The Marmot Montreaux is a women's knee-length puffer coat filled with 700-fill-power down and rated for cold winter wear. It stands out for its long coverage, attached hood and water-resistant shell, which make it a practical city and commute coat. At $100 at Poshmark as of November 5, 2026, it sits well below what a 700-fill down coat of this length usually costs, though that is a resale listing and new-stock prices at the other stores run higher.
