The ultra-packable Voyager 45 Long Sleeping Bag performs in cool and damp conditions thanks to SpiraFil high-loft insulation. The unique blend of large, spiral hollow fibers and small polyester fibers provides the exceptional warmth, softness, and compressibility of natural down while increasing moisture resistance. The Voyager is also also EN rated as comfortable for men at a lower limit of approximately 45 degrees Fahrenheit. It features a full-length, locking YKK two-way zipper with a zipper garage, dual hang loops, and a blanket-like feel for all-night comfort. Rounding out this excellent bag are its “feely” draw cords and an included stuff sack that compresses for convenient packability.
