Really so you have worn UA? Since you know how pantyhose work; I guess you have worn those also
BTW I have not worn UA so I do not know how it works, but I have used PolarTec products and they work great. I am about 40% less bulky with polartec in cold weather.
That's why I like the UA. So much less bulkiness than other long underwear. In the past I have used long underwear that was so bulky it was hard to pull my bow back. For bowhunting I like to dress as warm and bulk free as possible. UA makes this possible.
