1. A unitary nozzle body suitable for attachment to a riser of an irrigation device, the nozzle body comprising a top, an outer skirt depending from the top, an inner skirt spaced inwardly from the outer skirt, and at least one orifice in the outer skirt dimensioned for discharging a stream of water
1. A unitary nozzle body suitable for attachment to a riser of an irrigation device, the nozzle body comprising a top, an outer skirt depending from the top, an inner skirt spaced inwardly from the outer skirt, and at least one orifice in the outer skirt dimensioned for discharging a stream of water, the outer skirt being configured to permit the nozzle body to be removably attached to a riser of an irrigation device, wherein the inner skirt has at least one opening through which water can pass to a region below the at least one orifice and between the inner skirt and the outer skirt before exiting through the at least one orifice. 2. A unitary nozzle body suitable for attachment to a riser of an irrigation device, the nozzle body comprising a top, an outer skirt depending from the top, an inner skirt spaced inwardly from the outer skirt, and at least one orifice in the outer skirt dimensioned for discharging a stream of water, the outer skirt being configured to permit the nozzle body to be removably attached to a riser of an irrigation device, wherein the inner skirt has at least one opening through which water can pass to a region between the inner skirt and the outer skirt before exiting through the at least one orifice, and wherein the opening of the inner skirt is a slot that extends to a free end of the inner skirt. 3. The unitary nozzle body of claim 2, wherein the nozzle body is configured for irrigating about 90 degrees, having one slot formed in the inner skirt and three orifices. 4. A unitary nozzle body suitable for attachment to a riser of an irrigation device, the nozzle body comprising a top, an outer skirt depending from the top, an inner skirt spaced inwardly from the outer skirt, and at least one orifice in the outer skirt dimensioned for discharging a stream of water, the outer skirt being configured to permit the nozzle body to be removably attached to a riser of an irrigation device, wherein the inner skirt has at least one opening through which water can pass to a region between the inner skirt and the outer skirt before exiting through the at least one orifice, and wherein an intermediate skirt is positioned between the inner skirt and the outer skirt and has a length selected to provide, in use, a circuitous flow path between the at least one opening and the at least one orifice. 5. The unitary nozzle body of claim 4, wherein the intermediate skirt has a length greater than a length of the inner skirt. 6. The unitary nozzle body of claim 5, wherein the intermediate skirt has a length less than a length of the outer skirt. 7. The unitary nozzle body of claim 4, in combination with an irrigation device having a riser with an open end with inner and outer tubular walls, wherein, when mounted on the riser: a free end of the inner skirt opposite the top is disposed within the open end of the riser to a depth such that the at least one opening is positioned to permit water exiting the riser into a region within the inner skirt to exit from the region within the inner skirt through the at least one opening; anda free end of the intermediate skirt opposite the top is disposed between the inner and outer tubular walls of the riser such that a flow path between the at least slot and the at least one orifice extends around the free end of the intermediate skirt. 8. The unitary nozzle body of claim 4, in combination with an irrigation device having a riser with an open end with inner and outer tubular walls, wherein, when mounted on the riser: a free end of the inner skirt opposite the top is disposed within the open end of the riser to a depth such that the at least one opening is positioned to permit water exiting the riser into a region within the inner skirt to exit from the region within the inner skirt through the at least one opening;a free end of the intermediate skirt opposite the top is disposed between the inner and outer tubular walls of the riser such that a flow path between the at least slot and the at least one orifice extends around the free end of the intermediate skirt; andthe outer skirt is disposed about the outer tubular wall of the riser. 9. A unitary nozzle body suitable for attachment to a riser of an irrigation device, the nozzle body comprising a top, an outer skirt depending from the top, an inner skirt spaced inwardly from the outer skirt, and at least one orifice in the outer skirt dimensioned for discharging a stream of water, the outer skirt being configured to permit the nozzle body to be removably attached to a riser of an irrigation device, wherein the inner skirt has at least one opening through which water can pass to a region between the inner skirt and the outer skirt before exiting through the at least one orifice, and wherein the top has a flange extending outwardly beyond the outer skirt, the flange having a plurality of teeth separated by gaps, at least one of the gaps being adjacent one of the orifices and the one of the orifices extends through at least the top of the nozzle body in a gap between adjacent teeth. 10. A unitary nozzle body suitable for attachment to a riser of an irrigation device, the nozzle body comprising a top, an outer skirt depending from the top, an inner skirt spaced inwardly from the outer skirt, and at least one orifice in the outer skirt dimensioned for discharging a stream of water, the outer skirt being configured to permit the nozzle body to be removably attached to a riser of an irrigation device, wherein the inner skirt has at least one opening through which water can pass to a region between the inner skirt and the outer skirt before exiting through the at least one orifice, in combination with an irrigation device having a riser with a tubular open end, wherein, when mounted on the riser, a free end of the inner skirt opposite the top is disposed within the open end of the riser to a depth such that the at least one opening is positioned to permit water exiting the riser into a region within the inner skirt to exit from the region within the inner skirt through the at least one opening.
