Is this coat warm enough for freezing weather?

It is a puffer, so the quilted insulation traps body heat well for cold winter days. It is not a down expedition parka, so pair it with layers in deep cold.

Does the longline length get in the way when walking?

A longline puffer reaches past the hips toward the thigh, which adds warmth but can restrict stride. It suits standing and walking commutes more than hiking.

Nothing states a waterproof membrane or sealed seams. Treat it as water-resistant at best and use a shell in steady rain.

Can the hood be removed?

The hood is part of the coat, so it stays attached. That helps in wind and snow but adds bulk when you don't need it.

How should I style it?

It is a casual piece, so wear it over a tracksuit, hoodie and jeans or joggers. It is not cut for tailoring or formal outfits.

What do I wear under a puffer this long?

A mid-layer such as a hoodie or fleece works well, since the coat already handles wind and insulation. Keep the base layer thin to avoid overheating indoors.
