01. ALGO Performance Tee

This is top of the line clothing. Moisture wicking, quick dry, UV protection, even odor suppression. Tough and durable, extremely comfortable, built to last.... I wish it was my size. I have a second shirt from them that is a medium, but they're roughly the same size. They're NOT relaxed fit shirts, so if you want it to be loose, then a size small needs a medium, otherwise, if you're a size small, and you put on a small, it's going to be snug, not too tight, but it'll definitely fit properly.
