The Softness of Merino, Measured in Microns
The quality of Merino wool is defined by fiber diameter, measured in microns, where smaller means softer.
Unlike many Merino brands, we focus on finer Merino wool, prioritizing the softest, most refined fibers to create an experience of comfort that lasts.
Merino Made for Travel Days.
- Superior double-knit fabric that’s unbelievably soft on your skin.
- Handy front pockets to stash travel essentials.
- Naturally insulates but keeps you from overheating.
- Merino wool’s antibacterial properties means minimal washing.
- Lightweight and packable for easy travel.
As featured in
Nature’s Miracle Fabric
Every Merino wool fiber has a waxy coating called Lanolin, which helps wick moisture away from your body and acts as a safeguard against odor-causing bacteria. This allows our Merino to stay breathable and dry while smelling and feeling fresh, no matter what you put it through.

SOFTER THAN COTTON
This wool isn’t like your typical itchy sweater. We only use superfine Merino wool, resulting in a luxurious, silky soft feel that’s lighter and plusher than your average Merino or cotton. And unlike most clothes these days, it'll also maintain its form over time and won't get ruined after a wash.
Regulates Body Temperature
Whether you’re landing in Seoul or Santiago, the natural fibres of Merino wool are excellent when it comes to regulating your body temperature. The breathable material retains warmth, but not to the point of overheating, providing optimal comfort in any condition.
Cozy Softness
Modern spinning technology has made Merino wool the softest, most luxurious of all wool types. Perfect against your skin, the fibers will never itch or irritate, outclassing any and all synthetic fibres.
EASY CARE
You won’t have to wash this item much at all. However, when it comes time for a refresh, simply add it to your load on a warm, gentle setting, then lay flat to dry.
ABOUT OUR WOOL

- Woolmark® certified Merino wool means you can expect the highest standards related to fiber content, performance, color fastness, and dimensional stability.
- Made in Green OEKO-TEX® certified which guarantees this item was manufactured in environmentally friendly, socially responsible facilities.

Can wear a dozen times without washing. Just hang on a hook to let sweat dry and it’s as good as new. This thing is magic.

Perfect for Travel
YOU’LL PACK LIGHTER
With clothing that doesn’t smell after every use, you can pack less, allowing you to ditch the suitcase and travel with just a small backpack.
YOU’LL SAVE MONEY
These days, most airlines are going to charge you for anything other than a carry-on. Start packing lighter and doing less laundry, and save your money for the real experiences.
YOU’LL SAVE TIME
Never check luggage or worry about airports losing your stuff. With fewer but better clothes you’ll blaze through airports like a seasoned pro.
