Atama summer weave might be lighter than those above. Not too sure.
I just got a Sirius Ultra Light gi. It's light although not amazing(I don't have other light gi's so I can't compare), but soft and comfortable, and fit pretty well on me (5'7", 150lbs). Compared to Mizuno Eurocomp judogi, which is like a steel armor, Sirius feels like a sweater. I'm washing it right now to see how it'll change...
