a class of ISS GUTs where the only scale below the cutoff is that of supersymmetry breaking. The model presented here differs from the one in Ref. [@Hall:2013eko] in that the mass of the whole $H({\bf 5}) 
+ \bar{H}({\bf 5}^*)$ Higgs fields, of which the SM Higgs field is a part, now arises from supersymmetry breaking, where the numbers in parentheses denote representations under the $SU(5)$ GUT group. This is achieved in a simple manner by obtaining the whole Higgs potential, including the one associated with the GUT-breaking field $\Sigma({\bf 24})$, from the Kähler potential. We first describe the model and spectrum, discussing if/when the wino mass is lowered to the TeV scale due to a cancellation among various contributions as a result of environmental selection associated with the dark matter abundance. We then discuss gauge coupling unification and proton decay. We also present a detailed phenomenological analysis of the model in the case that the supersymmetry breaking parameters obey the mSUGRA-like boundary conditions at the supersymmetry breaking mediation scale $M_*$.

We consider that physics below the cutoff scale $\Lambda \sim M_{\rm Pl}$ is well described by a supersymmetric GUT with the same field content as the
