These deluxe lineman gloves are made with select heavyweight 3-1/2 oz grain horsehide leather, that has been treated with Water stop™ a fluoro-chemical water-repellent emulsion for excellent water, oil and stain-repellent properties. (The soft, breathable qualities of the leather are not affected by this water-repellent treatment.) Other special features include our performance thumb/palm patch, which reinforces critical-wear areas with a double layer of leather. Sewn across the back of the leather cuffs are heavy-duty high-viz fluorescent-yellow fabric strips and retro-reflective silver strips for greater night-time visibility. All styles are sewn with Kevlar® thread for extra seam strength.
