Coolmax fitted sheets actively help regulate your body temperature for a refreshing night's sleep. The sheets are manufactured from pure Coolmax fibres for optimum quality & softness. The Coolmax fibres are especially developed to provide a unique moisture management system. Moisture is transmitted rapidly along cross channel fibres with increased surface area away from the body. Unlike cotton or polyester, this moisture is not absorbed inside the fibre itself, & Coolmax has been proven in tests to have vastly enhanced breathability & faster drying properties. The benefits are not only that perspiration & moisture are actively moved away from your body, your bed linen will also remain fresh & dry throughout the night. The product is non-allergenic, easy to use & to care for.
