The "Shur-Grip" is a seamless rubber tube that rolls onto your longbow (and some recurves) and stretches to fit the curves of the grip like a skintight glove. These grips offer solid non-slip positioning in the hand, they're impervious to water or snow, they're easy to install, and they're reasonably priced. (A trick to installing these on recurves with a little more mass on the riser is to roll them up like a doughnut and over a short piece of parachute cord. Then when you get to the largest section of the riser, you can use the rope like a flexible lever and force the "Shur-Grip" up and over the largest section of the riser.)
