This down coat is a winner. It’s incredibly warm—blocks cold winds easily—yet surprisingly light, no bulky feel. The sleek design pairs with jeans or dresses, and the pockets are handy for small items. Wears well for daily runs or casual outings. Minor note: sizing runs slightly snug, so size up if layering thick sweaters. Highly recommend for winter.
