Is the Herno Windstopper coat actually waterproof?

The shell is waterproof and water-repellent, so it sheds rain and snow. Seams and the down fill still need care in sustained heavy rain, so it is best for city weather rather than storms.

How warm is it compared with a down parka?

It is a quilted down jacket, not a long parka. It handles cold, windy days well over a sweater, but a longer, heavier parka will be warmer in deep winter.

Does it fit true to size?

Herno cuts close to the body. Most buyers stay with their usual size for a trim look and size up if they plan to wear it over a suit jacket or thick knit.

Can I machine wash it?

No. The down filling and two-layer membrane call for specialist cleaning, and machine washing risks clumping the fill and damaging the shell.

What is the difference between the 2 Layer and 3 Layer Windstopper versions?

The 2 Layer version bonds the membrane to the outer fabric for a softer, lighter feel. The 3 Layer adds a separate lining for more structure and durability, at the cost of some weight and softness.
