HyperDrii is a revolutionary "hyperventilation" mat designed for marine and recreational travel uses, such as boats, cabins and RV's. It has been engineered to improve air circulation in any environment, including those that are poorly ventilated or filled with excess moisture.

Hyperdrii is a revolutionary solution, similar to Hypervent mattress underlay, that protects mattresses and cushions from moisture.
