Is the Mackage Sullivan-Z warm enough for deep winter?

Yes. It is a down and feather filled coat with a windproof membrane, which suits freezing city winters. In milder weather, wear the shell or liner alone.

It is water repellent, not fully waterproof. The two-layer membrane sheds rain and snow, but a long downpour can still soak through seams over time.

What does 2-in-1 mean on this coat?

The down liner and outer shell can be worn together or separately. That gives you a lighter shell for fall and full insulation for winter.

Is the hood removable?

Yes. The hood detaches, so you can wear the coat with or without it depending on the weather and the look.

How should I clean a down coat like this?

Use a down-specific detergent and tumble dry low with dryer balls to restore loft. Avoid regular fabric softener, which can flatten the down.

When is the best time to buy it?

Down coats usually see the deepest discounts in late winter and early spring. At $1,490 at Mackage as of November 7, 2026, it is at full price with only one new listing.
