I like the stuff. I've a Micro Puff (coat and vest), DAS, a couple R4 and misc. long john top & bottoms.
Have almost all of that stuff too and agree.
If you're looking base layers, it's Patagonia Capilene over Under Armor any day of the week. I no longer own Under Armor anything. That said, the Capilene will still get stinky (problem with any synthetic) - just less so than UA.
