Adidas Climachill

When I saw Sam Winebaum of RoadTrailRun reviewed and loved the Adidas Climachill 2nd generation running shirts, I ran out and got one (figuratively over the 'net).  I'm pleased to say it doesn't seem like a case of overhype (not that Sam falls for that kind of stuff anyway).

I wore the shirt for the first time on a 16M run/50 min walk/1M run.  I felt like I'd have an opportunity to see how it worked under a variety of conditions -- hot and humid outdoors, both under overcast and sunny skies, and inside on the treadmill.

From a very subjective viewpoint, the shirt seemed to do really well when there was a slight breeze (I assume this puts its enhanced evaporative qualities into overdrive) and indoors when sopping wet with sweat.  When I was running in still air, particularly in overcast conditions, it didn't feel much different from a Dryfit shirt.  But even when I didn't feel cooler, I liked the general cut and comfort of the shirt.

Given its fairly respectable $30 pricing on Running Warehouse, I'd say it was a worthwhile purchase.  Use the link in Sam's review so he'll have more money to do his super write-ups.

Edit 7/28/15: I wore for an entire 6 hour run in dew points over 60, temps in the 80s - and didn't change it once.  Several times I felt cool with a slight breeze!  It didn't help my calf cramps, but that's not on the label.
