OE Tech is mostly rebrands of CONDOR and UTG stuff.
Generally CONDOR is "okay" while UTG is crap.
600D is okay for low wear stuff, like a hydration pouch, for example. But I'd stick to 1000D for actual vests and heavy wear items (holsters, mag pouches), unless you're a very "stand around, don't get dirty" kinda player.
Check out PANTAC's stuff, it's all 1000D and the quality is about on par with Blackhawk which is good for airsoft.
