Lagostina Hotel-Clad 12pc 5 ply stainless steel cookware set - $199
it consist of 5 layers of metal (same combination as zwilling sensation/Demeyere):
the middle layer is an aluminum alloy, more rigid than pure aluminum but slower heat transfer. you could think of it as a tri-ply but with a really thick aluminum sandwich. I compared it to the zwilling Sol II sigma ply next to it and it is definitely thicker/heavier.
the only thing missing from it is flared lips and etched measurements inside the vessels. none the less, it still seems like a great cookware deal this boxing day.
