We study the real triplet model in which the neutral component of the triplet is a dark matter candidate and the charge components are long-lived. The long-lived triplet particles will result in disappearing charged tracks when produced at colliders. Utilizing this disappearing charged track signature from the decay of the charged components, we study exclusion limits from the LHC and a prospective 100TeV $pp$ collider. We also investigate the dark matter candidate and obtain constraints from present and future dark matter direct detection experiments. We conclude that XENON20T could cover almost the entire parameter space of this model except for a vanishingly small portal coupling.
