CLIMAFORCE Merino, the next generation of merino wool.

Merino wool, but more durable!

When it comes down to comfort and performance, merino wool ticks all the boxes. But we found that some merino T-shirts are a bit more fragile than your standard cotton counterparts. So it became our mission to develop the merino T-shirt that lasts.

Why choose merino wool?

Thermo regulating

Merino wool is fashion’s natural climate regulating system. The breathing qualities of the fabric hold great advantages when it comes to comfort. Merino wool is perfect for all-year-round clothing.



When it’s hot, the fibers absorb your body’s moisture vapors and evaporate them outside of the fabric – keeping you nice and cool.


But in wintertime, these moisture vapors condense inside the fiber, giving off heat and keeping you nice and warm.

No odor stay fresh

Great news for all people dependent on deodorant: merino wool absorbs all odor molecules and only releases them upon washing. No matter how hot it is, you’ll feel fresh all day long. Your merino wool T-shirt or shirt will not smell like cotton shirts do. And on top of that, you don’t need to wash it each time you’ve worn it. Just hang it in the open air – and enjoy it again the next day.

Wrinkle resistant

The elastic properties of the merino fiber make it extremely wrinkle resistant. If you hang your shirt to dry, Ironing becomes optional. And when you’re travelling with a packed suitcase, just get out your merino wool clothes, hang them for half an hour and you’re all good. No annoying wrinkle damage from seatbelts or backpacks any more. It’s the ultimate on-the-go companion.

Quick to dry

Merino wool is a surprisingly fine fabric, that releases water easily. It’s dry long before your other garments are. Just put it in the machine, dry flat or place it on a hanger and wear it again in no time!

Non allergenic

Merino wool does miracles for style-lovers with sensitive skin. Research shows that wearing merino wool T-shirts or sweaters reduces adult and infant eczema symptoms impressively in comparison to other fabrics. This hypoallergenic fiber treats your skin softly and with great care.

No itching

When we say wool, and you think Grandma’s-Itchy-Christmas-Sweater?

Then we have news for you! The superfine merino wool fibers are only 17 microns thick. In comparison, a human hair is between 60 and 180 microns in thickness. Merino wool is more flexible, bends softly against your skin and doesn’t itch one bit.

Machine washable

The natural protective outer layer of your merino wool sweater or T-shirt will prevent stains from being absorbed. However, when your favorite item is dirty, just wash it on low temperature. Not sure how to start? Check the handy care label inside your garment!

Extremely durable

Merino wool is 6 times stronger than cotton. Each fiber can be bent back on itself over 20.000 times. Cotton breaks after 3.200 times. Poor cotton. Lucky merino wool T-shirt owner!

UV resistant

The natural UV-barrier of the fabric keeps you safe from damaging UV-radiation from the sun – unlike synthetics and cotton. Good for worry-free summer times!

Merino wool is sustainable


Synthetic fibers and cotton demand a great amount of manipulation and processing. Merino wool, however, is made of grass, water and fresh air. The merino sheep graze the hills of New Zealand and Australia freely, delivering a new fleece harvest twice a year.


The Merino fiber will naturally decompose in soil when it is disposed. It will give back it nutrients into the earth.
