Polyester fiberfill having spiral-crimp, especially in the form of an omega (.OMEGA.), that is randomly-arranged and entangled in the form of fiberballs with a minimum of hairs extending from their surface, and having a refluffable characteristic similar to that of down on account of the low cohesion between the balls. A process for making such fiberballs by repeatedly air-tumbling small tufts of such fiberfill against the wall of a vessel.
