Merino is easier to care for than most people expect — and because it naturally resists odor, you'll wash it far less than cotton or synthetics.

Washing

  • Machine wash cold (30°C / 86°F) on a gentle or wool cycle
  • Use a mild detergent — no bleach, no fabric softener (softener coats the fiber and reduces its natural performance)
  • Wash with similar colors, inside out

Drying

  • Lay flat to dry away from direct sunlight — this keeps the shape and fit
  • Do not tumble dry, do not wring

Between wears

  • Air it out overnight — merino refreshes itself and is usually ready to wear again
  • Spot-clean small marks with cold water instead of a full wash

Storage & pilling

  • Store folded, clean and fully dry
  • Light pilling in high-friction areas during the first weeks is normal for natural fibers — remove it gently with a fabric shaver and it fades over time

MERINNOVATION Women's Merino Wool Leggings 165 Black with bonus neck warmer

100% Merino Wool Leggings Women - Thermal Underwear Base Layer Pants

THE MERINNOVATION STANDARD

Base-layer comfort, all-day pants

Merino joggers and leggings that move with you — training, travel, or the couch.

Warm without bulk
Merino insulates without the puffiness of fleece — layers under anything.
Fresh through repeat wears
Naturally odor-resistant, so one pair covers a whole trip.
Next-to-skin soft
No itch, no static cling — just soft natural fiber against your skin.
Move freely
Gusseted construction and natural stretch follow every stride.
Train in them. Fly in them. Sleep in them.

Train in them. Fly in them. Sleep in them.

Soft enough for the couch, technical enough for a cold-morning run, presentable enough for the airport. Merino keeps its shape and keeps you at the right temperature through all three.

Built around movement

Built around movement

A gusseted crotch removes the pull points, the wide waistband stays put without digging in, and the natural stretch of the knit follows squats, strides, and cross-legged sitting alike.

Good to know
Will it itch?

No. We use superfine merino fibers that bend on contact with skin instead of prickling it. If you've only worn traditional wool, the difference is immediate.

Are the leggings opaque?

Midweight 250 gsm is fully opaque and wears on its own. Lightweight 165 gsm is designed as a base layer — best under shells or shorts.

Do they bag out at the knees?

Merino has natural recovery — the knit springs back after wear. Lay-flat drying keeps the original shape for years.

How do I wash it?

Machine wash cold on a gentle cycle, lay flat to dry. No softener, no tumble dryer. Between washes, just air it overnight — merino refreshes itself. Full details in our care guide.

Wash less. Wear more. Merino resists odor naturally — air it out overnight and it's ready to go again. When it's time: cold wash, lay flat.
