While most mattress protectors are water-proof, cutting off all the breathability—our premium Kool-Flow™ Organic Cotton Mattress Protector is micro-vented, offering the best breathability to cycle out body heat and help you get the coolest sleep your mattress can give while staying soft, cozy, and protected.

Kool-Flow™ Organic Cotton is soft, cozy, and effortlessly cool. Infused with 1% Lycra, it's designed to stretch, contour, and hug your body just right—helping you get the most out of your hybrid, memory foam, or pillow-top mattress without the "plastic" feel that firms up the surface like other protectors.

Infused with sustainable Eco Dry technology for a water-resistant surface that protects from sweat, skin oils, and small spills to extend the life of your mattress, help protect your warranty, and keep you sleeping happy without harsh chemicals or plastic backings that sleep hot and feel crunchy. Eco Dry finish is wash-resistant, hypoallergenic, non-toxic, and free of harsh chemicals.

Our Kool-Flow™ Protector uses a stretchable, 100% organic cotton material on the top surface, infused with 1% Lycra to give it that signature contouring stretch property. Total content of materials: 52% Organic Cotton (top surface), 47% Polyester (fitted sides), 1% Lycra (for stretch).

Our protector is made using hypoallergenic, environmentally friendly materials that are safe and non-toxic. Sustainable Eco Dry water-resistant finish is made with eco-friendly materials free of allergens and harsh chemicals such as Fluorine, Fluorocarbons, PFCs, PFAs, PFOS, PFOA, APEO, Formaldehyde, Paraffin, or Halogens.

100% USA made with durable, high-quality materials that are built to last and treated with wash-resistant Eco Dry finish. While you don't need to wash a protector nearly as often as sheets (a few times a year at most is recommended), you can wash your Kool-Flow™ protector on a cold, delicate cycle and dry on low to medium heat.
