This is a catch and release and the color is hard to capture. It’s more of a dark warm plum than a cool toned purple. Previous owner removed the tag, so I don’t know exact fabric content. I think it’s the same shirt I found online as that looks like the correct color , but not sure. It’s lightweight, so compared to other smartwool I have it would make sense it’s the 150. I just can’t guarantee it’s not a blend
