Berghaus Volcanism Down Jacket - Green - L

It is water-resistant, meaning it provides protection against light rain and snow, but it is not a fully waterproof seam-sealed rain jacket.

Yes, it provides excellent warmth for skiing, though you may need a hard-shell outer layer if conditions are extremely wet or icy.

Store it in a cool, dry place in a hanging position or a large breathable mesh bag to prevent the down from becoming compressed.

The hood is generous but not specifically helmet-compatible, though it may fit over low-profile climbing helmets.

Hydrodown is treated to be water-repellent, meaning it dries faster and retains its loft (warmth) much better than standard untreated down if it gets damp.

This is normal for down products; gently pull the feather back into the jacket from the inside and rub the fabric to close the gap.

Tumble dry the jacket on low heat with dryer balls to fluff the down feathers, or give it a vigorous shake to redistribute the insulation.

Check for debris or fabric caught in the teeth and ensure the zipper is clean; a small amount of graphite can help lubricate stubborn sliders.
