Just the fitted sheet — copper-infused bamboo viscose that sleeps cooler than cotton and helps the fabric resist odor-causing bacteria, so it stays fresher between washes. Sold à la carte in your exact size — the perfect replacement when your set's fitted sheet wears out first. What makes it different Sleeps cooler than cotton — Breathable bamboo viscose wicks heat and moisture away from your body all night, so the bed stays cool instead of trapping warmth. Stays fresher between washes — Copper threads are woven directly into the fabric — not a coating — and help it resist odor-causing bacteria, so your sheets smell and feel cleaner longer. Silky-soft, gets softer with every wash — A smooth bamboo viscose weave that feels gentle against skin, and only improves over time. Naturally hypoallergenic — Gentle on sensitive skin and resistant to common allergens. Built for a perfect fit — Deep pocket with 360° elastic and reinforced corner straps grip mattresses up to 18″ deep, including pillow-tops and adjustable bases. Materials 80% Copper-Infused Viscose from Bamboo, 20% Polyester — 330 Thread Count.
