I have an Ibex that's about three years old. Short sleeve in blck and grey (the grey is under the arms and kind of down the sides) am looking to replace or add to.
The Woolies is a good option. Also check out the Icebreaker Tech T. It's a very nice piece.
This one is definitely a great option, or check out the U-Sixty T, which is a little bit more of a relaxed fit, but same fabric weight.
