For Sleeping, Mask Compatible, Skiing, Commuting, Outdoors, Compact [Functional Beauty for Women: Beige Design | Balancing Cold Protection and Style] This is a limited lineup featuring only the pink color, which is particularly popular with women. The simple and elegant pink brightens up dark winter outfits and acts as a fashion accessory for everyday wear while also providing cold protection. The practical and sophisticated design is a great gift for female friends, girlfriends, and family members. [Double-Layer Structure Keeps Ears Warm | For Skiing and Extremely Cold Outdoors] The outer layer is made of tightly woven fabric that shuts out the wind, and the inner layer is a double-layer structure using extremely thick, cloud-like soft fur. It completely blocks the cold air from the outside and prevents the body's internal temperature from escaping. It's a high-performance cold-weather specification that keeps your ears warm even on sub-zero ski slopes or in the face of freezing winds while camping. [Light Blocking & Ear Warmth Support "Sound Sleep During Travel and in the Bedroom"] When worn at bedtime, it effectively blocks light from the sides of the eyes. Furthermore, the warmth that envelops the ears induces relaxation, making it ideal for those who are sensitive to light or who want to get a good night's sleep at home, in hotels, or on public transportation. It's also comfortable to use in conjunction with a mask. [Zero Pressure, Lightweight Design | Comfortable for Long Hours of Wear During Commuting and Work] Made with highly elastic material that fits the head circumference, it's lightweight, so you won't feel much tightness or weight even when wearing it for long periods. It's perfect for "while-doing" cold protection during times when you want to concentrate quietly, such as when working on a PC, reading, or on the commuter train.
