- POLARGUARD® continuous filament polyester 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® continues to be the continuous filament insulation used by the U.S. military in sleeping bags today.)
- POLARGUARD® HV insulation was launched in August, 1992. It was 25% 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 is a softer, and more compressible version of of POLARGUARD® HV. It is made with 3.5 denier, hollow continuous filament fiber. POLARGUARD® 3D was shown initially in premium-priced high-performance jackets and vests and easily moved into sleeping bags. Test conducted by Kansas State University found POLARGUARD® 3D insulation provided the best thermal efficiency per unit weight of the major synthetic fills on the market.
- 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® continues to be in the forefront of technological development. Our dedicated team of R&D members have developed new products that are currently being field tested and will be available to the market soon.
- POLARGUARD® X200 is made with a blend of fibers and deniers that makes it softer and the most packable insulation of the POLARGUARD® family.
