Maoz

The bread they use for their wraps is very thin and very strong. Good tensile strength. Flexural strength is also great, but that's kind of a given. When you're running with a falafel wrap, material science is very important. A falafel wrap carried baton-like through central London undergoes various stresses, all sorts of bumps, jumps, zigs and zags. Structural integrity matters a lot, and on structural integrity, Maoz delivers. Five stars.
