Cotton Percale is a classic weave that is naturally lightweight, cool, crisp and breathable, perfect for those who tend to sleep hot or live in warmer climates. Our sheet and duvet sets are also pre-washed, which adds softness to the fabric and creates a comfortable lived-in feel with the very first use. Pair the sheets with our matching duvet for a coordinating look in your restful retreat. They are machine washable for easy cleaning, and be sure to read our wash care tips to ensure you get the best out of these time and time again. You can be confident in your purchase as these sets are certified STANDARD 100 by OEKO-TEX®, meaning they have been independently tested for harmful substances according to strict scientific criteria that go beyond global legal regulations
