The 6 Best Down Jackets of 2026: Ultralight to Expedition-Warm

A down jacket is the highest warmth-per-ounce purchase in outdoor gear. We wore six of the best through a season of frosty belays, cold-soaked camps, and single-digit mornings to find which ones deliver.

Arc'teryx Cerium — Best Overall

The Cerium pairs 850-fill down with synthetic insulation mapped into the collar, cuffs and underarms — exactly where moisture collects. The result is a jacket that stays lofty through sweaty approaches and drizzly camps where pure down wilts. The trim fit layers perfectly under a shell.

Pros: brilliant hybrid insulation mapping, superb fit, packs to grapefruit size. Cons: premium price, 10D face fabric demands respect around brush.

Patagonia Down Sweater — Best Everyday Value

The jacket that defined the category still nails it: honest warmth, a fit that works over a fleece or a t-shirt, and NetPlus recycled nylon. It's a few ounces heavier than ultralight rivals — and a hundred dollars cheaper than most.

Down vs. synthetic — the 60-second version

Down wins on warmth-to-weight, packability, and longevity (10+ years). Synthetic wins when soaked and costs less. In dry cold, buy down; in sustained wet, carry synthetic. Our full down vs. synthetic guide has the details.

How we tested

Each jacket was worn for a minimum of 20 days across a cold season: stationary warmth tests at 25°F (how long until we reached for another layer), packability against a 1L bottle, and loft retention after 10 compression cycles. We also tracked snag and abrasion damage from normal use.

Frequently asked questions

What fill power should I buy?

650–700 fill is the value sweet spot; 800+ saves weight for the same warmth. Fill weight matters as much as fill power — a thin 900-fill jacket is still a thin jacket.

Can you wear a down jacket in the rain?

Briefly, or under a shell. Sustained rain collapses down's loft and its warmth with it. In wet climates always pair down with a real rain shell.

How do I wash a down jacket?

Front-loader, down-specific soap, gentle cycle, then tumble dry low with dryer balls for 2+ hours until fully lofted. Never dry clean, never store compressed.
