4-mil thick, strong enough for working with tools and machinery. You can safely wear them for longer durations, and they offer an excellent barrier against paint, varnishes, cleaning solutions, and a wide range of chemicals. A micro-roughened surface and textured fingertips make for a solid grip that won't slip, even when they're wet. Powder-free, no messy residue, and latex-free, so no worries about aggravating latex sensitivities.
