This feather pillow is filled with 39 OZ of 90% grey goose feather and 10% grey goose down, naturally captured for premium quality. It offers excellent moisture absorption, breathability, and fluffiness, providing cervical vertebra protection and improving sleep quality throughout all four seasons. Meticulously crafted with four layers of fabric, the inner and outer layers are made of durable, polyester fabric. The outer layer acts as a tough shield, being abrasion-resistant and wrinkle-free, while the inner layer with a fine weave prevents feathers from poking through, ensuring a comfortable sleep. It is recommended to tumble dry after washing until the filling is completely dry and follow proper washing and drying instructions for maintenance. To prolong the life of the pillows, a pillow protector is recommended to protect them from stains and dirt.
