Yes, flannel is brushed for extra warmth, making it ideal for cold climates. The warmth level also depends on fabric weight (GSM); higher GSM means thicker and warmer sheets.
Wash in cold water on a gentle cycle and tumble dry on low. Avoid fabric softeners as they can break down fibers. Turning sheets inside out before washing can also reduce friction.
100% cotton flannel is more breathable and softens over time, but may shrink. Polyester blends are more durable and wrinkle-resistant, but less breathable. Choose based on your priorities for breathability vs. easy care.
