From what I can make out: the Chevron logo (featured image) WAS designed by Jim Labadini, given how many sources cite this as fact; the circle logo (above) I can’t currently trace any facts, neither can I with the logotype version (below) currently used to brand their website. It has the Converse star tucked away in the ‘O’, but you’ll also see variations of this design, notably pulling out the round cornered black square with white star.
