This tank is great for layering or to wear alone, although beware - it fits snug. I normally wear a small so I bought a small and it is great under things, but I just ordered a medium so I can wear it alone too. The fabric is really soft and feels great against the skin, but also moisture wicking,s o you can run in it. Pretty colors too!
Tried the Orange burst for the first time on a 1/2 Marathon. I was truely amazed. I never lost my edge. I took it at the begining and at mile 8. Just was impressed with it for the little investment, how big of a difference it made for me. I will be using it more often for my longer races.
