I like the jacket because it’s not as heavy as the authentic military version. But I’m not a size ‘Olive’ and my preferred color is not ‘Large’. Attention to detail!
It’s obvious - the choices for “color” refer to the relative wavelength of reflected light, and the choices for “size” refer to the shade your face will turn if you buy that size and try to zip it up all the way.
See, you get it. Good job!
