I am trying to track down a source for this shirt and I'm not having much luck. I got it from a race recently and I've found it to be one of the better wicking shirts I've worn. Does anybody have a clue what model this is and where I can buy some samples? Google turned up nothing and the Zorrel web site is less than helpful. It does not look like it's a cotton/poly blend. No other info on the tag except that it's made in Thailand.
