Nemo Riff Endless Promise Down Sleeping Bag – Long, Azure | Ultralight with Thermo Gill and Blanket Fold

Meet the Nemo Riff Endless Promise Down Sleeping Bag in Long, finished in Azure. This thoughtful piece blends lightweight warmth with intelligent design, helping you rest well on cold nights without weighing you down. Built to travel with you, it emphasizes comfort, sustainability, and versatile use in a wide range of campsites and seasons.

Move freely, stay warm

The spoon-shaped silhouette creates elbow and knee room, so you can shift positions naturally while maintaining efficient warmth. A compact profile keeps you moving toward camp miles earlier, without compromising comfort on a late-season stop.

Thermo Gill vents work in concert with a multistage zipper system to provide fine-tuned climate control. You can seal in warmth on a windy night or improve airflow when temperatures rise, making this bag adaptable for a spectrum of conditions from alpine evenings to damp forest candlelight.

Cozy warmth with smart draft control

The Blanket Fold design introduces an oversized draft collar that blocks drafts when you want extra insulation and loosens to release warmth when needed. This feature helps balance temperature without the need for layering inside the bag.

Environmentally minded design is embedded at every step: the Endless Promise program backs recyclability at end of life, while the fill is 800 fill power hydrophobic, PFAS-free, and RDS-certified down. These choices support performance you can feel and a supply chain built with animal welfare in mind.

In practice, this sleeping bag blends performance and responsibility. It pairs a calm, compact feel with the kind of warmth that makes a chilly night feel predictable rather than daunting. It’s suitable for weekend backpacking, hut-to-hut trips, and car or tent camping where you value efficiency without sacrificing comfort.
