The Blaze series sleeping bags are constructed with a durable, polyester ripstop shell with a soft polyester liner and are filled with synthetic TechLoft Silver insulation. TechLoft Silver insulation consists of multiple denier staple-length fibers that have a siliconized finish for maximum insulation, loft, and compactness. The Blaze uses two-layer off-set construction featuring a contoured hood and mummy shape, which help seal in your warmth.
