Best Down Sleeping Bag UK - Buyer's Guide


Finding the best budget down sleeping bag is not an easy task, because there are plenty of features that you need to look for before spending your money on a new piece of kit, for example, despite down being fantastic insulation, it does have its limitations versus synthetic sleeping bags.

Lets start with a basic definition of what is a down filled sleeping bag, followed by a host of relevant questions we've been asked on our Twitter recently.

What is a down filled sleeping bag?


A down filled sleeping bag is a sleeping bag filled with the plumage that is situated under the feathers of a goose or duck, close to their skin; and is one of nature's best insulating properties.

"Fill power" refers to the fluffiness of a down sleeping bag (and down products in general for example down jackets); basically the higher the fill power, the more air that is trapped between the down layers and the better it will be for insulation.

For example, a down sleeping bag rated at 600 Fill Power Down will generally be less insulating than a sleeping bag with 800 Fill Power Down. This is due to the quantity of the fill

Which is better down or synthetic sleeping bag?

Synthetic insulation is better than untreated down as it regulates insulation of heat even when wet. Down treated sleeping bags generally lose their insulation properties when wet. However, Hydrophobic Down treated Sleeping Bags have been shown to absorb less moisture overall and dry significantly faster.

What is a hydrophobic down sleeping bag?


Hydrophobic down is a water based PFC-Free waterproof coating that resists water and maintains effective heat insulation.

When regular untreated down gets wet, it is unable to trap air and provide heat insulation.

Hydrophobic down is a popular choice amongst those searching for the quality of a down sleeping bag combined with a waterproof coating.

However this article by mountain equipment provides a good counter-argument to not use Hydrophobic down. In essence they suggest that:

There's plenty of evidence that non-hydrophobic down sleeping bags perform just as well as hydrophobic bags, and many alternatives often have waterproof outer shells to compensate for the lack of hydrophobic down material.

How do you wash a down sleeping bag?

To wash a down sleeping bag you will need some down wash, a front-loading washing machine, some tennis balls to break apart the clumps and ideally a front loading dryer. Always read the washing instructions on the label on your down sleeping bag, as some may have different requirements.

Below are some of the down sleeping bags that the team here at ArcticDry have used in the past, and can recommend if you're thinking about getting a down filled sleeping bag for your next adventure!

AEGISMAX Ultra-Light Goose Down Sleeping Bag

The AEGISMAX Ultra-Light Goose Down Sleeping Bag is a fine example of a quality piece of kit that you can pick up for less than £100.

It is made from duck down and has a lofting power of 600, as well as being made with waterproof nylon fabric.

If you're thinking to purchase a sleeping bag that is small when packed then this is a perfect choice for you, coming in at only 30 x 18 cm, it comes with a drawstring design allowing you to neatly back everything away at the end of your hike.

Naturehike Ultralight Goose Down Rectangular Sleeping Bag


The Naturehike Ultralight Goose Down Sleeping bag is a high quality rectangular sleeping bad with 800 Fill Power Goose Down, one of the highest numbers on this list in terms of down fill power.

It's rectangular design will suit those who want a bit more space in a sleeping bag as opposed to something that is tighter and potentially more restricting.

It has a recommended limit of 2 degrees celsius, which should be more than fine for most outings in the UK, apart from when it gets really cold. However, with a fill power of 800, this is a seriously warm sleeping bag from Naturehike.

Hyke & Byke Down Shavano Sleeping Bag


The Hyke and Byke Goose Down Sleeping bag comes with a 370-410 Fill Power Down Filling, and is generally recommended as a 3 season sleeping bag, Spring, Summer and Autumn.

The total pack weight is 2.02 / 2.13 / 2.24 lbs (2.2lbs in 1kg remember..), which isn't too shabby, but isn't super lightweight at the same time.

The biggest advantage of this sleeping bag is that it's made from Hydrophobic Duck Down, which as mentioned previously in this article, is a big bonus over regular down due to the fact its waterproofed and protected from getting soggy and losing its heat insulation.

LMR Outdoors Ultralight Mummy Down Sleeping Bag


The LMR Outdoors Down Sleeping Bag is a fine example of a cheap, yet well performing sleeping bag. Coming with a 700 Fill Power and 1000g Duck Down, it's a great performer and can be used as a 4 season sleeping bag.

The Outer Shell comes with a 400T waterproof nylon fabric, which is super handy to have in this UK weather.

Its overall weight is 1.6kg, which certainly isn't the lightest on this list, but for a sleeping bag that has 700 fill power and a waterproof outer shell, it's a fair weight.

700 Fill Power Waterproof Outer Shell Not the lightest bag


There we have it, our list of the very best down sleeping bags under £100. There actually aren't many, or rather many that we'd like to feature and that aren't too cheap to be worth using.

Many of these brands also offer down filled sleeping bags between £100 and £200, and these are often better quality, so please also check out other products by the manufacturers we've featured today.


What the best down sleeping bag under £200?

This definitely requires another article to cover, but in general, from the brands we've seen in the past, there are a few we would recommend, such as the Marmot Unisex Ironwood 20 Down Mummy Sleeping Bag, which is a very high quality 650 Fill Power Bag with a whole host of good features.

Duck Down v Goose Down, Which is Better?

Goose down is generally considered better than duck down as geese are larger birds and their down clusters are larger and have a higher lift and yield a much higher fill power.

However, when thinking about purchasing a down sleeping bag, you will be perfectly fine with both, especially for beginners starting out, you probably won't notice the difference between the two.
