The English word "pierogi" comes from Polish pierogi, which is the plural form of pieróg, a generic term for filled dumplings.
A regional favorite here in Pennsylvania, we figured there wasn't a better name for a bar bag that's going to be stuffed with all sorts of goodness. The shape might not be a dead ringer for the doughy delights, but is pretty close, and perhaps a little more aero.
These bags work well on drop bars, flat bars, and even a number of alt bars like the Jones and Surly Moloko. On the Jones it actually allows for use inside the Loop!
