FAQ's

What makes a wool sleep mask different from regular sleep masks?
A wool sleep mask, especially one made from merino wool, offers natural warmth and breathability. Unlike synthetic masks, wool helps regulate temperature, keeping you cozy without overheating, perfect for cooler nights.

Why choose a merino wool eye mask for sleep?Merino wool is soft, lightweight, and hypoallergenic, making it ideal for sensitive skin. Our merino wool eye mask provides gentle warmth while blocking out light, helping improve sleep quality.

How does the Stay Warm Sleep Mask keep me warm?The mask uses premium merino wool that traps heat close to your skin while allowing moisture to escape. This balance keeps your eye area comfortably warm without feeling stuffy.

Can merino masks help if I sleep in a cold environment?
Absolutely. Merino wool masks are excellent for cold bedrooms or winter travel, providing soothing warmth that promotes restful sleep.

How do I care for my wool sleep mask?
Handwash your sleep mask. Do not tumble dry. Do not bleach. Do not dry clean.
