A pillow filled with 85% goose feather and 15% goose down, giving medium support that yields under the head while still holding its shape through the night. The fill sits in a 233 thread count cotton percale casing that feels smooth and lets air move, which helps the pillow stay comfortable rather than hot. Shake it out each morning to keep the loft even. Most sleepers choose a pair, one to sleep on and one for support.
