The shopping experience with Kosa was just as good as the product itself. The whole process was seamless from start to finish, super easy to order, and shipping was really fast.

Everything arrived quickly and exactly as expected. No issues at all. Would definitely shop with them again!

Great for Travel

Used this on a 14-hour flight. Completely blocked out the cabin lights. Best sleep I've ever had on a plane.

Better than silk.

I used to use Dore & Rose, but the foam in this is much more breathable and doesn't slip off during the night.
