The "Balance" Gi is a nod to the opposing yet complementary forces of Yin and Yang, designed by the folks at Ground Game.$89
5'11; 215lbs. Will A3 be good after some shrinkage?
Will it shrink when you wash and dry it?
Google BJJ GI size chart. That will explain everything you need to know about height/weight and the right GI size accordingly.
what size for 5'11 and 160 lbs?
A2
5'9 and 215lbs which one
Tough call with this Gi, as your height is an A2 but your weight is more of an A3 or A4. Ideally you would rock one of the Gis that offer "in between" sizes; you're perfect for the A2H (a2-husky) style that's offered by 93 Brand, Flow Kimonos, Inverted Gear, etc. If you want to jump on this Gi, though, you'd need to go up to A3. The sleeves/pants may be a bit long until you shrink-to-fit or take them in a bit.
190cm, 90kg. A3 should be the right size?
Is this gi ibjjf approved?
Yep
Is this gie lighter than fuji
Depends on which Gi you mean, Fuji makes several BJJ Gis. It is lighter than their "All Around" aka "Victory #7000" Series, lighter than their Kassen Series, and the Ground Game jacket is about on par with their Summerweight series, the Ground Game pants are lighter than the Summerweight series.
