We present some estimates of T-odd fragmentation and distribution functions, H_1^ and f_1T^, evaluated on the basis of a fit on experimental data in p^↑p. Assuming the T-odd fragmentation function to be responsible for the single spin asymmetry in pion production in p^↑p, we find the ratio H_1^/D_1 to be in good agreement with the experimental results from DELPHI data on Z -> 2-jet decay. We use our estimates to make predictions for ep^↑.
