Marmot Nanowave 45 Sleeping Bag regular brick

If an epic kayaking trip or bike tour around Europe is on the schedule, the Nanowave 45 Sleeping Bag will easily compress into the stern or pannier—essential for on-the-go exploring when space and weight are at a premium. Spirafil high loft insulation's 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 NanoWave is also EN tested to provide a comfortable night’s sleep for women to the comfort level of approximately 56.1°F and a lower limit for men of approximately 49.6°F. It features a dual-zipper design: a full-length anti-snag main zipper, plus a second fold-down zipper for added ventilation and easy access. The anatomically shaped footbox minimizes heat buildup and gives you plenty of room to get comfortable. The bag’s top portion is built for maximum loft and warmth, while the bottom portion retains a blanket-like feel for all-night comfort. Rounding out this travel-ready sleeping bag are “feely” draw cords, dual hang loops, and a stuff sack that compresses for convenient packability.
