Recently the superconducting gap functions of the skutterudite PrOs4Sb12 have been proposed [K. Maki et al, Europhys. Lett. \bf 68, 720 (2004)]. The superconductivity is spin-triplet and consists of at least 2 distinct phases in a magnetic field, which bears some resemblance to superfluid 3He. Here we present our analysis of the thermodynamic properties of these two superconducting states within the weak-coupling BCS theory. The superfluid density of the B phase is compared with recent experimental data.
