What is the best down jacket for you? From lightweight mid-layers that sit beneath your waterproof shell, to toasty-warm belay jackets, here's our selection of the best on the market. 

Best down jackets

Down jackets have become a staple of winter wardrobes—they're not nearly as heavy as wool, but still keep you warm and toasty. You'll find that lightweight down jackets are great for all seasons too. They make for excellent mid-layers, or insulators: perfect for wearing beneath your waterproof jacket if you're venturing outdoors.

Down is not only warm, it's lightweight and packable, making it easy to stuff into your hiking backpack. If you're heading off on a camping holiday (to the Lake District, for example) or planning a long distance hike, saving weight becomes increasingly important, and you'll doubtless find down is your best option.  

Best Down Jackets: What to look for when buying

Down is usually sourced from geese and is rated on fill power—essentially how fluffy it is and therefore how much warmth it can trap. Anything from 500 - 800 is pretty normal for a down jacket, with higher fill power usually costing more. Despite most of the outdoor world using the metric system, fill power is still measured in cubic inches. The number comes from a standardised lab test, which measures how many cubic inches one ounce of down occupies with a standard weight resting upon it

Other things to look out for are the ratio of feathers to down. This will be listed as 90/10 where 90 would be the percentage of down and 10 is the percentage of feathers.

Another important thing to look out for when buying a down jacket is how the down was sourced. The Responsible Down Standard or RDS is the most recognised qualifier of a sustainable, humanely sourced raw material.

These days, many "down" jackets actually use artificial down: synthetic goose feather substitutes. This can have advantages. Real down tends to get clumpy and stops keeping you warm if it gets soaked through. Synthetic down substitutes usually dry quicker, and perform better (i.e. keep you warmer) when wet. But they're also normally heavier, and less warm than the real deal when dry.

To counteract the issue of real down's performance when wet, some companies now use "hydrophobic down". This means they use real feathers, coated in a waterproof substance. 

Best Down Jackets: TL/DR Summary

If you're looking for a lightweight down jacket that works as a mid-layer in cold conditions, or an outer layer in summer, then the Rab Microlight Alpine is hard to beat. Its combination of design, performance and price have earned it our "editor's choice" award. 

For those on a budget, you could do worse than Decathlon's Forclaz Mountain Trekking Hooded Jacket. It might not have quite the same warmth to weight ratio as more expensive models, and the build quality won't be as good, but you can't argue with that price.

Fill power: 700FP

The Rab Microlight Alpine Down jacket is widely recognised as one of Rab's most popular down jackets, and is often used as a benchmark for comparing other jackets in the same category. Despite having a fill power of 700, which is not the highest available, this jacket is still capable of providing ample warmth for chilly winter days. The jacket is made of 100% recycled Pertex Quantum outer material, which effectively blocks wind while remaining highly breathable.

The combination of the thin layer of down and Pertex Quantum material makes the Microlight Alpine a comfortable jacket to wear, especially when you're on the go. The jacket is equipped with two zipped hand pockets and an additional chest pocket for stashing more items. The excellent hood is filled with down, has a wired peak and adjusters, and fully protects your head. Further adjusters at the hem help to seal out any drafts, while the elasticated wrists provide a comfortable fit. The Microlight Alpine can be compressed easily, and fits into a small stuff sack.

The North Face Aconcagua Women’s Down Jacket - £200

The North Face Aconcugua

Fill power: 550FP

This windbreaker down jacket is intended for use while out hiking but looks good enough for everyday use, especially in the shady blue colourway. It mixes synthetic insulation in areas at the highest risk of getting wet, with 550-fill power RDS goose down in the body. The fill amount is trim enough for high-paced activities but still plentiful enough to keep you warm on cold winter days. The North Face’s proprietary Windwall outer fabric stops icy blasts in their tracks and the highly functional hood keeps your head warm throughout the day.

Mountain Equipment Lightline Down Jacket - £240

Mountain Equipment Lightline jacket

Fill power: 700FP

Mountain Equipment calls this a ‘technical duvet’, and we think that sums it up perfectly. Make no mistake, this is one warm down jacket. With 296g of 700 fill power 90/10 down you will be kept warm in the coldest conditions. Factor in an extended cut and you have a recipe for complete toastiness. The totally windproof 40D outer fabric is highly water resistant so will deal with light rain, and the adjustable cuffs and hem drawcord allow you to seal out draughts effectively.

Fjern Aktiv Down Jacket - £200

The jacket features a lofty 700 fill power down, which provides ample warmth in frigid conditions, making it a reliable standalone jacket. Its lightweight and packable design also makes it an excellent choice for layering during active alpine pursuits.

The jacket's Nylon ripstop outer and down-proof finish ensure durability and longevity, while the insulated and adjustable hood offers extra protection and warmth. The down-filled hood comes with a high collar for added face protection and comfort. The internal hood adjusters provide a streamlined finish and flexible fit, ensuring the jacket sits comfortably and securely on the head.

The Aktiv down jacket also features YKK zipped hand pockets, doubling up as a stuff sack. The stretch elastic cuffs and hem offer a flexible fit although we found the cuffs a bit tight.

Overall, the Fjern Aktiv down jacket is an excellent choice for those looking for a high-quality insulated layer that offers warmth, durability, and versatility. The only minor downside is the weight, with the Aktiv weighing in at 465g (size M).

Forclaz Mountain Trekking Hooded Down Jacket - £60

Fill power: 800

Let's get one thing out the way first: in terms of build quality a Decathlon-made jacket—even one that carries their slightly higher-end Forclaz label—is unlikely to be as durable, or last as long as the other jackets on these pages. If you're on a budget, however, it's impossible to argue with that price. Especially because from a technical point of view, this ticks a lot of boxes. 

Its filling has an 85/15 down-to-feather ratio, and is responsibly sourced, meeting the RDS standards. With 800 fill power, this is designed to keep you comfortable in temperatures as low as minus five when active, or plus five when not moving. Both figures have been certified using the standardised test in a thermal chamber. The Mountain Trekking Hooded Down Jacket has two zipped pockets, and can be folded into the left one for easy packing in your hiking rucksack. On top of that, it weighs just 290g. All that for £60? This really is a steal.
