Cold-Weather Fabrics Explained: Wool, Cashmere, Fleece & Down
Walk into any store this month and the sweaters all look similar — until you read the labels. One sweater is 100% lambswool for forty dollars; the one next to it is a wool-blend for twice that. A puffer claims 800 fill power while its competitor doesn't mention fill power at all. The price tags don't tell the real story. The fabric content does.
We spend our days deep in fabric references and textile guides, so here's the plain-English version of what actually keeps you warm — and how to buy pieces that earn their keep for years.
