Does anyone else think the Jedi robes are a little impractical?

I remember the first time I saw A New Hope thinking Obiwan was wearing an awful lot of layers. There's boots, trousers (at least, I presume; I can't see them), and a belt. So far, so good. But then there's the brown robe, at least one tunic, though I think it's actually two, and then a brown shirt underneath it all.

First of all, that's way too many layers for noon in the desert. Yes, you want to keep the sun and sand out - but the brown shirt and the robe should cover it! Why tunics too?

My confusion grew throughout the Prequel Trilogy. I don't care how in tune with the Force you are: long, multi-layered outfits are just not practical for fighting. Sure, Jedi often went on purely peaceful missions, and in those cases their "simple" (ha! even the queen has less layers sometimes!) attire was probably just fine - but aggressive negotiations seemed far from rare or unexpected, so why hamper themselves so much? Can you imagine how waterlogged Qui Gon and Obiwan must have been after swimming to Otoh Gunga? Can you imagine how much drag those robes would have been exerting as they swam?

And even when they ditch the top robe to fight, they still have the issue of the other three layers. That much fabric restricts your movement. Especially when it's as thick as those tunics appear. I can see the reasoning behind Anakin's leather tunic-thingy (blast damping or something), but he still has too many layers under it. Again - why not just a thick shirt, maybe with a very thin undershirt, with the trousers and robe? If they're going to Hoth, they can bring sweatshirts. Or use the Force.

I decided I was overanalyzing the costumes and tried to forget about it - until I read a quote from either Hayden or Ewan, I can't remember, to the effect of, "The EIII duel was really hard because we kept getting tangled in our robes."

Someone should have told Yoda that if design practical clothing an order cannot, fall it will.

I also noticed that Luke does not choose to don the robes. He sticks to simpler attire. This gives me confidence in his ability to reform the Jedi Order better than it was before
