In a protective glove, such as a firefighter's or welder's glove, which has a main portion, a thumb-covering portion, and four finger-covering portions and in which each portion has a front face and a back face and each face having a periphery, an edge strip joining the peripheries of the front and back faces of the of the main, thumb, and finger portions has two elongate edges, which are equidistant when the edge strip is taut, except in specific regions, where the protective glove when worn covers the wearer's knuckles and where the protective glove when worn covers the heel of the wearer's hand, at which regions the edge strip is widened to facilitate flexing without binding. Preferably, those regions where the edge strip is widened are located along a single one of the elongate edges, namely, the elongate edge joined to the peripheries of the back faces of the main, thumb, and finger portions.
