What really is UNDER ARMOUR? I see the advertisements and I've seen some folks here on the Eastern Shore of Maryland wearing it for cold weather waterfowl hunting?
As a very thin insulator, does it keep you warmer than the thicker wool or propylene underwear?
It's best described as performance gear. It wicks moisture away from your body, and is tight against your body giving some extra spring in your step. For example I wear the warm weather T-shirt when lifting weights, when I'm done the outside of the shirt is soaking wet, but when I take it off my skin is completely dry, I don't know how, it just is, this stuff is great.
