We present QCD prediction of double-spin asymmetries (ATT) in transversely polarized Drell-Yan process at small transverse momentum QT of dimuon. Resummation of large logarithmic corrections, relevant in small QT region, is performed up to next-to-leading logarithmic (NLL) accuracy. ATT at RHIC, J-PARC and GSI are studied numerically in the corresponding kinematic regions. We show that the large ATT is obtained for small QT and moderate energies.
