Description

The Nemo Riff Endless Promise is an 800 fill-power down sleeping bag rated to -2°C ISO comfort and -8°C ISO limit, weighing 1.19 kg in the Regular. It uses Nemo's Ultralight Spoon shape, cut wider at the elbows and knees so side sleepers can move, and has Thermo Gill chest vents for dumping heat without opening the bag.

Who it's for

Backpackers who sleep on their side and are tired of being pinned flat by a mummy bag, but who still care about carried weight. At 1.19 kg with 800 fill-power down, the Riff sits at the lighter end of Nemo's Spoon range without dropping to a quilt.

Less suited to gram-counting alpine trips, where a narrow mummy will pack smaller for the same warmth, and to anyone who never moves in their sleep — the extra width at the elbows and knees is weight you would not be using.

Key features

  • Ultralight Spoon shape — wider at the elbows and knees than a mummy, narrower at the head and foot than a rectangular bag. That is how it buys room to roll over without the weight penalty.
  • 800 fill-power down — higher fill power means more loft per gram, which is why this bag is 1.19 kg where a 650FP bag of the same warmth is nearer 1.3 kg.
  • Thermo Gill vents across the chest, each with an inner and outer zip and a draft-blocking layer between them. You dump heat on a mild night without opening the bag to cold air.
  • Blanket Fold draft collar at the neck, oversized so it seals warmth in rather than needing to be cinched.
  • Zips to a second Riff to make a double, if the zips oppose.
  • Compression sack and mesh storage cube both included — the cube is what keeps the down lofted between trips.
  • Endless Promise construction: designed to be recycled at the end of its life rather than landfilled.

Reading the temperature ratings

Two numbers matter. ISO comfort, -2°C here, is the temperature a cold sleeper should stay comfortable at. ISO limit, -8°C, is where a warm sleeper is still expected to sleep, curled up. Buy on comfort, not limit. And treat the label as a starting point: your sleeping pad's R-value, what you wear and how well you have eaten all move it by several degrees.

Riff versus Disco

Both are Nemo Spoon bags with Thermo Gills. The Riff uses 800 fill-power down and weighs 1.19 kg; the Disco uses 650 fill-power and weighs about 1.3 kg for a colder -3°C comfort rating. Riff is the lighter, more packable bag for the warmth; Disco is the better value if weight matters less than price.

FAQ's

How cold can you use the Nemo Riff sleeping bag?
The Riff is rated to -2°C ISO comfort and -8°C ISO limit. Comfort is the figure to buy on: it is where a cold sleeper should stay comfortable. The limit rating assumes a warm sleeper curled up and is not a temperature to plan a trip around.

What is the Spoon shape and does it suit side sleepers?
Nemo's Spoon silhouette is cut wider at the elbows and knees than a mummy bag while staying narrow at the head and feet. Side sleepers get room to bend a knee and tuck an arm without dragging the whole bag around, and it avoids the weight of a full rectangular bag.

What is the difference between the Nemo Riff and the Nemo Disco?
Both are Spoon-shaped bags with Thermo Gill vents. The Riff uses 800 fill-power down at 1.19 kg; the Disco uses 650 fill-power and is heavier for its warmth. Choose the Riff for lower weight and better packability, and the Disco if price matters more than grams.

What does 800 fill power actually mean?
Fill power measures how much loft a given weight of down produces, and loft is what traps warm air. At 800 fill power the Riff needs only 540 g of down in the Regular to reach its rating, which is why it packs smaller and weighs less than a comparable 650 fill-power bag.

Can two Nemo Riff bags be zipped together?
Yes, Nemo lists the Riff among its bags that zip together. You need two bags with opposing zip sides for this to work, so check the zip orientation of both before buying if a double is what you are after.

How should I store a down sleeping bag between trips?
Store the Riff lofted in the mesh storage cube it comes with, not compressed in its stuff sack. Down that is kept crushed for months loses loft permanently, and loft is the whole mechanism by which it keeps you warm. Use the compression sack only for carrying.
