the XS has big arms and tiny torso if you want it tight. the S seems to have same arms and bigger torso. material is great, durable, wicking, cooler than cotton and breathes nicely even tho it seems like you're wearing a plastic bag at first. this is my first time wearing non-cotton tops for exercise, and it's so much better in the heat. well worth the sub $10 price.
