We study the vacuum properties of hybrids by using the so-called extended Linear Sigma Model (eLSM). This model includes scalar and pseudoscalar mesons, as well as vector and axial-vector mesons. We enlarge the eLSM by including the low-lying hybrid nonet with exotic quantum numbers $J^{P C} = 1^{−+}$ and the nonet of their chiral partners with $J^{P C} = 1^{+−}$ to a global $U(3)_r\times U(3)_l$ chiral symmetry. Then, we predict the hybrid nonets masses and their decay ratios that may guide ongoing and upcoming experiments
