[@DarkFey] - This is part of our write up on Quarian's on the first page. Envirosuits are still very much required at the moment, though they wont be soon. Personally I like the thought of the Quarian's adopting them as cultural garb though, even when they no longer need them. 

[quote] With Quarian know-how and Geth assistance, development was efficient and careful; and the first colonies are being erected on Rannoch. Though their immune systems are still incredibly weak, Geth reprogramming of environmental suits has helped immeasurably and many predict that the next generation of Quarians will be able to travel the galaxy unmasked.[/quote]
