What is down insulation? Are down insulated jackets cruel?

Despite being used in many household and clothing items, often people are not aware of down and how it is obtained.

Whether it’s the lining of pillows, duvets, cushions, sleeping bags, coats or even gloves, there’s a whole host of products that use down feathers for insulation. Down is generally the underlayer insulation birds use to keep warm, which is ripped from them. To be most cost-effective, the birds are sometimes kept alive (unless they die from shock) to be plucked as soon as new feathers have regrown.

So yes, down insulted jackets are very cruel. That’s why we wholeheartedly recommend switching from down to synthetic products. If you want to find out a bit more then check out this post on down feather from Your Daily Vegan. 


Introducing… synthetic insulation!

With the huge rise in veganism and demand for sustainable outdoors gears, plenty of research and resources have gone into synthetic insulation. This has meant that high-performing insulated jackets are both vegan-friendly and easy to find.

Brands that are really pioneering is are Patagonia, Colombia, North Face and Marmot each with their own line of insulation technology (more info below!).

The high-tech vegan materials now available that completely rival down filling, often providing jackets which are:

  • Better in wet conditions
  • Faster drying
  • Often much cheaper (yes!)

With insulated jackets being such an essential part of your outdoors trip it’s awesome that you now have a huge vegan selection available.

Note. these awesome items of outdoor clothing may be labelled as vegan insulated jackets, synthetic insulated jackets, vegan down coats or maybe just insulated jackets. Don’t be thrown off by the different names!

1 . PrimaLoft

Originally developed for the US army, PrimaLoft is a high-performance synthetic technology, with great warmth to weight ration. They also make a conscious effort to use environmentally friendly materials which are all 100% vegan – awesome. This is in the jacket I use and I love it.

Looking at an insulated jacket which doesn’t use these types of insulation? Don’t worry!

Using the big names in insulation comes at a high cost so many budget brands won’t use them. To make sure your insulated jacket is vegan-friendly check the label for:

Vegan insulated jacket buyer’s guide

Are you wanting a lightweight layer to keep with you at all time? Looking for extreme warmth in harsh conditions? Maybe you just want a warm vegan winter coat to keep you cosy around the house? With so many options now available to you happy herbivores it can make picking the right vegan coat quite time-consuming. This buyer’s guide below to help you find the right thing. 



In honesty, an insulated jacket isn’t going to be the cheapest item on your kit list but it’s worth buying the best product within your price range. It’s not actually the vegan aspect that makes it more expensive, they’re generally cheaper than down equivalents. 

When warmth and safety are involved it’s crucial to get something which suits your environment and use. Picking the right coat for your conditions will not only make your time in the outdoors more enjoyable but will last for years and save you money in the long run. 

This doesn’t mean you have to spend lots of money but if you are going to spend more on outdoor gear, it’s worth spending it on a good coat and saving on less important items. 

Generally, these are the kinds of prices you can expect to pay for reliable insulated coats

  • Budget – £60 or less
  • Midrange – £110 or less
  • Top range – £160 or less
  • Arctic expedition – £200+

Size and weight

Most synthetic insulated jackets are designed to provide the most warmth with the smallest size and weight. The more money you pay the better warmth to weight ratio you’ll find, generally.

With that said, most of the jackets on this list weigh less than 500g and are designed to be easily compressed and stowed away when not being used. 

Think about the conditions you’re likely to be in. If you’re heading into the extremes it’s seriously important to pick a jacket with the right level of insulation. On the other side, is it worth paying more money and carrying more weight if you’ll only be experiencing mild conditions? 


Waterproof? Windproof?

Almost all of the insulated coats on this list are windproof and water-resistant but it’s also possible to get waterproof ones. This normally comes at a high price and you might be better off wearing an insulated jacket and a waterproof layer over the top. 


Hoods and Pockets?

If you want to keep as warm as possible then a hood is a must. Activities may need a helmet (climbing, mountaineering etc) so make sure the hood is large enough to go over a helmet or is designed to go underneath. If your activity requires lots of gear then maybe it would be useful to have multiple pockets to keep things in?


What’s your colour?

Do you want to be seen? Do you want to be hidden? Are you going to be in green woodland areas or white snowy areas?

Sarah currently wears: Columbia Powder Pillow Hybrid Synthetic Jacket

Weight – 500g

Insulation – Omni-Heat™ synthetic insulation

Best for – Overall outdoor adventures in mild to cold weather

Cost – £60

Sarah has been rocking this for the last 6 months and is a big fan. It’s been used cycle touring, hiking, camping and climbing and has been pretty damn perfect. The water-resistant outer shell is very useful and deals with even heavier rain easily, all whilst keeping you warm and dry. It’s very comfortable and hard-wearing; after tearing through bushes and scraping along rocks, there are no tears or snags. 

“It’s not designed for extreme cold but it’s perfect up to -5°C and as soon as you’re moving it retains all the heat – ideal for adventuring. Overall I’d say it’s a perfect budget option for a round-the-year active insulated jacket, you’ll struggle to find better value for the price”, Sarah.

Josh currently wears: The North Face Thermoball Insulated Jacket

Weight – 450g 

Insulation – PrimaLoft™ Thermoball™ synthetic fibres

Best for – Lightweight warmth for every everyday action – perfect under a waterproof!

Cost – £90

For me, this is another awesome option for an active insulated jacket. Before we left on our RTW cycle tour I wanted something lightweight to use as a thermal mid-layer with a waterproof on top.

The Thermoball has been great because it’s incredibly practical. The jacket is very small and lightweight, with good ventilation and compresses down to a tiny size, so when you’re not overly active it can be worn in warmer climates too. As soon as you start moving the jacket really insulates well and keeps you warm even through harsh conditions. 

I love it, have barely taken it off, and highly recommend it to anyone looking for 3-season warmth or the ultimate mid-layer.

  • I would say that not all down is live plucked. Most major outdoor companies now follow RDS rules regarding down, the first of which is that live plucking is prohibited. RAB have a section on their site which gives the details.

    That being said, the Atom LT and Patagonia Nano Puff are two of my favourite jackets and great suggestions. Atom also comes in SL and AR versions depending on whether you run warm or cold. I opt for synthetic jackets 90% of the time as they retain warmth when wet.

    • Hey, yes I’ve rephrased that sentence as we weren’t trying to give that impression. It’s great that brands are moving away from such a horrible practice and also choosing to bring awareness to down online which is a good step.

      The Atom LT is a very nice jacket indeed, they have a new one coming out in the new year which will be exciting to see! As a brand I think Patagonia do a great job and it’s very cool to see them using more and more recycled materials – hoping more follow suit too. What do you tend to use your jackets for? Do you have a particular outdoors activity you use them with?
