ZEN Comfort sheets are made of advanced poly microfibers. They breathe like athletic apparel, to keep you comfortable all night long. Zen Comfort sheets are hypoallergenic – great for allergies, sensitive skin, and eczema. They are also anti-microbial, to prevent dust and pollen from adhering to fabric and aggravating allergy or skin issues. Zen Comfort sheet fibers are never treated with pesticides, like natural non-organic fabric. Always ultra-soft, right out of the package, the anti-slip, non-sateen finish means they are soft without slipping or sliding off the bed. They get softer with every wash! Zen Comfort sheets are eco-friendly; we love our environment! Our stain-resistant, lightweight, non-shrink, fade-resistant, and wrinkle-free sheets dry in approximately 15 minutes in the dryer. They are cost-effective and energy efficient!
