The 5.3 Dri-Tec performance mattress protector's enhanced honeycomb structure allows for enhanced airflow and heat dissipation to regulate your body temperature for maximum comfort and recovery. It not only protects your mattress from stains and fluids but the dri-tec fabric surface wicks away heat and moisture to keep you cool and dry while you sleep. The soft and flexible surface dynamically reacts with your motion while the breathable, invisible waterproof barrier won’t affect the feel of your mattress. Enhanced airflow improves temperature regulation so you sleep better. Features full-banded elastic to ensure a secure fit and grip that holds tight on all mattress heights, with no baggy sides or bunching. Fits mattresses up to 22" deep. Reduces allergens, blocks pet dander, and dust mites.
