## Description

Alaska Bear - Enhance your Life You won't believe how smooth it feels! Our natural silk sleep masks not only feel smooth against your skin but are also hypoallergenic, great for those with sensitive skin. Mulberry silk is the fabric of the emperors. It is the most elegant of all the silks with a luminous sheen and a smooth touch. Buy for yourself or as a gift or consider it an investment in your travel accessories. Everyone will love the beauty and SIMPLE COMFORT of this silk. Three versions available: 1)One strap version 2)Two straps version 3)Nose baffle version Why using a sleep mask? The hormone Melatonin regulates the day-night cycle of the human body and controls the recovery phases during the sleep. For the production of this hormone, the human body requires sufficient darkness. Lightness prevents the production of Melatonin. Even a little light caused, for example, by a digital alarm clock can be a disturbance. The best sleeping mask however will naturally help you increase melatonin levels and increase REM sleep. Sleep masks- what for? - if your bedroom cannot completely be shaded by black-out curtains and you want to sleep in - if you cannot fall asleep because your partner wants to read or watch TV - if you want to sleep while travelling, e.g. on airplanes or in trains - if you are looking for perfect relaxation during yoga, wellness or meditation

Review: High quality - Very comfortable for both back and side sleepers. No eye pressure. It's not hot and huge. Sticks in place. Nothing more to wish👌
Review: This product is wayy over rated. - It doesn't fit my face at all, the nose curve is way too big for my nose and lets in excess light. - It's too bulky and heavy, I can't sleep on my side without feeling the bulk. - The bump feels super tight and suffocating around the eyes, if I loosen it, it lets in more light... - I woke up with dryer skin than usual, feels like the fabric absorbed in all the moisture in my skin.

## Questions & Answers

**Q: Is it hot to wear**
A: My girlfriend and I each have one of these, and she is always overheated (to the point where I sleep with extra blankets to keep the room cold enough for her), and she's never said anything about the mask being hot. I also have never felt it to be hot to wear. It manages to cover the eyes well, while leaving the nose capable of breathing.

**Q: Is the contoured cups mask made of silk?**
A: we offer the silk version w contour on amazon, just search this ASIN: B09QBTQGP5

**Q: does this eye mask rub against your eye lashes? i have always used contour ones to avoid this...**
A: No, I do not feel any pressure on the eyes and I have long lashes. And if it does, the mask is so soft it doesn't irritate the lashes or anything else on your face. I hope this is helpful.

**Q: How do you use nose baffle? Lay on nose or fold under mask?**
A: I tried folding it under but I'm a restless sleeper and it never stayed put. I finally put a thin line of fabric glue on the outside edge, away from my face, and folded the baffle up and held it in place until the glue dried. It's better.

### ⭐⭐⭐⭐ Review
*by E***T on 15 June 2023*

I ordered 2 masks, one for my partner and one for myself. The mask I bought for myself had the stars on it and my partner had this full black mask. When they arrived they were both quite different. The totally black mask had a larger eye coverage area, the area around the nose had more material to help block out the light, the contour parts were softer and the bag that came with it was a larger black silk bag (the stars mask included a very small organza big which was definitely not big enough. I reached out to customer service to state the the mask with the stars was not as good quality and I asked if they could send another black mask. They did this without any issues and it arrived very quickly! So for that they are a great company. I do not go to sleep with my mask on, but with the current very hot weather, the open windows mean I get waken up by the birds in the very early morning. I then know it's about to get very sunny so I put on the mask. It's very comfortable and the coverage across the eyes is great! I do often sleep on my side so on occasion the nose coverage part is pushed over and it does let a bit of light in, but I just re-adjust and it's not an issue anymore. I am definitely happy with my purchase and it's been vital in letting me get back to sleep when the sun beams into the room at 4am.
