We propose a new method to measure the mass of large-scale filaments ingalaxy redshift surveys. The method is based on the fact that the massper unit length of isothermal filaments depends only on their transversevelocity dispersion. Filaments that lie perpendicular to the line ofsight may therefore have their mass per unit length measured from theirthickness in redshift space. We present preliminary tests of the methodand find that it predicts the mass per unit length of filaments in an
