Naruto Sasuke's Costume

Would anyone know what's the name of the things on Sasuke's arm?

 

I think they are arm bracers. Or maybe they are just for decoration, I can't remember if he ever used them in a battle or not.

 

Stupid Question, which costume? His old one or is current one?

 

current one(i think)

 

If it's the current one, the bandages aren't just for cool looks, they are also are used to bind down the enemy while performing a technique. Take Lee's secondary Lotus for example.

 

i dont know if sasuke's do, but many bracers have iron bars under them for blocking blades or to cause damage when blocking arms/legs. anyway, they are bracers.
