The Calvire Supima Cotton Sheet Set makes the bed feel instantly more polished, with a smooth, graceful drape and a soft sheen that settles against the skin with a cool, silky feel. Made from 100% authentic Supima extra-long staple cotton grown in the USA, the set is crafted in a 600 thread count satin weave for an exceptionally soft, smooth, lustrous finish. The longer fibers give the fabric strength, durability, and excellent resistance to pilling, while the weave stays breathable and temperature-balancing through every season. Tailored flange details frame the bedding with a clean, refined finish, and precise stitching gives the set a hotel-inspired, quietly elevated look. Each Calvire Supima Cotton Sheet Set includes four pieces, one flat sheet, one fitted sheet, and two pillowcases, for a complete bed that feels beautifully put together.
