Sleeping Bag Insulations and their Benefits
Sleeping Bag Insulations and their Benefits
by: Jimmy Zambrano
Sleeping bags are sold in different styles (mummy, rectangular, hooded, and kids' sleeping bags), for
varying temperatures (extreme weather, cold weather, three season, and warm weather sleepingbags), and with many different insulations (synthetic fibers and down fill). Sleeping bag insulations
should be considered when purchasing your next bag. Here are some commonly used insulations
and their benefits.
Slumberloft HQ(TM)
is a synthetic fiber composed of a 50% hollow core polyester fiber joined with a 50% solid core
polyester fiber. This combination offers great warmth and loft. Examples of sleeping bags with
Slumberloft HQ are: Slumberjack - Latitude, Long -20F/-29C and Slumberjack - Lil' Timber, Kids Bag
+10F/-12C.
DuPont Hollofil 808
is a synthetic fiber. Its hollow core is designed to trap more air for greater warmth and loft.
Examples of sleeping bags Camping sleeping bagwith this insulation are: Coleman - Crescent
+15F/-9C and Coleman - Mountain Lodge, King -5F/-21C.
DuPont Hollofil II
is a synthetic fiber that features four hollow tunnels that run throughout its length. With four
compartments per fiber to trap air, it typically provides even more warmth and compactibility than
Hollofil 808. An example of a sleeping bag with this insulation is: Coleman Exponent - Northbound
+0F/-18C.

is a high performance insulation that blends three different fibers - fine denier fibers, thermal
bonding fibers, and hollow core spring fibers. This tri-blend fiber system offers ultimate warmth andsuperior compactibility. Examples of sleeping bags with this insulation are: Slumberjack - Diablo
+40F/+4C and Slumberjack - Odyssey, Long +10F/-12C.
DuPont Thermolite Extra
is a high-loft, high-resilient technical insulation for extraordinary warmth. Because it is made from
unique patented hollow-core, three-dimensional crimp having a helical configuration, it provides
superior loft, compactness, and exceptional resiliency. An example of a sleeping bag with this
insulation is: Slumberjack - Telluride, Long +30F/-1C.
Polarguard HV
is a high-performance insulation made of high-void, continuous-length polyester filaments that are
bonded into a batting of multiple layers. Because it is a continuous filament, Polarguard HV does not
shift, clump, or separate. An example of a sleeping bag with this insulation is: Coleman Exponent -
Boulder Ridge +20F/-7C.
Polarguard 3D
is a high performance insulation produced from continuous filament in the same manner but finerthan Polarguard HV. This makes Polarguard 3D softer, more compressible and stronger while
providing great insulating value and loft. Examples of sleeping bags with this insulation are: Sierra
Designs - Paul Bunyan, Long +10F/-12C and Sierra Designs - Rosa, Regular +20F/-7C - Women's
sleeping bag.
Polarguard Delta
continuous filament polyester is the newest member of the Polarguard family. Polarguard Delta
combines a super void cross section with modified batt formation. The larger void creates higher loft
with less weight, making it warmer, yet lighter. An example of a sleeping bag with this insulation is:
Sierra Designs - LX, Regular +45F/+7C.
Down

is a time honored, expedition proven natural insulation made of very small extremely light down
plumules found next to the skin of geese. For its weight, down has an exceptional ability to trap air,
making it the most efficient warmth to weight insulation available. Examples of sleeping bags with
this insulation are: Kelty - Light Year Down, Long +15F/-9C and The Backside - Blue Ice -50F/-46C
(750 Down).
ThermoTech
exclusive to Coleman, is made of solid-core fibers and is soft and lofty with good thermal retention,
properties to keep campers warm. Generally used for mild condition bags, this insulation keeps
campers snug on cool summer nights. Made of 100 percent polyester fibers, which are non-
allergenic, machine washable, and odorless. Examples of sleeping bags with this insulation are:
Coleman for Kids - Journey Junior +40F/+4C and Coleman for Kids - Voyager +40F/+4C.
Coletherm
also exclusive to Coleman, is a hollow-core fiber, allowing for greater loft (a measure of the amount
of space the insulation occupies and the amount of air the insulation can trap). The hollow-core
fibers create pockets of air that serve as an extra barrier between the sleeper and the environment,
maximizing thermal efficiency. Made of 100 percent polyester fibers, which are non-allergenic,
machine washable, and odorless. An example of a sleeping bag with this insulation is: Coleman
Exponent - Big Basin +0F/-18C.
Buckloft
is a fine denier, solid core polyester fiber. This combination offers outstanding warmth with extra
loft. An example of a sleeping bag with this insulation is: Slumberjack - Kenai +0F/-18C.
Buckloft HQ
is a synthetic fiber composed of a 25% siliconized, hollow-core polyester fiber joined with a 75%
solid core polyester fiber. This combination offers great warmth and comfort. An example of a
sleeping bag with this insulation is: Slumberjack - Chaparral -30F/-34C.
Kelty CloudLoft
is Kelty's affordable and durable branded synthetic fill insulation. The blend of solid core and hollow
core fibers trap heat efficiently and provide excellent loft and comfort. Cloudloft is used in Kelty'smost value-oriented mummy and rectangular bags. An example of a sleeping bag with this insulation
is: Kelty - Mistral, Long +20F/-7C.
