We present a simple model of the NN-bar imaginary optical potential at low energies based on the bag model of hadrons. NN-bar annihilation is assumed to proceed via qq-bar annihilation in the region where the nucleon and antinucleon bags overlap. This potential depends parametrically on the bag radius R, and so may be fitted to scattering data to yield information about R. Implications for NN-bar bound states (''baryonia'') are discussed.
