Don't know how I ever managed without this! Perfect base on it's own when temps are mild, and excellent with heavier long sleeve base-layers when the mercury plunges. The only thing I would change: crew-neck instead of V-neck, and more coverage for the kidneys and lower back. Other than that, I love it! White is a welcome change from all the dark layers and the Wind Stopper fabric is very supportive (controls those love handles so you look slimmer) and flattering.
