Icebreaker Superfine Tech T
I have one of these Icebreaker shirts and I've bought one for each of my brothers. We all agree: these are kickass shirts. After 3 days of intense backpacking in 90-degree heat, I could still wear this performance tee to the bar without making the barmaid turn green. They have a nice slimmish fit - not tight by any means, just a contoured shape. Another bonus: they insulated like no other. I was caught in a cold hailstorm without a rain coat (real smart). I was chilly, but not nearly as cold as I would have been in a synthetic or cotton shirt. HIGHLY recommend any Icebreaker product. This is a good, simple performance tee good for everyday stuff and backpacking.
