  We present a model for the remnants of haloes that have gone through an
adiabatic tidal stripping process. We show that this model exactly reproduces
the remnant of an NFW halo that is exposed to a slowly increasing isotropic
tidal field and approximately for an anisotropic tidal field. The model can be
used to predict the asymptotic mass loss limit for orbiting subhaloes, solely
as a function of the initial structure of the subhalo and the value of the
tidal field at pericentre. Predictions can easily be made for differently
concentrated host-haloes with and without baryonic components, which differ
most notably in their relation between pericentre radius and tidal field. The
model correctly predicts several empirically measured relations such as the
`tidal track' and the `orbital frequency relation' that was reported by Errani
& Navarro (2021) for the case of an isothermal sphere. Further, we propose
applications of the `structure-tide' degeneracy which implies that increasing
the concentration of a subhalo has exactly the same impact on tidal stripping
as reducing the amplitude of the tidal field. Beyond this, we find that simple
relations hold for the bound mass, truncation radius, WIMP annihilation
luminosity and tidal ratio of tidally stripped NFW haloes in relation to
quantities measured at the radius of maximum circular velocity. Finally, we
note that NFW haloes cannot be completely disrupted when exposed adiabatically
to tidal fields of arbitrary magnitudes. We provide an open-source
implementation of our model and suggest that it can be used to improve
predictions of dark matter annihilation.
