This is the Waterproof Pillow Case from B Sensible. This pillow case is both breathable and waterproof, giving you a comfortable place to rest your head whilst you sleep. The high quality Tencel fibre ensures a soft finish and being breathable helps it to reduce the build up of moisture and humidity. The stretchable membrane not only protects your bedding but also provides a barrier against mites and bacteria. To allow cleaning without any fuss the case is fine for machine washing and tumble drying.
