The classical double bubble theorem characterizes the minimizing partitions of R-n into three chambers, two of which have prescribed finite volume. In this paper we prove a variant of the double bubble theorem in which two of the chambers have infinite volume. Such a configuration is an example of a (1,2)-cluster, or a partition of R-n into three chambers, two of which have infinite volume and only one of which has finite volume. A (1,2)-cluster is locally minimizing with respect to a family of weights & sup1;cjk degrees if for any Br.0/, it minimizes the interfacial energy Sigma(j= 8 under anatural growth assumption. We also obtain a closure theorem for locally minimizing (N,2) -clusters
