Our Stackers top hats are tapered so they stack, but they don’t stick together. Since they stack, they take up very little space on the shelf or in the truck. We got the idea from lighting designer Mike Baldassari who needed a way to conserve shipping space on a European tour. Stackers perform exactly like a standard top hat but store in a tiny fraction of the space. The interior of Stackers is flocked to reduce light reflection.
