We study topological open string amplitudes on orientifolds without fixedplanes. We determine the contributions of the untwisted and twisted sectors aswell as the BPS structure of the amplitudes. We illustrate our general resultsin various examples involving D-branes in toric orientifolds. We perform thecomputations by using both the topological vertex and unoriented localization.We also present an application of our results to the BPS structure of thecoloured Kauffman polynomial of knots.Comment: 43 pages, 8 figure
