A tacky polyurethane coating over a cotton base provides an instantly secure grip. Thin enough to affect grip size only slightly, Ultra Grip is thick enough to add important cushioning and moisture absorption. Ultra Grip is 0.70 mm thick and 110 cm in length, and is sold in packages of two grips.
"Overgrips" are generally not adhesive and are placed on top of the base racquet grip. Easier to install and remove than self-adhesive replacement grips, an old overgrip can quickly be changed between games in a hot match. Black Knight offers four overgrips - Power Wrap, Ultra Grip, Sensa Grip and the classic TUF Grip.
