[Star Wars] Why don't more Jedi wear armor in battle?

I mean robes are really stylish, and traditional, but there have been times in the galaxy when the Jedi are forced to go to war. Why don't more of them opt for armor, especially the lightweight variety that does not hinder their movement or agility while providing protection against explosions and blaster fire?

I noticed that Obi Wan once wore modified clone trooper armor in one battle in the Clone Wars, but why didn't more choose this option?

Some did, especially during the Clone Wars, but you gotta remember that Jedi are primarily peacekeepers, and aren't warriors. Their primary purpose when traveling to a conflict is to defuse that situation. Showing up in full battle rattle isn't a great way to convey peaceful intentions (even if it might seem most practical at the time), and honestly, the Jedi have little need of it. Most situations they get into can be resolved through negotiation, the Force, or a lightsaber. The only time it would really be practical is when they are in a serious war zone where they are constantly under attack from numerous types of threats, like shrapnel, where armor would be most prudent, and even then many don't wear it out of preference. 

So, in reality, there's no real need for them to do so outside of extreme circumstances, unless they want to.
