FAQs

Not at all. Unlike traditional wool, Merino wool is incredibly fine—ranging between 15 and 21 microns—so it bends softly against the skin. That means no itch, just pure comfort. In fact, it’s soft enough to wear directly on your skin.

Yes. Merino fibers naturally resist odor-causing bacteria, meaning you can wear it multiple times between washes and still smell fresh. It’s perfect for travel, workouts, or long days out.

GSM stands forgrams per square meter, a measure of fabric weight. A higher GSM means a denser, heavier fabric. For Merino, lower GSMs (like 150–180) are ideal for lightweight summer shirts, while higher GSMs (200–300) are used for warm winter layers.

Absolutely. Merino wool is thermoregulating, which means it keeps you cool when it’s hot and warm when it’s cold. It’s breathable, moisture-wicking, and naturally UV-resistant—ideal for summer.

Merino is breathable like cotton but performs far better. It keeps you dry, resists odor, and adapts to your body temperature. Unlike synthetics, it doesn’t trap odor or rely on plastic. It’s nature’s high-performance fiber.

Regular wool is ticker and will feel coarse and heavy.

Merino wool is finer, softer, and more flexible. It’s suitable for garments worn next to the skin and offers performance benefits like moisture-wicking, odor resistance, and temperature regulation.

Merino is 100% natural, biodegradable, and renewable. Our wool comes from sheep that regrow their fleece every year. When you choose Merino, you’re choosing clothing that treads lightly on the planet.

Washing

Merino wool doesn't need constant washing. It's naturally odor-resistant and antibacterial.

When it’s time:

• Machine wash cold on a gentle or wool cycle
• Use a mild, wool-safe detergent
• Avoid bleach and fabric softeners
• Wash with similar, soft fabrics—no rough towels or denim

Drying

Never tumble dry.
Heat can damage or shrink Merino fibers.

Instead:

• Gently reshape after washing
• Lay flat to dry—not in direct sunlight
• Don’t hang wet garments (it can stretch them)

✨ Wrinkles & Ironing

Merino naturally resists wrinkles, but for a touch-up:

• Use a cool iron on the wool setting
• Or simply steam while you shower—it works wonders

Storing Your Merino

• Fold, don’t hang—especially heavier pieces
• Keep away from direct sunlight
• Store clean and dry
• For long-term storage, use a cotton bag (not plastic)

What About Pilling?

Some light pilling is natural—especially with friction.

To fix:

• Gently use a fabric comb or pilling razor
• Never pull pills by hand
• Over time, proper washing will reduce future pilling
