Ajay Bhat wrote a review of Under Armour Base 2.0 Crew Top - Men's on February 11, 2012
I live in upstate NY and have taken to running recently. I love running outdoors and not on a treadmill. As the weather isn't particularly warm here I needed a layer to keep me warm during those cold days (of which there are many).
I found the Base 2.0 and have been using it for some time now. I am comfortable wearing just that down to ~25 degrees. When its snowing I just add a rain jacket on top of this and I am all set.
It breathes well and I don't feel suffocated wearing this.
Initially I wasn't too sure about paying so much for this but now that I am using it I know it was worth it.
All in all, I am a happy runner now.
I am 5'11'', ~170 pounds, got a size LG. Fits me comfortably.
