A wrappable textile sleeve with closure system and method of construction is provided. The sleeve has a wall of interlaced yarn with opposite edges extending in a lengthwise direction along a longitudinal axis between opposite ends. The opposite edges are wrappable into overlapping relation with one another to form a tubular cavity. The wall has a first set of closed loops positioned adjacent one of the opposite edges and a second set of closed loops positioned adjacent the other of the opposite edges. At least one flexible lace is disposed through the closed loops in a zig-zag pattern, thereby extending back-and-forth between the first set of loops and the second set of loops. The flexible lace is slidable through the plurality of loops to facilitate drawing and maintaining the opposite edges in overlapping relation with one another.
