I do sometimes wonder about those fastex buckles, though... they're part of the leg loop. Are they rated? How do they get away with a plastic buckle on a load-bearing part of the harness?
This mystified me the first time I saw it, too. I don't own a harness with fastex buckles on the leg loops, but I think the answer is that all such harnesses have the leg loop webbing that continues up to the waist belt on the outer side, like a BD Bod or Alpine Bod, rather than a separate leg loop not sewn to the waist belt. In a fall the weight is borne on a loop of webbing that goes down from the waist belt, around the backs of both thighs, and through the lower tie in point. Like a Swiss Seat, not that I've ever used a Swiss Seat either. IOW, the fastex buckles aren't fall-bearing, they just keep the harness from coming off. That is my rationalization.
