10 Best Warm Sheets For Winter 2025 in the United States

The True North by Sleep Philosophy flannel sheet set is made from 100% cotton flannel, which is naturally warm and breathable—ideal for staying cozy during cold winter nights. The brushed flannel weave gives it a soft, fuzzy texture that traps heat well without overheating. This set includes a fitted sheet with an all-elastic pocket that fits mattresses up to 14 inches deep, making it versatile for many bed sizes.
