SINGLE-PLY WEAVE: We use only single-ply cotton fabrics that are 100% genuine long fibre cotton yarn. Single-ply yarn is made using one long-staple cotton fibre to create a thread. 300 Thread Count is the perfect thread count for Percale sheets, It is tightly woven enough to ensure premium durability while make sure the sheets are extremely breathable and cool to the touch to give a good and cool sleep. Trust us, this set is so durable that it will last for years. COOLING: The percale weave is breathable, feels soft against the skin and gives the sheets a lightweight feel and a more structured appearance than sheets with a sateen weave. Our organic percale sheets tent away from the skin to allow for better air circulation and a refreshingly cool performance. People who tend to sweat or run hot at night will appreciate the airy quality of these sheets. DOZ by SIJO COTTON PILLOWCASE: SIJO is a bedding brand expertly crafted from innovative materials.
