A Quicksilver t-shirt I got about 18 years ago. It's been my 'haircut t-shirt' for a long time now, though. It used to bother me how after having my hair cut and washing the t-shirt I was wearing, there were usually still hairs in the neckline, making me itch. So I retired that old t-shirt and now exclusively wear it for hair cuts, and my other t-shirts remain itch free. It's lasted so long because I only get my hair cut a few times a year.
