Designed for longevity, crafted for comfort.

Wash: Machine wash cold (max 30°C) on a delicate cycle with similar colors.
Dry: Do not tumble dry. Reshape while damp and air dry flat to prevent shrinkage.
Iron: Iron on a low heat setting, preferably on the reverse side.
Handle with care: Avoid rough surfaces and sharp jewelry to prevent snagging.

Sustainability Note: Washing at lower temperatures and air drying not only extends the life of your wardrobe but is also kinder to the planet.
