Why did you reply "none" ?
The blue one is OK I guess, I just don't really think it's that versatile. I disagree with the other poster in that I think gray is more versatile since you can wear it with any color coat - black, charcoal, brown, etc. I couldn't see wearing the blue scarf with a black overcoat. I like the color of the gray one, but I really don't like the ribbed texture at all. I'm sure I would probably like the woven gray H&K one you mentioned.
