I was first attracted to this vest for its homespun look¿a change of pace from synthetic fleece tops. "Great for around town," I thought. I didn't expect this sweater's performance attributes. Made from a 100 percent Icelandic wool and mohair blend that's brushed into a lofty fleece, the vest is lightweight, breathable, and comfortable over a wide temperature range. Also, the wool fibers do not absorb moisture, so the vest kept me warm even when it got wet. Wool-sensitive types might find it a bit itchy.
