  We extend the Standard Model with an EW fermion triplet, stable thanks to one
of the accidental symmetries already present in the theory. On top of being a
potential Dark Matter candidate, additional motivations for this new state are
the stability of the vacuum, the fact it does not introduce a large fine-tuning
in the Higgs mass, and that it helps with gauge coupling unification. We
perform an analysis of the reach for such a particle at the high-luminosity
LHC, and at a futuristic 100 TeV pp collider. We do so for the monojet,
monophoton, vector boson fusion and disappearing tracks channels. At 100 TeV,
disappearing tracks will likely probe the mass region of 3 TeV, relevant for
thermally produced Dark Matter. The reach of the other channels is found to
extend up to ~ 1.3 (1.7) TeV for 3 (30) ab^-1 of integrated luminosity,
provided systematics are well under control. This model also constitutes a
benchmark of a typical WIMP Dark Matter candidate, and its phenomenology
reproduces that of various models of Supersymmetry featuring a pure Wino as the
lightest sparticle.
