How warm is the Payton Pass II?

It is built for cold winter days, combining synthetic insulation with the Omni-Heat Infinity reflective lining. It handles snow and wind chill well for everyday use, but it is not rated for extreme expedition cold.

Is it actually waterproof?

Columbia describes the shell as waterproof-breathable, so it sheds snow and rain while letting vapor escape. Seams and zippers are the usual weak points in any jacket, so treat it as a winter parka, not a rain shell for long downpours.

How does it compare with a down parka?

Down gives more warmth per ounce and packs smaller. This jacket's synthetic fill keeps insulating when wet and the reflective lining boosts warmth, so it suits wet, slushy winters better than down.

Does the hood come off?

The hood is sherpa-lined and adjustable. Columbia lists adjustability rather than a removable hood, so plan on it staying attached.

What should I wear under it?

A base layer and a midweight sweater are enough for most winter days, since the reflective lining traps heat. Size it to leave room for a sweater without compressing the insulation.
