People here dislike synthetics for daily wear, not necessarily for sports use: I think most people who actually sweat (sports, HIIT, strength training, etc) will concede that cotton is just about the worst thing to wear. Synthetics definitely win the day in the gym.
One exception I would say, for some applications, is merino wool baselayers, which I definitely prefer over synthetics for hiking, mountaineering, etc. I wouldn't wear it in the gym, though, since even merino (miracle wool that it is) doesn't have the evaporative (ie. cooling) qualities that synthetics have.
As for $90, technical and fitness clothing can certainly get on up there (my wife is a devotee of Lululemon or how ever you spell it), but honestly I just grab the stuff deep-discount at Ross; the clothes I wreck with CrossFit, 5Ks, and Spartan races is $5 shirts and the like (though they might be $50 suggested retail, who knows?)
