why do boxers wear a band on arm near shoulder?

what is it? from matt blake

Can you show us a picture of that, Matt? Muay Thai fighters wear Pra Jiad on both their arms, which I believe is for traditional, mystical reasons. I've never heard of Western boxers doing anything like that.

it just makes your bicep look bigger, try it yourself and see. it's nothing.

i do not have a photo i wsh someone did

i wish we could wear them in summer when we wear tee shirts and gi pants
