This is a Columbia Omni Heat Thermal Reflective Winter Jacket. Size is Mens Small. There is a little bit of discoloring under the left arm of the jacket. It isn't as bad as the picture makes it look. Other than that slight discoloration, the jacket is in excellent condition. I would say that the color of the jacket is slate gray, which can appear to have a little bit of navy tones to it when looking at it in certain light.
