Putting this shirt on the
Putting this shirt on the first time, I was sure I would be uncomfortable very fast since wearing a long sleeve shirt during the heat of Summer to stay cool was totally not in my mindset. However, after riding my bike on a very hot and humid day for over an hour; I still felt comfortable. I won't say cool but I believe I was more comfortable than if I wore a short sleeve t-shirt. I do know I could feel the air move under the shirt through the side vents which was a good thing.
No issues with the purchase process. The purchase and shipping were as I would expect.
