Gloves are sold by the handedness of the shooter. So a right-handed shooter, requiring a glove for their left supporting hand, should select Right-Handed. A left-handed shooter, requiring a glove for their right supporting hand, should select Left-Handed.
Kurt Thune gloves are made out of real leather and Clarino®, which is a space-age synthetic leather that is stronger and breathes better than natural leather. The lining is 100% cotton, and all seams are formed to avoid pressure points.
The Solid-Grip glove provides a combination of these features, with stiff white rubber on the outside of the hand to provide support in all three positions, with top-grip on the inside of the hand to provide comfort and grip.
