Is the Therme Down Parka actually waterproof?

Yes. The shell is waterproof and windproof, so rain and wet snow bead off rather than soaking the down. Seams are sealed to keep water out.

How warm is it compared with a Canada Goose parka?

It is warm enough for typical city winters but less warm than heavy expedition-style parkas. In deep cold you will want a midlayer underneath.

The cut is trim. Most owners stay with their usual size for a close fit over a sweater; size up if you plan to layer heavily.

It uses 750-fill-power European grey goose down, which gives good warmth for its weight.

The clean, understated cut works over office clothes, but the trim fit can feel tight over a structured blazer. Try it over your usual layers.

The hood is adjustable and designed to stay on the jacket; it is not a removable hood.
