I commute to work by bicycle (errr ... obviously) and my office doesn't require us to dress up, so I tend to just wear a pair of loose fitting jeans and a plain t-shirt (usually black). I like this because I don't have to carry a bag with spare clothes or anything, I just roll up my jeans before I get on my bike, and roll them down when I'm done. If I get a flat, I jump on the subway (this is very rare).

That said : I'm having trouble finding good t-shirts for this. I'd like to find something that is cool/wicks away sweat, has no logos/writing/designs whatsoever, is durable, well-made, fits snugly without being skin-tight, and is reasonably priced (so I can buy a bunch of 'em).

Any suggestions?
