Well I haven't worn UA, but I have various different makes (Terramar, Wickers, Montana Mountaineering, & White Alpine) of base layers which work very well and are made primarily of polyester (including what's called Polartec Powerdry), so I find the suggestion that polyester is "god awful" to be an unhelpful exaggeration of whatever shortcomings it has compared to the UA products. I expect that the weave and various ways the fabric is treated make a big difference in the end result (I majored in fiber arts in college), but the fact is that polyester does not hold onto moisture like cotton does, it allows it to evaporate readily. If this were not so, then there wouldn't be so many companies (including Hot Chillys, Mountain Hardware, Lowe Alpine, Terramar etc.) using it. I'm not saying it is the best, but that it is quite functional in allowing evaporation of moisture.
