Is the Mackage Bergen warm enough for below-freezing weather?

With 90% down fill and a hood, it handles typical winter cold well, especially over a midlayer. For extreme cold or long exposure, a heavier parka is the safer choice.

How does it fit compared with other down jackets?

It has a straight cut that runs trim through the chest and shoulders. If you plan to wear thick sweaters underneath, consider sizing up.

No. The nylon shell resists light moisture and wind but is not a waterproof membrane. It is not the jacket for heavy rain.

Can the hood be removed?

No, the hood is fixed. That keeps it simple and warm but means you cannot strip it off on milder days.

How should I wash a down jacket like this?

Use a down-specific detergent, wash on a gentle cycle, and tumble dry low with dryer balls until the fill is fully lofted. Avoid regular detergent and high heat.
