- Extremely durable microfilament fabric with NEW double lock zipper
- Wash & Dry Unlimited ,10-Year Warranty
- Average width of the microscopic fiber pores is under 5 microns
- Made with Evolon® fabric, a perfect protective layer against dust mite allergens
- Evolon®’s filtration ability is due to the dense, compact structure of tightly entangled microfilaments. The very small dust mite allergen parts are retained under the
- Evolon® layer, and cannot get in contact with the allergy sufferer. No "plastic” coating, no additional chemical treatment is needed to achieve this protection.
