Heavy duty, high visibility driver safety gloves are constructed from pigskin leather. The keystone thumb provides added reinforcement and padding where the glove receives the most wear - this thumb style is preferred by most safety and health engineers because it is the most ergonomically correct thumb style available in work gloves. Additional features of this glove include a shirred back, and a color-coded bias tape sewn hem used for ease in sizing identification. Possible usage includes general purpose applications such as construction, transportation, warehouse, iron/steel work, masonry and equipment operators.
