Lives in my rotation

The fir green is even prettier in daylight. Fits close without clinging, and it came out of a cold, gentle wash looking new.

The coat I was looking for

Warm enough for a wet Portland morning without feeling heavy. The wool is soft and dense and the shoulders sit right. The size finder said S and it was spot on.

Sharp and actually warm

Wore it all week in the rain over a sweater. The collar stands up properly and the buttons feel solid. Sleeves were a touch long for me, an easy fix at my tailor.

Softer than I expected

No itch at all, and no pilling after a month of weekend wear. The cream is warm, not stark white.

Broke in fast

Two days of walking and they were comfortable. I went half a size up for thick socks like the size finder suggested. Perfect.

Great on the trail and in town

Shed a full afternoon of drizzle in the Gorge. Pockets are deep enough for a phone and gloves.

My favorite coat this fall

Cozy enough for early dog walks and still polished for coffee after. I'm 5 ft 4 and the XS was right.

Elegant and easy

Wore it to a wedding with boots and a blazer. The knit drapes nicely and doesn't cling at the hips.

Lovely packaging, fast delivery

Ordered on Monday, arrived Thursday. Everything wrapped in tissue, no plastic mess. The scarf is generous and very soft.

Classic and well made

The navy is rich and the lining is smooth. I exchanged for a size up and the team answered my email the same morning.

Exactly as pictured

The oat color is soft and warm, just like the photos. Real horn buttons and a cable that keeps its shape. Shipped the next day.

Warm without the bulk

Light enough to wear all day, warm enough for frosty mornings on the lake. Got compliments twice on the first trip.
