How is the quality of the J. Crew merino wool sweaters. I've bought BR ones over the last couple of years, and I need to mention, I no longer own them, which speaks to the quality of their sweaters (why they blend materials is beyond me). Anyways, I want to pick up some v-necks from J Crew in black, navy and dark grey. How is the quality on these bad boys? edit: Also, how is their version in lambswool?
