The COTECi 86020-BK sleep mask stands out for its innovative double-sided design, which perfectly adapts to the temperature changes throughout the year. One side is made of a special fabric that provides an immediate cooling sensation, reducing sweating on hot summer nights. Conversely, the other side retains heat, offering a warm and soft texture that protects you from the cold of winter.

Designed with the aim of complete isolation from the external environment, the mask offers 100% effective blackout. It fully blocks sunlight, street lights, or electronic devices, helping the brain to secrete melatonin faster. It is ideal for those who work night shifts, people sensitive to light, or those who want to relax in the office.

In timeless Black / Black color, this mask combines elegance with absolute practicality. Its materials are extremely lightweight and friendly to the sensitive eye area, preventing irritation and pressure marks on the face. It features an adjustable elastic strap for a perfect fit on every head, making it the ultimate companion for travel by plane or train.
