Which
sleeping bag fill is the best for you? It depends on how, when,
and where you will be use your sleeping bag. For example, if you
are camping out with the family and not moving around. A family
sleeping bag that is medium weight and less expensive is right for
you. However, if you are backpacking and you are going to be
carrying your bag to a new location every day. You will want to
look at the lighter
bags. Finally, if you are going on a mountain climbing
expedition where it will be very cold, you will want to choose a warmer
bag perhaps a down bag. Things to consider and general tips are
presented below. The table below show a comparison of bags by the
fill material.

Note about temperature ratings: Ratings are only a guide in helping you
decide on a bag that best suites you needs. There are many
uncontrollable elements that cannot be accounted for in determining
temperature ratings. If you are not sure that a bag is warm enough for
your intended use we recommend purchasing a higher rated bag to make
sure that you have years of satisfaction and are not stuck with a bag of
limited use.
Things
to consider
What
will this sleeping bag be used for?
What
temperature range and seasons will it be used in?
Do you
sleep cold or warm?
The majority of sleeping bag users are fair-weather campers,
and a general temperature range for summer or cottage users
in North America is -5°C to 10°C. If you tend to get cold
when you sleep, we suggest purchasing a bag with a rating 5°
to 10° warmer than what you think you will need.
Is it
likely to get wet?
No one expects to end up with a wet sleeping bag, but if it
is going to be used for water activities or open air
sleeping, attention should be paid to how the insulation
behaves when wet. Down loses its insulating capacity when
wet, though it dries quickly hung up in the wind and sun.
Synthetic fills retain their insulating capacities better
than down.
Will it
be carried a lot, and therefore must it be light and
compact?
The ideal insulation would be extremely warm, compact,
light, stay dry, and be inexpensive. Unfortunately,
trade-offs must be made between these considerations. Pack
size and weight are particularly important for activities
like hiking and canoeing with lots of portages, so down or
Lite Loft bags are recommended.
Do you
sleep still or move around a lot?
Who
will use it, and what size and shape should it be?
Rectangular bags are roomy and most like a normal duvet or
blanket. They are often chosen by casual, family, or
first-time campers for their comfort and versatility.
Tapered bags are wide in the shoulders and narrower at the
feet which increases their warmth because there is less air
space in the bag. As well, tapered sleeping bags are
slightly lighter than rectangular bags. Mummy bags, as the
name indicates, are "worn" by the user; they are
meant to fit snugly to the body and to move with the user.
As a result of the close fit, mummy bags are warmer and
lighter than rectangular and tapered bags, but are less
roomy and familiar in use. Mummy bags are often chosen by
serious users who will be exposed to extreme conditions, and
who prefer the efficiency of the mummy design.
How
much am I willing to spend, considering that I will have
this bag for many years?
General
Tips
If you
are not sure what temperature rating you need, it's always
safer to buy a sleeping bag for cooler temperatures because
you can always vent through zippers at the foot or side of
the bag. Remember that temperature ratings are decided based
on the assumption of the use of a tent and sleeping pad,
which helps to insulate the bag from the cold ground.
To get
the most out of your purchase when buying two bags to be
zipped together, buy bags with different temperature ranges.
On cooler evenings put the heavier bag on top and on warmer
evenings put the lighter bag on top.
When
given the option of left or right hand zippers, left-handed
people should buy bags with the zipper on the right side and
right-handed people the left side. Reaching across your body
is a more natural and easy position in which to adjust your
zipper.
When
repacking your sleeping bag in its carry bag or stuff sack,
you should stuff it rather than roll it. Folding and rolling
the same way every time will create creases and cold spots
in the insulation.
Most
sleeping bags are washable in a front loading machine washer
with mild liquid soap. They can usually be dried in a
machine drier on low setting or line dried. Polyester fills
like Hollofil® or Woods® Hi Loft may also be dry cleaned.
(These are general rules, but always check the directions on
your own bag). Using a sleeping bag liner inside your
sleeping bag and washing only it saves the trouble of
washing the entire bag and will increase your sleeping bag's
life in the long run.
