  We study CP sensitive observables in chargino production in electron-positron
collisions with subsequent two-body decay of one chargino into a W boson. We
identify the CP odd elements of the W boson density matrix and propose CP
sensitive triple-product asymmetries of the chargino decay products. We
calculate the density-matrix elements, the CP asymmetries and the cross
sections in the Minimal Supersymmetric Standard Model with complex parameters
\mu and M_1 for an e+ e- linear collider with \sqrt{s} = 800 GeV and
longitudinally polarized beams. The asymmetries can reach 7% and we discuss the
feasibility of measuring these asymmetries.
