As the title says I'm looking winterish long-sleeved undershirts. I've never had Under Armour Coldgear stuff, but I'd imagine that's what I'm looking for. Currently I have some cheap UA knock-off from target which I really like. The problem is that the bottom (waist) part is not long enough. They won't stay tucked in and it really frustrates me. The other part is I am an avid cyclist and I've been recently running more. I would also like to use these products as a base layer for these activities. Again these shirts would work, but they're much too short and won't stay down. What say you CT? I like the specs of UA on paper, but they seem rather expensive at ~$50 apiece. Thanks!
