This is a light blue and navy short sleeve shirt top.
It is made of a thin fabric, 100% polyester. This is the one that catches easily. You have to be very careful with it. The threading is white.
I had assumed that this was a womens shirt but it is only a size XS and it’s quite roomy. But I’m not sure if the sleeves are long enough to be a mens shirt. As you can see from the label, it was made in Vancouver.
There is the small pocket on the side. This pocket has a double layered top. There is no hole for ear phones so maybe it’s just for a card or key?
The silver omega symbol is on both sleeves and on the back. This is the larger symbol.
