  This paper introduces two constructions of Legendrian submanifolds, called
the Legendrian product and spinning, and computes their classical invariants,
the Thurston-Bennequin invariant and the Maslov class, in R^{2n+1}. These
constructions take two Legendrians K,L and returns a product K x L, they
generalize other previous constructions in contact topology, such as
frontspinning and hypercube tori, and are equivalent in R^{2n+1}.
Interestingly, this construction relies upon the explicit embeddings of K,L and
not their Legendrian isotopy classes.
