doing the thing cotton never could.

Day 1Packing

I put one merino tee in the bag and zipped it. No stack of spares, no “just in case” pile.

Pack one, not seven

Merino doesn’t need a wash after every wear, so one shirt covers days. Fit a week into a carry-on and walk straight past the baggage belt.

Day 2Trail to table

Hiked in the morning, sat down to dinner in the evening — same shirt, no change of clothes.

Trail at noon, table at night

Clean lines, no logos: casual with jeans, sharp under a jacket. Merino regulates temperature and blocks UV (UPF 30+), so one shirt works from a July city to an October ridge. Seven colours, nothing branded.

Day 3The sniff test

Three days in the same shirt. Sniff test before heading out, braced for the worst. It smelled of nothing.

The shirt you can’t out-sweat

Merino is naturally antibacterial: it resists odour instead of trapping it the way cotton and synthetics do. Days of wear, still fresh. Not masked — just not there.

Day 4No laundromat

Everyone else was hunting for a laundromat. I wasn’t.

Skip the wash entirely

Because it stays fresh, you wash it a fraction as often — no sink-washing in the hotel, no packing damp clothes home. Fewer washes also means the shirt lasts longer. When it’s time: cool wool cycle, lay flat.

Day 5Homeward

Fifth day in the same shirt, against the skin the whole time. Still soft, still no itch.

Soft enough to live in

At 17.5 microns this is next-to-skin soft — none of the scratch people expect from wool. Mulesing-free, because, the way we see it, happy sheep don’t itch.

A note from the owner

I didn't start Thermowave. My family did.

It began in 1928, in Lithuania, with two sewing machines and two seamstresses. Over the decades our workshop made base layers for cosmonauts, and for divers working two hundred metres down. In 2013 my mother handed the company to me.

We still make everything ourselves, here in Lithuania — we spin the yarn, knit, dye, sew and pack it all under one roof. We call it our 0 km rule. The wool is mulesing-free, because, the way we see it, happy sheep don’t itch.

The Merino Life Tee is the one I actually travel in — one bag, one shirt. I hope it earns a place in yours.

Wear less. Pack less. Wash less.

One shirt that does the work of half your suitcase.
