This twin-size linen sheet set is crafted from European flax for a breathable, luxurious feel. The deep-pocket fitted sheet accommodates mattresses up to 15 inches thick, staying securely in place with 360-degree elastic all around. Linen naturally wicks moisture and regulates temperature, keeping you comfortable in both warm and cool weather. The set includes a fitted sheet, flat sheet, and one standard pillowcase. OEKO-TEX Standard 100 certified to be free of harmful chemicals, these sheets become softer with each wash while remaining strong and durable.
