Stuffed to the maximum with Eureka!® Synthesis Performance Insulation – Eureka!'s lightest-weight, most compressible insulation yet – the Kiewa 20°F Sleeping Bag not only keeps you warm when the temperature drops, it also packs down to a super-small size to easily travel with you anywhere. Synthetic fiber-blend insulation delivers long-lasting heat retention to ensure you sleep comfortably in conditions down to 20°F, while the peached polyester lining and full-length insulated zipper draft tube with anti-snag guard prevent warmth from being stolen by wind overnight. Lightweight tapered shape can be fully unzipped for use as a blanket, or mated with an identically sized Kiewa bag to create a cozy two-person sleeping bag. Low-profile 3-D footbox delivers plenty of room to move around. Locking two-way zipper allows you to make adjustments for improved air circulation and cooling ventilation. Internal pocket keeps valuables within easy reach. Included compression stuff sack. 40-denier, 290-thread-count polyester-taffeta shell and 50-denier, 300-thread-count peached polyester lining. Imported.
