Hoechst Celanese's high-loft, synthetic insulation of 100 percent polyester continuous-filament fibers. Polarguard is one of the original and most durable synthetic fills, but is somewhat bulky when stuffed. The HV version uses hollowed fibers, is about 25 percent more stuffable, and retains the original Polarguard?s longevity.
The History of POLARGUARD:
* 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® ? 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.
This bag was purchased in 1995. It has endured all I could dish out. In those days I was less careful in handling my equipment and have given this bag alot of abuse. The bag was amoung the lighted and warmest when it was purchased, but now it is one of the heaviest bags by comparison. It does not compress down to the size of todays bags either so, with those two things it gets left behind these days.
The current condition of the bag proves that the statements of The North Face company regarding their products is a fact beyond dispute.
