I've never worn the thing.  I can't personally speak to the warmth or comfort or anything like that.  It seems of decent quality, though.  My girlfriend has literally 25+ scarves and she wears it a lot... probably like 15%-20% of the time, which is pretty good odds considering all the other ones she has.  She says it's one of her warmest, plus it's also a neutral color so she can wear it with a lot of different things.

If you're a guy looking for a cheap present for a girl, you can't go wrong.

Also get her a black and white keffiyeh while you're at it.  One of the ones with the tassels.  My gf wears that a lot too.  They look pretty cool and are also sorta neutral in color.
