Have you ever worn clothes that keep you warm when it's cold, cool you when it's hot, and feel super soft against your skin?
Meet Merino wool, a natural fiber from the Merino sheep. Merino wool has several unique properties that make it particularly suitable for everyday T-shirts:
-
Breathable and temperature-regulating - Merino wool conforms to your body, keeping you cool in the heat and warm in the cold.
-
Odor Resistant - Thanks to its natural antibacterial properties, Merino wool stays fresh for longer, even after several days of wear.
-
Soft and comfortable on the skin - The fine Merino fibers (such as 17.5 micron) feel super soft.

Clothes that don't distract
Merino wool's properties make it particularly suitable for people who spend a lot of time outdoors, enjoy comfort without distractions, and strive for a more mindful lifestyle. Merino wool is also ideal for active people who hike, cycle, travel, or play sports. Its natural ability to retain warmth and dissipate excess heat keeps you comfortable in all weather conditions. Sweat is quickly wicked away, keeping you dry and smelling fresh for a day (or three). This makes Merino perfect for longer trips or hikes where washing is limited. Simply air it out and you're good to go.
Gentle on your skin
Even those with sensitive skin feel at home in Merino wool. Rhinowool uses extra-fine merino fibers just 17.5 microns thick, thinner than a human hair. This gives the fabric a silky-soft feel, without the prickly or itchy sensation you might experience with regular wool. This fineness makes our Merino perfect as a base layer: directly against your skin, all day long.
Cool in summer, warm in winter
What makes Rhinowool's Merino wool especially suitable for everyday use is its 150 grams per square meter (gsm) fabric thickness . This density offers the ideal balance between warmth and breathability. Light enough to wear year-round, warm enough for crisp mornings or an autumn walk. In the Dutch climate, where it's often just between summer and winter, 150 gsm is just right. Not too thick, not too thin, but precisely the flexibility you're looking for.
Merino with a good story
And then there's something just as important as comfort: how and where your clothes are made . Many brands opt for cheap wool from low-wage Asian countries, where animal welfare is poorly monitored and mulesing is still common. That doesn't align with how we work. Rhinowool consciously chooses a different approach. We use only high-quality, mulesing-free merino wool , sourced from controlled, animal-friendly farms. All our clothing is made in Portugal under fair conditions, with a focus on quality and sustainability . No mass production, no compromises.
In short: Merino wool is for everyone who makes conscious choices. For those who want comfort without compromise and value clothing that feels good, both literally and figuratively. Whether you're on the go, exploring nature, or simply working from home: with Merino wool from Rhinowool, you're always in good hands.
