I have owned this top for running for 7 years and it is still going strong. Washes up good, fits great (although it don't appreciate a lot of compression, size up) and keeps you warm. I hike, run and ski in this guy. Minus the color now being grey from some rough activities you would never know how old it is.
Got this for Christmas and have already worn it a few times for running in the cold here in New England. Great to throw on under a t shirt or wear as-is, UnderArmour continues to make a good product that will keep you warm without being too hot. Wish I could get this in more colors.
