PolarguardÂ® Delta continuous filament polyester is the newest member of the Polarguard Family of Insulation Products. Using the latest advances in fiber technology, Polarguard Delta insulation is lightweight, and has greater thermal efficiency. Following in the Polarguard tradition, Polarguard Delta retains the highâ€“performance characteristics of continuous filament, including durability, dimensional stability, superior loft retention and unsurpassed warmth, even when wet. Unlike cut staple insulation, Polarguard will not mat, clump or pull apart, which can cause cold spots to form.
Polarguard Delta combines a super void cross section with modified batting formation. The larger void creates higher loft with less weight, making it warmer, yet lighter. The result is a state-of-the art insulation that offers superior performance in sleeping bags and outdoor apparel under the harshest environments.
