You know exactly the type. Either your dad or grandfather wore them to play tennis or to go jogging. When I mentioned a couple of years ago that I think there should be a revival of them, I was strongly discouraged. I thought they would be a good fundraiser for our local JCC, embroidered with their name. But, we didn't have an investor or a plan of how to sell them, so the idea just fizzled out.
And then, boom, they show up on Phish dry goods, embroidered with Phish's name.
I still get the dour remarks, "Loony, no, please, don't do it." "Loony, you will look ridiculous" So, I heed the call of the fashion police and I don't wear them.
On 1st night's show there were a group of teenagers with one of the dads in front of us. It was all their first show. And the son was geared up in full regalia: red & white headband, wristbands, and a red & white t-shirt where the image is of a bass guitar's head in white. I complimented the dad and told him he should be proud of his son. The teen was dressed quite tidily...proper I would even venture to say.
Here's what I have to say about tri-color sweatbands:
The are all the rage.
And when you rage wearing terry headbands at a show, they give you that rock-star-quality aura.
