From a 7-oz ultralight layer to a parka that laughs at single digits — six down jackets our testers trusted through a full cold season.

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.

## Quick picks

| Jacket | Fill | Weight | Price | Best for |
|---|---|---|---|---|
| Arc'teryx Cerium | 850 goose | 9.5 oz | $400 | Best overall |
| Patagonia Down Sweater | 800 goose | 13.1 oz | $279 | Everyday value |
| REI Co-op 650 Down 2.0 | 650 duck | 11.6 oz | $129 | Budget |
| Mountain Hardwear Ghost Whisperer/2 | 800 goose | 8.8 oz | $360 | Ultralight |
| Rab Microlight Alpine | 700 recycled | 16.6 oz | $290 | Damp climates |
| Feathered Friends Eos | 900+ goose | 10.6 oz | $349 | Warmth per dollar |

## 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](https://peakpinegear.com/guides/down-vs-synthetic-insulation) 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](https://peakpinegear.com/guides/best-rain-jackets-2026).

### 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.
