The BaR-SPOrt experiment, a project to measure the linearly polarised emission at 32 GHz and 90 GHz of 20°×20° sky patches from a stratospheric balloon, is presented. It consists of correlation polarimeters for direct measurements of Q and U Stokes parameters, coupled to off-axis optics providing a beam of 0°.5 - 5°.2. The scientific goals as well as the instrument design are described. Particular emphasis is put on the hardware solutions adopted to reduce the systematics effects in high sensitivity polarisation measurements.
