The present invention relates to a spacer fabric with advanced cushionability, flexibility, and thermal conductivity, and a method of fabricating the same. The white light may have a color rendering index of 100 and may be produced with an efficiency of at least 30 lmw. In the open position the opening exposes the nozzle and in the closed position the nozzle is covered. Still further, the vent body includes a pair of longitudinally-extending sidewalls that project from the outer edges of each of the grillwork walls and that are disposed upright with respect to the upper wall. The destination member can then multicast a recall packet to the members of the multicast group when the destination member determines that the source member claims an identity of the respective destination member.
