I'd love to give the Jumpsuit more love, but isn't it way too obviously military? With X-Com insignia to boot?
Besides, it would destroy the "badass in suits" effect in some other missions.
There could be a variant of the jumpsuit with the patches removed, that triggers in infiltrations like camo patterns in different environments. If you want to keep suits, there could be an option for Durathread suits. It's just that I feel like enemies are always popping out from unexpected spots and getting in potshots that cripple or kill my agents. It's possible I'm just used to Piratez, since the gals are a bit hardier than agents.
