For Christmas, Tea Time got me a black Nike tank top (size S). I am generally not adorned with Nike anything, simply due to cost.
Although I was thrilled with it, I didn't wear it too often because I generally don't wear sleeves things in general because I have some sort of self-consciousness/borderline psychological disillusionment with my arms. The tank itself if great, though. It has a shelf bra and padding, which is always welcome.
The tank itself feels snug, which is more than what I'm used to, but then again, I used to run in men's boxers (did I just admit that online?). I like the black color because it conceals sweat, and the material is good for running for the most part.
As you can see in my mud run post, I took full advantage of it, and yes, it's still in workable condition after a good wash.
I kind of want to get more of these, but I'll have to see how often I can commit to sleeveless anything. I have to admit that wearing race T's all the time is not the sexiest...
