GSM (grams per square meter) indicates weight. 120-140 GSM is lightweight and breathable, 150-170 GSM is medium to heavy, ideal for cold sleepers. Higher GSM provides more warmth but can be less breathable.
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 reduces friction.
OEKO-TEX certification ensures no harmful chemicals are used in production. It indicates safer sheets, especially for sensitive skin, but doesn't guarantee softness or durability.
Lightweight flannel (120-140 GSM) with breathable construction can be comfortable in air-conditioned rooms, but most flannel is too warm for hot summer nights without AC.
Brushed cotton is a finish where fibers are raised to create softness. All cotton flannel sheets are brushed to some degree, but higher quality sheets are double-brushed for extra softness and warmth.
