FYI for anyone considering trying them, there's currently a 30% off sale at Icebreaker.
Those prices are being matched at Amazon and other vendors, so you can find the Tech T in just about any color for $50 (vs the usual $70). Still not cheap, of course, but a little less painful.
I found the Tech Polo on sale at Campsaver for $39 -- a significant discount off the usual $105 price.
While I don't usually wear short-sleeved pullovers, I will make an exception for this one -- it is easily the best polo I've ever owned.
Even in the super-humid 95F temps here, it breathes, remains comfortable, and doesn't hold onto odors like cotton does. (The black Merino does hold onto pet fur like a magnet, though!)
Both are so lightweight that I'm still being a little cautious to avoid snagging them on anything. Hoping they will prove durable, because they are going to make it very hard to go back to cotton.
