Each piece in this set contains a thick core of quick-heating aluminum, a non-reactive stainless-steel surface, and is remarkably lighter that other clad metal cookware. The set includes a 1.5-quart covered saucepan, a 3-quart covered saucepan, an 8-quart covered stockpot, an 8-inch open skillet, a 10-inch open skillet, and a 3-quart covered sauté pan with helper handle.
