- POLARGUARD® continuous filament insulation was introduced in the 1970's. The
original POLARGUARD® insulation was made with 5
denier, solid continuous filament fibers used in
sleeping bags and extreme weather outerwear.
- During the 1980's the U.S. military specified continuous filament for use in
its extreme cold weather sleep system.
- POLARGUARD® HV insulation was launched in August 1992. It was 25 percent lighter
than the original product and featured a curvilinear
triangular hollow cross section to trap more air,
making it warmer.
- POLARGUARD® 3D insulation was introduced in 1996. POLARGUARD® 3D insulation
is a softer, and more compressible version of POLARGUARD®
HV insulation. It is made with 3.5 denier, hollow
continuous filament fiber. POLARGUARD® 3D insulation
was initially used in premium-priced, high-performance
jackets and vests and easily moved into sleeping
bags.
- POLARGUARD® Δ insulation was launched in 2000. It features a super void (larger
hollow), 4 denier fiber with a modified batt formation
to make it more compressible, lighter and warmer.
- POLARGUARD® X200 insulation is made with lower denier polyester staple fiber
that makes it softer and is the most packable insulation
in the POLARGUARD® family of insulation products.
