Introduction
This article features lightweight down parkas (usually, full-zip jackets with hoods, a longer hem, and box-baffled construction) appropriate for winter backpacking, snowshoeing, backcountry skiing, mountaineering, and other cold-temperature activities.
What is the best down parka? The answer: it depends, of course.
I researched over 50 models and selected 12 to use over two years of outdoor activities that including lightweight backpacking, alpine climbing, mountaineering, backcountry skiing, and multi-sport expeditions.
The objective of this article is to give you some education about down parka design and performance that will help guide your decision-making process when selecting a winter-worthy parka.

The Montbell Frost Line is my recommendation if you're on a budget. It's not the warmest parka at this weight, but it's by far the best value here. This parka earns our Recommended rating for its value.

Feathered Friends Hooded Helios Jacket - $359/17.1 oz

The Feathered Friends Hooded Helios Jacket is probably the warmest down parka on the market that uses sewn-through baffles. Warmth is going to be very difficult to beat at this weight, but the parka has a short length, so it's best for users with shorter torsos. This parka earns our Recommended rating for winter backpackers with shorter torso lengths.
Feathered Friends Khumbu Down Parka - $599/34.6 oz

If absolute warmth, a voluminous expedition cut, and durable waterproof fabrics are required for you to stay comfortable while stationary for long periods of time in frigid conditions (mountain guides and people who work outside come to mind), then the Feathered Friends Khumbu may be for you. This parka earns our Recommended rating for professionals who work outside in extremely cold conditions.
