NEMO Riff

The Spoon shape is NEMO's proprietary design that adds extra room at the elbows and knees while keeping the bag tapered at the shoulders and feet. It provides the thermal efficiency of a mummy bag but allows for more natural movement, making it much more comfortable for side sleepers.

Thermo Gills are zippered vents on the top of the bag that allow you to dump excess body heat without letting in a draft. By opening them partially or fully, you can fine-tune your internal temperature on warmer nights without having to unzip the entire bag.

With a 15-degree Fahrenheit temperature rating and an ISO limit rating of 17 degrees, this bag is well-suited for three-season backpacking and early winter trips. If you tend to sleep cold, you may want to pair it with an insulated sleeping pad to maximize the warmth of the 800-fill down.

Yes, the 800-fill hydrophobic down is treated to resist moisture, meaning it retains its loft and insulating properties much better than untreated down if it gets damp. While it isn't waterproof, it offers a significant performance advantage in humid or condensation-prone environments.

The Riff packs down to approximately 11.5 by 7.5 inches, with a compressed volume of 6.2 liters. It is designed to fit efficiently into most standard backpacking packs without taking up excessive space.

The Riff is designed to accommodate users up to 78 inches, or 6'6", in height. You should have enough length to comfortably fit, though if you are right at the limit, you may want to ensure you aren't using an exceptionally thick sleeping pad that could reduce the internal length.
