How warm is the Aconcagua compared with a down parka?

It is a solid cold-weather coat for typical winter temperatures, but a fill-power down parka gives more warmth for the same weight in deep cold. The synthetic insulation holds up better if the shell gets damp.

The shell is weather-resistant, not fully waterproof. It handles light rain, snow and wind, but sustained heavy rain will eventually soak through.

How does it fit for layering?

The cut is streamlined rather than boxy, so it layers over a sweater or light fleece but can feel snug over heavy knits. Consider sizing up if you plan to wear bulky midlayers.

Can I wear it for hiking or skiing?

It works for casual winter walks and travel, but it is designed for urban use. For skiing or serious alpine activity, a technical shell with a helmet-compatible hood and taped seams is the better choice.

How should I care for the insulation?

Wash it on a gentle cycle with a mild detergent and tumble dry low with dryer balls to restore loft. Avoid fabric softener, which coats the synthetic fibers.
