Soft and supportive, the Casper pillow delivers cloud-like plushness within a balanced design. Each cluster of down-alternative fibers is individually blown into the cover to prevent clumping and retain bounce with a quick fluff. With an inner and outer pillow, its structure includes a two-inch gusset along the sides for better neck alignment and distribution. The pure cotton cover features a percale weave which increases airflow for a breathable, cool touch that lasts. 1 Year Limited Warranty
