Abstract: A product including two or more plies with each ply including one absorbent layer and a second opposing fluid impervious layer. The two plies are arranged such that the fluid impervious layers face each other and are positioned at the inside of the two-ply product. The two plies are bonded on two or three sides to form a sleeve or a pocket, such that a hand can be inserted between the two plies and positioned in contact with one or both fluid impervious layers. In this manner, the product is absorbent on both sides, and can be utilized on both sides while preventing hand contact with the material absorbed or picked up by the product.
