Cotton Sateen BETTER PROTECTION - Safely and securely protect your pillows from dust, allergens, dirt, and particles with this luxury 500 thread count 100% cotton sateen pillowcase cover. Our tightly woven design helps keep dirt and debris from penetrating into your pillow. MORE COMFORTABLE - Because we use a super high 500 thread count, our premium pillowcase protectors are softer and smoother than polyester or a lower thread count zippered pillow. Perfect for adding a layer of comfort to pillows of any fill or shell material. MOISTURE WICKING - Our all-natural pillow cover cotton fibers help wick moisture and heat away from your pillow during the hot summer months. During colder months, the cotton sateen helps retain heat to keep your head cozy and comfortable. DURABLE DESIGN - Each signature Lincove lavender-edged pillow protector with zipper is reinforced with durable double-stitched edges and an easy glide zipper that helps lock out allergy debris, dust, and dirt from your pillow. Helping to keep it fresh, comfortable, and clean. CUSTOMER SATISFACTION: If you aren’t satisfied with our Lincove product, please let us know.
