Down Sleeping Bags Low Down
Lets get the low down on down. If you have ever spent a night outdoors, either camping or hiking and you spent the whole night shivering and desperately awaiting the sun rise, then you understand the need for a quality sleeping bag with the right temperature rating.
Down are the fine under-feathers that provide superior
insulation and warmth in waterfowl (ducks, geese). Down has long been used as
the epitome of warmth and luxury in beds, pillows, doonas, duvets, jackets
and…. You guessed it, sleeping bags.
Down as a filling is more expensive but has a better weight
to warmth ration and can be packed down smaller than synthetic fills. And when
cared for properly, a down sleeping bag can often last longer than synthetic
sleeping bag. And price will vary greatly over the range of sleeping bags
depending on the brand, quality, fill power and weight.
Why can a Down Sleeping Bag last longer than a Synthetic
Sleeping Bag?
Down as a natural fibre is surprisingly resilient, and can
withstand being stuffed (yes stuffed, and we’ll talk about that more later) and
restuffed time and time again. And a quality down sleeping bag can last for up
to 10 years, making the money you spend at the beginning well worth it in the
long run.
How small can a Down Sleeping Bag get?
Down is very compressible and its why a down sleeping bag is often the go-to for backpacking
and hiking. A quality down sleeping bag like the Nemo Sleeping Bag range can be compressed down into a parcel that is not much bigger than a water bottle!What is Down fill power?
Fill power determines the “fluffiness” of down feathers. And
if you have ever slept under a down filled doona, you know what we mean by
fluffy. You wake up in the morning and your bed resembles the Michelin man! Its
lofty and squishy like a giant marshmallow of warmth. And in terms of fill
power of a sleeping bag or even a down puffer
jacket it’s no different. Fill power reflects the ability fluff up trapping
more air (warm air) and provides a better warmth to weight ratio.
But there are some down sides to Down, all pun intended.
Water
Just like the Gremlins of the 1980’s movie or the Wicked Witch
of the West, Down does not like water! When Down gets wet it becomes a soggy mess,
and loses nearly all of it’s amazing insulating properties. This is where
synthetically filled sleeping bags come into their own, as they can retain
warmth even when wet. At Bundy Outdoors we would recommend investing in a light
weight waterproof
sack or dry bag to put your Down sleeping bag in, just to be on the safe
side.
Storing Down Sleeping Bags
Down sleeping bags do not get rolled, they get stuffed! That
is why you will see that most Down sleeping bags come with a “stuff sack” – the
Nemo Sleeping Bags come with both a stuff sack for use on the trail and a
storage stuff sack. By stuffing your Down sleeping bag, you can remove more air
from between the fibres allowing for a smaller pack size. Before you start
stuffing, flatten the sleeping bag out, then start at the foot end, this
usually traps the most air, and stack as you stuff. The foot box of the
sleeping bag goes into the stuff sack first, then progressively stuff and stack
the sleeping bag until you have the hood at the top. For added compression some
manufacturers stuff sacks will also have compression straps. When not on the
trail, a Down Sleeping Bag should be stored semi-lofted (loosely stuffed) into
a storage sack that has adequate ventilation. Don’t use a fully sealed plastic
bag.
Cleaning and Care for Down Sleeping Bags
You should always refer to the manufacturers cleaning and
care recommendations, as if you clean, and store a sleeping bag incorrectly you
could find you are not covered by warranty, and when a quality down sleeping
bag can cost any where from $250-$500, you want to make sure you get the most
out of it.

As with all sleeping bags regardless if it is a Down
sleeping bag or a synthetic one, hiking or camping, the best way to keep it
cleaner for longer, maintaining hygiene and lifespan, here at Bundy Outdoors we
always recommend using a sleeping
bag liner.
