Patagonia Tres 3-in-1 Parka vs Rab Women's Deep Cover Down Parka

Buy the Patagonia Tres 3-in-1 if you face wet, windy winters and want one jacket that covers three temperature ranges. Its H2No shell is genuinely waterproof and the zip-out 700-fill down liner works alone or under the shell. The Rab Deep Cover is the warmer, simpler pick: a longer thigh-to-knee parka with more down coverage and a two-way zipper, but its recycled fabric handles only dry to mildly wet cold. Reviewers consistently praise the Patagonia's versatility; the Rab wins on length and warmth per layer.

• Choose the Patagonia Tres 3-in-1 if you want a waterproof shell plus a removable down liner that covers fall through deep winter and wet coastal weather.
• Choose the Rab Deep Cover if you want a long, warm down parka for dry cold and everyday winter wear, and you don't need a waterproof shell.
