We investigate disorder-induced localization in metals that breaktime-reversal and inversion symmetries through their energy dispersion,$\epsilon_{k}\neq\epsilon_{-k}$, but lack Berry phases. In the perturbativeregime of disorder, we show that weak localization is suppressed due to amismatch of the Fermi velocities of left and right movers. To substantiate thisanalytical result, we perform quench numerics on chains shorter than theAnderson localization length -- the latter computed and verified to be finiteusing the recursive Green's function method -- and find a sharp rise in thesaturation value of the participation ratio due to band asymmetry, indicating atendency to delocalize. Interestingly, for weak disorder strength $\eta$, wesee a better fit to the scaling behavior $\xi\propto1/\eta^{2}$ for asymmetricbands than conventional symmetric ones.
