I bought three of the Sophie turtlenecks last year on a gold box deal... This year I treated myself again.  These sweaters are richly colored, well made and fully fashioned.  A great deal when on special.  I live in a climate where layers are key - most of the time, a tshirt & sweater are appropriate indoors, but it's abolutley necessary to wear a heavy jacket or parka when going out.  The lightweight comfort and warmth of cashmere is perfect.  These are definitely "2-ply" not the heavier, fluffier 4-ply.  Many reviewers seem to be expecting a heavier sweater - those sweaters are normally much more expensive, and in my opinion, are less versatile because they are so much warmer.  This sweater does run a bit small, so order the larger size if you're on the fence.
