as said above.... go to wally world and get it. Its the same stuff, just 9 bucks instead of 30! I always get 2 sizes up so its not so tight. As you said, I dont like tight stuff. I still wear thermos though when its very cold out though. I only use the underarmor type stuff when its early season and hot out. They also make loose gear now which fits very well
But still, its pricey
