Made with a highly porous foam, this extremely absorbent towel is simply amazing. With just a quick touch this towel absorbs and holds water. Just wring out the towel to start again; you'll be dry faster than you think. When dry, the foam material hardens and becomes stiff. To re-vitalize simply wet the towel and allow a moment for it to absorb the moisture. For best results, store in the plastic case included with purchase.
