Air Dry keeps the windows clear - especially during the wet season. Air Dry has been specifically designed for use in vehicles. It attracts moisture from the air like a magnet. Its subtle, anthracite-black, slim cushion shape blends perfectly into the interior design. The natural storage granulate is particularly absorbent. The bag consists of a non-woven top side that becomes noticeably damp and a foil underside that prevents moisture transfer downwards.
