Let's go camping (3) ~ Sleeping bag
Cheap sleeping bag v.s. down sleeping bag
Today, I am talking about sleeping bags. A sleeping bag is one of essential camp
gars. The price range is vary, some of
inexpensive one could start around USD$20 in many discount stores, such as
Walmart, Target and etc. in the US. On
the other hand, people can find much expensive one in many outdoor stores. Some sleeping bags that are designed for very
extreme use is some time more than USD$1,000!!
I guess many people who are looking for a sleeping bag for the first time
might wonder what would be difference between them.
General guide line
There are a couple factors to select a sleeping bag
depending on usage.
·
Packed size
·
Insulation (heat retention)
·
Insulation material (synthetic fill / down /
etc.)
A
major factor that impacts to the cost / price is insulation material. Most of insulation material for sleeping
bags for backpacking / climbing uses a special material that can pack
smaller. That is one of reason those
sleeping bag is more expensive. Down is
one of the best insulation materials for sleeping bags. Sleeping bag with down can pack very small
and heat retention is very well. There
are different type of down and price is vary, especially one for very extreme
condition like special winter climbing.
Those special purpose, people know what they need very well. Since down is very good material for sleeping
bags, people develop many synthetic material like down. Nowadays, synthetic materials are getting
improved and work very well. However,
the packed size is relatively a little bigger than one with down. Typically, if heat retention performance is a
similar, one with synthetic is less expensive than one with down. However, the price for one that is typically
used for a regular camping seasons, spring to fall, is getting very
similar. If people can spend around
USD$150 ~ 200, then people can find a good sleeping bag.
One
of disadvantage on sleeping bags with down is heat retention in wet condition. As long as down is dry, it is very good heat
retention. However, once it gets wet,
the heat retention is getting worse significantly. People who use a sleeping bag with down needs
to have a good care to avoid it is getting wet.
Some of outer shell is using GoreTex that can breath, some people using
a cover with GoreTex. GoreTex or other
breathable material helps to block moisture from the outside and take away
moisture in side.
On
the other hand synthetic material is much better heat retention performance
even if it gets wet. Also it is much
easy to maintain after use. Most of
synthetic materials are washable.
Disadvantage for synthetic material is relatively heavier and packed
size is a little bigger.
People
need to know what environment they plan to use a sleeping bag. Then they can narrow down which would be a
good selection for them.
Here is some guide line to select a sleeping bag
Family Camper
This is a group that typically does camping next a car. The packing size is usually not a concern. Most of case, family camping is around summer
season; therefore, one that is sold in a discount store is typically good
enough. If people want to save some
packed space, people always can buy nice sleeping bag from outdoor store with
some extra money.
They are from a discount store (40F and 50F)
Backpack camper
Since people need to carry all gear with a backpack, the
packing size and weight are one of key factors to select one. People usually do not want to buy really
cheap sleeping bag from discount stores.
They are usually really big packed size and heavy. Most of cases people want to spend some extra
money to buy a better sleeping bag.
Depending on a place, the heat retention can be
various. Especially, hikers / climbers
who typically have camping in higher altitude, they probably need one that is
capable around 0 degree C for summer camping.
People who need to sleep in snow; they probably need a really good
sleeping bag. However they must know
what they need, therefore, I do not discuss / explain in this article.
Down Sleeping bags

Summary
I think most of back packers / hikers / climbers are usually
experience people for camping. They
usually know what they need. People who
really need advice which sleeping bag they need to buy are really beginners. The easiest way is probably just buying low
cost sleeping bag from discount stores and try some easy camping first. If people do not see any problem, that would
be a good one for them. If people feel
cold, then those people may need a better sleeping bag. If people think the packed size is too big,
then those people need to look for a good sleeping bag from outdoor
stores. I think most of cases for
family style camping; low cost sleeping bag is usually enough. If people have a concern for temperature,
just bring extra blanket or closes.
