-I wear UA underwear. They cost more than other underwear. (Approximately $20/pair at outlet in states) I find them to be well worth the money and they do keep me dry.
Shirts/shorts are pretty good too I wear them when I work out. Softer than Nike.

-I find Nike dri fit to be not as good for wicking away moisture. They feel like just any ordinary polyester to me. I read somewhere that Nike dri fit quality went downhill once started using recycled stuff.

-Costco's Paradox base layers are OK. I wear them under my Carhartts when I work outside in the cold all day. I suppose they are OK for wicking away sweat since I stay relatively dry.

I've always washed all of the previous items after one use. I sweat quite a lot.

Off topic... but when you sweat you release all these fats/oils the bacteria come have a partying/orgy and multiply like crazy. Then they make poo poo all over and that's why it starts to stink. This is why I wash my sweaty clothes after one use.
