I have a castelli mesh baselayer that I find much more comfortable and helpful than the UA in the heat. The UA was recommended in this thread and is half the price of the castelli baselayer though, so I thought I'd try it. Apparently, whoever recommended it doesn't live in a place where riding in 100+ degree temps is a norm.
